What is Triaminic Softchews Allergy Sinus (acetaminophen and pseudoephedrine)?

Acetaminophen is a pain reliever and a fever reducer.


Pseudoephedrine is a decongestant that shrinks blood vessels in the nasal passages. Dilated blood vessels can cause nasal congestion (stuffy nose).


The combination of acetaminophen and pseudoephedrine is used to treat headache, fever, body aches, stuffy nose, and sinus congestion caused by allergies, the common cold, or the flu.


Acetaminophen and pseudoephedrine may also be used for purposes not listed in this medication guide.


What is the most important information I should know about Triaminic Softchews Allergy Sinus (acetaminophen and pseudoephedrine)?


Do not take more of this medication than is recommended. An overdose of acetaminophen can damage your liver or cause death. Do not take this medication without a doctor's advice if you have ever had alcoholic liver disease (cirrhosis) or if you drink more than 3 alcoholic beverages per day. Do not use this medicine if you have untreated or uncontrolled diseases such as glaucoma, asthma or COPD, high blood pressure, heart disease, coronary artery disease, or overactive thyroid. Avoid drinking alcohol. It may increase your risk of liver damage while taking acetaminophen. Do not use acetaminophen and pseudoephedrine if you have used an MAO inhibitor such as furazolidone (Furoxone), isocarboxazid (Marplan), phenelzine (Nardil), rasagiline (Azilect), selegiline (Eldepryl, Emsam, Zelapar), or tranylcypromine (Parnate) in the last 14 days. A dangerous drug interaction could occur, leading to serious side effects. Ask a doctor or pharmacist before using any other pain, cold, allergy, or sleep medication. Acetaminophen (sometimes abbreviated as APAP) is contained in many combination medicines. Taking certain products together can cause you to get too much acetaminophen which can lead to a fatal overdose. Check the label to see if a medicine contains acetaminophen or APAP.

VA Class: VT100
Chemical Name: 5,6-dimethyl-benzimidazolyl cyanocobamide,
CAS Number: 68-19-9
Brands: Nascobal

Introduction

A cobalt-containing, B complex vitamin.a Cyanocobalamin and hydroxocobalamin are synthetic forms of vitamin B12.a


Hydroxocobalamin: Antidote for cyanide poisoning.104


Uses for Vitamin B12


Vitamin B12 Deficiency


Treatment of pernicious anemia and other vitamin B12 deficiency states.a 102 105


Parenteral cyanocobalamin or hydroxocobalamin: Treatment of vitamin B12 deficiency due to inadequate intrinsic factor (IF) secretion; impaired intestinal absorption; or dietary deficiency associated with a vegetarian diet.a 102 105


Cyanocobalamin is considered the parenteral vitamin B12 preparation of choice; hydroxocobalamin may be preferred for initial treatment.a


Cyanocobalamin nasal spray: Used to maintain hematologic status in adults with pernicious anemia with no nervous system involvement who have responded to parenteral vitamin B 12 therapy.103 Also used as a supplement for vitamin B12 deficiency due to dietary deficiency, impaired absorption, inadequate secretion of IF, or certain other conditions.103


Dietary Requirements


Adequate intake needed to prevent vitamin B12 deficiency and neurologic complications associated with vitamin B12 deficiency.101


Adequate intake of vitamin B12 usually can be accomplished through consumption of foodstuffs; however, about 10–30% of geriatric individuals are unable to absorb naturally occurring vitamin B12 and should consume vitamin B12-fortified food or supplements.101 Inadequate intake can occur in vegetarians and their breast-fed infants.a Mixed foods whose main ingredient is meat, fish, or poultry; milk; and fortified ready-to-eat cereals are the main sources of vitamin B12 in the diet of US adults and children.101


Recommended Dietary Allowance (RDA) in adults based on amount needed to maintain hematologic status and normal serum vitamin B12 concentrations.101


Adequate intake (AI) established for infants ≤6 months of age based on observed mean vitamin B12 intake of infants fed principally human milk; AI for infants 7–12 months of age based on AI for younger infants and data in adults.101


RDA for children 1–18 years of age based on data in adults.101


Metabolic Disorders


Parenteral cyanocobalamin: Management of hereditary deficiency of transcobalamin II.a


Schilling Test


Parenteral cyanocobalamin and hydroxocobalamin: Used in conjunction with cyanocobalamin Co 57 in Schilling test to study vitamin B12 absorption. a


Cyanide Poisoning


Hydroxocobalamin (Cyanokit): Treatment of known or suspected cyanide poisoning.104 107 108 109 Used in conjunction with airway and cardiovascular support and management of seizure activity.104


Vitamin B12 Dosage and Administration


Administration


Cyanocobalamin is administered orally, intranasally, or by IM or deep sub-Q injection.a 102 103


Hydroxocobalamin is administered by IM injection or IV infusion.104 105


Oral Administration


Oral therapy is inferior to parenteral therapy. a May be used for treatment of dietary vitamin B12 deficiency in patients with normal GI absorption.a


Parenteral Administration


Cyanocobalamin: Administer by IM or deep sub-Q injection.102 If administered sub-Q, avoid injection into the dermis or upper subcutaneous tissue.a Avoid administering IV; vitamin is rapidly excreted in urine when administered IV.102


Hydroxocobalamin: Administer by IM injection (vitamin deficiency)105 or by IV infusion (cyanide poisoning).104 Avoid administering IV for vitamin deficiency.105


For drug compatibility information, see Compatibility under Stability.


IV Administration for Cyanide Poisoning


Hydroxocobalamin: (Cyanokit); Administer by IV infusion.104


May require a dedicated IV line.104 Administration through the same IV line as blood products not recommended.104


Reconstitution

Reconstitute vial containing 2.5 g of hydroxocobalamin with 100 mL of 0.9% sodium chloride injection; invert or rock vial for at least 30 seconds.104 Do not shake vial.104 Lactated Ringer's injection or 5% dextrose injection can be used if 0.9% sodium chloride injection is not available.104 Reconstituted solution contains 25 mg/mL.104


Rate of Administration

Initial 5-g dose: 15 minutes.104


Second 5-g dose: 15 minutes (for patients in extremis) to 2 hours; rate depends on patient condition.104


Intranasal Administration


Administer intranasally using a metered-dose pump.103 Administer 1 hour before or 1 hour after ingestion of hot foods or liquids.103


Prior to intranasal administration, clear nasal passages.110 Insert the nasal adapter 1 cm into one nostril, point the tip of the adapter toward the back of the nose, hold the other nostril closed, and tilt head slightly forward, pump the drug into nostril, sniff gently during and immediately after dosing, return head to upright position, remove pump unit from nose.110 a


Efficacy has not been established in patients with nasal congestion, allergic rhinitis, or upper respiratory tract infection; defer use until these symptoms have subsided.103


Prime the pump before each use.103


Dosage


Vitamin B 12 deficiency: Duration of therapy depends on cause; long-term therapy not needed when other therapeutic measures correct the underlying cause of the deficiency.a

Ocular Effects

Avoid use in patients with early Leber’s disease (hereditary optic nerve atrophy); rapid and severe optic nerve atrophy reported.102 103


Sensitivity Reactions


Sensitivity Reactions

Anaphylaxis reported with parenteral preparations.102 103


Hydroxocobalamin (Cyanokit): Rash, mainly acneiform, reported in 20 or 44% of individuals receiving a 5- or 10-g dose, respectively.104


Skin Test

Administer an intradermal test dose prior to administration of vitamin B12 for vitamin deficiency in patients who may be sensitive to cobalamins.a


General Precautions


Laboratory Monitoring

Obtain hematocrit, reticulocyte count, vitamin B12, folate, and iron levels prior to treatment for vitamin B12 deficiency.102 103 Monitor hematologic parameters as necessary during therapy.102 103


Aluminum

Some cyanocobalamin injection preparations contain aluminum, which may be toxic.102 Aluminum may reach toxic levels with prolonged parenteral administration if kidney function is impaired.102 Premature neonates are particularly at risk because their kidneys are immature, and they require large amounts of calcium and phosphate solutions, which contain aluminum.102


Research indicates that patients with impaired kidney function, including premature neonates, who receive parenteral levels of aluminum >4–5 mcg/kg daily accumulate aluminum at levels associated with CNS and bone toxicity.102 Tissue loading may occur at even lower rates of administration.102


Benzyl Alcohol in Neonates

Cyanocobalamin injection may contain benzyl alcohol as a preservative; benzyl alcohol has been associated with toxicity in neonates.102 111 112 113 114 115 116 (See Pediatric Precautions.)


Blood Pressure

Transient elevations in BP reported in individuals receiving IV hydroxocobalamin.104


Undiagnosed Anemia

Use extreme caution if folic acid is administered to patients with undiagnosed anemia; may obscure the diagnosis of pernicious anemia by alleviating hematologic manifestations of the disease while allowing neurologic complications to progress.a


Renal Effects

Oxalate crystals observed in the urine of healthy individuals and cyanide poisoning victims following administration of hydroxocobalamin.104


Specific Populations


Pregnancy

Category C.102 103 104 105

ActionsActions



  • An exogenous source of vitamin B12 is required for nucleoprotein and myelin synthesis, cell reproduction, normal growth, and the maintenance of normal erythropoiesis.a




  • In cyanide poisoning, hydroxocobalamin binds to the cyanide ion to form cyanocobalamin which is excreted in the urine.104



Advice to Patients



  • Advise patients with pernicious anemia that they must receive maintenance dosages of cyanocobalamin or hydroxocobalamin for the remainder of their lives to prevent irreversible neurologic damage.a




  • Advise patient of necessity of follow-up tests to confirm adequacy of therapy.103




  • Advise individuals who follow a vegetarian diet that contains no animal products to take oral vitamin B12 regularly.102 103




  • Importance of informing patients using intranasal cyanocobalamin to administer the dose at least 1 hour before or after ingestion of hot foods or liquids.103




  • Importance of informing clinicians of existing or contemplated concomitant therapy, including prescription and OTC drugs, as well as any concomitant illnesses.102 103




  • Importance of women informing clinicians if they are or plan to become pregnant or plan to breast-feed.102 103 Importance of vitamin B12 supplements in pregnant and lactating women who follow a vegetarian diet.102 103 Advise women given hydroxocobalamin for cyanide poisoning to discuss timing of resumption of breast-feeding with their clinician.104




  • Advise patients given hydroxocobalamin for cyanide poisoning that skin redness may last up to 2 weeks and urine coloration may last up to 5 weeks.104 Importance of avoiding direct sun exposure while skin is discolored.104

Triostat



liothyronine sodium

Dosage Form: injection
Triostat®

brand of liothyronine sodium injection (T3)

PRESCRIBING INFORMATION



Triostat Description


Thyroid hormone drugs are natural or synthetic preparations containing tetraiodothyronine (T4, levothyroxine) sodium or triiodothyronine (T3, liothyronine) sodium or both. T4 and T3 are produced in the human thyroid gland by the iodination and coupling of the amino acid tyrosine. T4 contains four iodine atoms and is formed by the coupling of two molecules of diiodotyrosine (DIT). T3 contains three atoms of iodine and is formed by the coupling of one molecule of DIT with one molecule of monoiodotyrosine (MIT). Both hormones are stored in the thyroid colloid as thyroglobulin and released into the circulation. The major source of T3 has been shown to be peripheral deiodination of T4. T3 is bound less firmly than T4 in the serum, enters peripheral tissues more readily, and binds to specific nuclear receptor(s) to initiate hormonal, metabolic effects. T4 is the prohormone which is deiodinated to T3 for hormone activity.


Thyroid hormone preparations belong to two categories: (1) natural hormonal preparations derived from animal thyroid, and (2) synthetic preparations. Natural preparations include desiccated thyroid and thyroglobulin. Desiccated thyroid is derived from domesticated animals that are used for food by man (either beef or hog thyroid), and thyroglobulin is derived from thyroid glands of the hog.


Triostat (liothyronine sodium injection) (T3) contains liothyronine (L-triiodothyronine or L-T3), a synthetic form of a natural thyroid hormone, as the sodium salt.


The structural and empirical formulas and molecular weight of liothyronine sodium are given below.



L-Tyrosine, 0-(4-hydroxy-3-iodophenyl)-3,5-diiodo-, monosodium salt


In euthyroid patients, 25 mcg of liothyronine is equivalent to approximately 1 grain of desiccated thyroid or thyroglobulin and 0.1 mg of L-thyroxine.


Each mL of Triostat in amber-glass vials contains, in sterile non-pyrogenic aqueous solution, liothyronine sodium equivalent to 10 mcg of liothyronine; alcohol, 6.8% by volume; anhydrous citric acid, 0.175 mg; ammonia, 2.19 mg, as ammonium hydroxide.



Triostat - Clinical Pharmacology


Thyroid hormones enhance oxygen consumption by most tissues of the body and increase the basal metabolic rate and the metabolism of carbohydrates, lipids and proteins. In vitro studies indicate that T3 increases aerobic mitochondrial function, thereby increasing the rates of synthesis and utilization of myocardial high-energy phosphates. This, in turn, stimulates myosin ATPase and reduces tissue lactic acidosis. Thus, thyroid hormones exert a profound influence on virtually every organ system in the body and are of particular importance in the development of the central nervous system.


While the source of levothyroxine (T4) and some triiodothyronine (T3) is via secretion from the thyroid gland, it is now well-established that approximately 80% of circulating T3 arises predominantly by way of the extrathyroidal conversion of T4. The membrane-bound enzyme responsible for this reaction is iodothyronine 5'-deiodinase. Activity of the enzyme is greatest in the liver and kidney. A second pathway of T4 to T3 conversion occurs via a PTU-insensitive 5'-deiodinase located primarily in the pituitary and central nervous system.


The prohormone T4 must be converted to T3 in the body before it can exert biological effects. During periods of illness or stress, this conversion is often inhibited and can be diverted to the inactive reverse T3 (rT3) moiety. Therefore, correction of the hypothyroid condition in patients with myxedema coma is facilitated by the parenteral administration of triiodothyronine (T3). T3 is bound much less firmly to serum binding proteins and therefore penetrates into the cells much more rapidly than T4. Also, the binding of T3 to a nuclear thyroid hormone receptor seems to initiate most of the effects of thyroid hormone in tissues. Although most thyroid hormone analogs, both natural and synthetic, will bind to this protein, the affinity of T3 for this receptor is roughly 10-fold higher than that of T4. Thus, T3 is the biologically active thyroid hormone.



Pharmacodynamics


The clinical features of myxedema coma include depression of the cardiovascular, respiratory, gastrointestinal and central nervous systems, impaired diuresis, and hypothermia. Administration of thyroid hormones reverses or attenuates these conditions. Thyroid hormones increase heart rate, ventricular contractility and cardiac output, as well as decrease total systemic vascular resistance. They also increase the rate and depth of respiration, motilityof the gastrointestinal tract, rapidity of cerebration, and vasodilatation. Thyroid hormones correct hypothermia by markedly increasing the basal metabolic rate, as well as the number and activity of mitochondria in almost all cells of the body.



Pharmacokinetics


Since liothyronine sodium (T3) is not firmly bound to serum protein, it is readily available to body tissues.


Liothyronine sodium has a rapid cutoff of activity which permits quick dosage adjustment and facilitates control of the effects of overdosage, should they occur.


The higher affinity of levothyroxine (T4) as compared to triiodothyronine (T3) for both thyroid-binding globulin and thyroid-binding prealbumin partially explains the higher serum levels and longer half-life of the former hormone. Both protein-bound hormones exist in reverse equilibrium with minute amounts of free hormone, the latter accounting for the metabolic activity. T4 is deiodinated to T3.


A single dose of liothyronine sodium administered intravenously produces a detectable metabolic response in as little as two to four hours and a maximum therapeutic response within two days. However, no pharmacokinetic studies have been performed with intravenous liothyronine (T3) in myxedema coma or precoma patients.



Indications and Usage for Triostat


Triostat (liothyronine sodium injection) (T3) is indicated in the treatment of myxedema coma/precoma.


Triostat can be used in patients allergic to desiccated thyroid or thyroid extract derived from pork or beef.



Contraindications


Thyroid hormone preparations are generally contraindicated in patients with diagnosed but as yet uncorrected adrenal cortical insufficiency or untreated thyrotoxicosis. Thyroid hormone preparations are also generally contraindicated in patients with hypersensitivity to any of the active or extraneous constituents of these preparations; however, there is no well-documented evidence in the literature of true allergic or idiosyncratic reactions to thyroid hormone.


Concomitant use of Triostat and artificial rewarming of patients is contraindicated. (See PRECAUTIONS.)



Warnings



Drugs with thyroid hormone activity, alone or together with other therapeutic agents, have been used for the treatment of obesity. In euthyroid patients, doses within the range of daily hormonal requirements are ineffective for weight reduction. Larger doses may produce serious or even life-threatening manifestations of toxicity, particularly when given in association with sympathomimetic amines such as those used for their anorectic effects.




The use of thyroid hormones in the therapy of obesity, alone or combined with other drugs, is unjustified and has been shown to be ineffective. Neither is their use justified for the treatment of male or female infertility unless this condition is accompanied by hypothyroidism.


Thyroid hormones should be used with great caution in a number of circumstances where the integrity of the cardiovascular system, particularly the coronary arteries, is suspect. These include patients with angina pectoris or the elderly, in whom there is a greater likelihood of occult cardiac disease. Therefore, in patients with compromised cardiac function, use thyroid hormones in conjunction with careful cardiac monitoring. Although the specific dosage of Triostat depends upon individual circumstances, in patients with known or suspected cardiovascular disease the extremely rapid onset of action of Triostat may warrant initiating therapy at a dose of 10 mcg to 20 mcg. (See DOSAGE AND ADMINISTRATION.)


Myxedematous patients are very sensitive to thyroid hormones; dosage should be started at a low level and increased gradually as acute changes may precipitate adverse cardiovascular events.


Severe and prolonged hypothyroidism can lead to a decreased level of adrenocortical activity commensurate with the lowered metabolic state. When thyroid-replacement therapy is administered, the metabolism increases at a greater rate than adrenocortical activity. This can precipitate adrenocortical insufficiency. Therefore, in severe and prolonged hypothyroidism, supplemental adrenocortical steroids may be necessary.


In rare instances, the administration of thyroid hormone may precipitate a hyperthyroid state or may aggravate existing hyperthyroidism.


Extreme caution is advised when administering thyroid hormones with digitalis or vasopressors. (See PRECAUTIONS–Drug Interactions.)


Fluid therapy should be administered with great care to prevent cardiac decompensation. (See PRECAUTIONS–Adjunctive Therapy.)


Precautions

General


Thyroid hormone therapy in patients with concomitant diabetes mellitus (see PRECAUTIONS–Drug Interactions, Insulin or Oral Hypoglycemics regarding interaction and dose adjustment with insulin) or insipidus or adrenal cortical insufficiency may aggravate the intensity of their symptoms. Appropriate adjustments of the various therapeutic measures directed at these concomitant endocrine diseases are required.


The therapy of myxedema coma requires simultaneous administration of glucocorticoids. (See PRECAUTIONS–Adjunctive Therapy).


Hypothyroidism decreases and hyperthyroidism increases the sensitivity to anticoagulants. Prothrombin time should be closely monitored in thyroid-treated patients on anticoagulants and dosage of the latter agents adjusted on the basis of frequent prothrombin time determinations.


Oral therapy should be resumed as soon as the clinical situation has been stabilized and the patient is able to take oral medication. If L-thyroxine rather than liothyronine sodium is used in initiating oral therapy, the physician should bear in mind that there is a delay of several days in the onset of L-thyroxine activity and that intravenous therapy should be discontinued gradually.



Adjunctive Therapy


Many investigators recommend that corticosteroids be administered routinely in the initial emergency treatment of all patients with myxedema coma. Patients with pituitary myxedema should receive adrenocortical hormone replacement therapy at or before the start of Triostat therapy. Similarly, patients with primary myxedema may also require adrenocortical hormone replacement therapy since a rapid return to normal body metabolism from a severely hypothyroid state may result in acute adrenocortical insufficiency and shock.


In considering the need to elevate blood pressure, it should be kept in mind that tissue metabolic requirements are markedly reduced in the hypothyroid patient. Because arrhythmias and circulatory collapse have infrequently occurred following the concomitant administration of thyroid hormones and vasopressor therapies, use caution when administering these therapies concomitantly. (See PRECAUTIONS–Drug Interactions, Vasopressors.)


Hyponatremia is frequently present in myxedema coma, but usually resolves without specific therapy as the metabolic status of the patient is improved with thyroid hormone treatment. Fluid therapy should be administered with great care to prevent cardiac decompensation. In addition, some patients with myxedema have inappropriate secretion of ADH and are susceptible to water intoxication.


In some patients, respiratory depression has been a significant factor in the development or persistence of the comatose state. Decreased oxygen saturation and elevated CO2 levels respond quickly to artificial respiration.


Infection is often present in myxedema coma and should be looked for and treated appropriately.


Concomitant use of Triostat and artificial rewarming of patients is contraindicated. Although patients in myxedema coma are often hypothermic, most investigators believe that artificial rewarming is of little value or may be harmful. The peripheral vasodilation produced by external heat serves to further decrease circulation to vital internal organs and to increase shock if present. It has been reported that the administration of liothyronine sodium will restore a normal body temperature in 24 to 48 hours if heat loss is prevented by keeping the patient covered with blankets in a warm room.



Laboratory Tests


Treatment of patients with thyroid hormones requires the periodic assessment of thyroid status by means of appropriate laboratory tests besides the full clinical evaluation. Serum T3 and TSH levels should be monitored to assess dosage adequacy and biologic effectiveness.



Drug Interactions


Oral Anticoagulants

Thyroid hormones appear to increase catabolism of vitamin K-dependent clotting factors. If oral anticoagulants are also being given, compensatory increases in clotting factor synthesis are impaired. Patients stabilized on oral anticoagulants who are found to require thyroid replacement therapy should be watched very closely when thyroid is started. If a patient is truly hypothyroid, it is likely that a reduction in anticoagulant dosage will be required. No special precautions appear to be necessary when oral anticoagulant therapy is begun in a patient already stabilized on maintenance thyroid replacement therapy.


Insulin or Oral Hypoglycemics

Initiating thyroid replacement therapy may cause increases in insulin or oral hypoglycemic requirements. The effects seen are poorly understood and depend upon a variety of factors such as dose and type of thyroid preparations and endocrine status of the patient. Patients receiving insulin or oral hypoglycemics should be closely watched during initiation of thyroid replacement therapy.


Estrogen, Oral Contraceptives

Estrogens tend to increase serum thyroxine-binding globulin (TBG). In a patient with a nonfunctioning thyroid gland who is receiving thyroid replacement therapy, free levothyroxine may be decreased when estrogens are started thus increasing thyroid requirements. However, if the patient's thyroid gland has sufficient function, the decreased free thyroxine will result in a compensatory increase in thyroxine output by the thyroid. Therefore, patients without a functioning thyroid gland who are on thyroid replacement therapy may need to increase their thyroid dose if estrogens or estrogen-containing oral contraceptives are given.


Tricyclic Antidepressants

Use of thyroid products with imipramine and other tricyclic antidepressants may increase receptor sensitivity and enhance antidepressant activity; transient cardiac arrhythmias have been observed. Thyroid hormone activity may also be enhanced.


Digitalis

Thyroid preparations may potentiate the toxic effects of digitalis. Thyroid hormonal replacement increases metabolic rate, which requires an increase in digitalis dosage.


Ketamine

When administered to patients on a thyroid preparation, this parenteral anesthetic may cause hypertension and tachycardia. Use with caution and be prepared to treat hypertension, if necessary.


Vasopressors

Thyroid hormones increase the adrenergic effect of catecholamines such as epinephrine and norepinephrine. Therefore, use of vasopressors in patients receiving thyroid hormone preparations may increase the risk of precipitating coronary insufficiency, especially in patients with coronary artery disease. Therefore, use caution when administering vasopressors with liothyronine (T3).



Drug/Laboratory Test Interactions


The following drugs or moieties are known to interfere with laboratory tests performed in patients on thyroid hormone therapy: androgens, corticosteroids, estrogens, oral contraceptives containing estrogens, iodine-containing preparations and the numerous preparations containing salicylates.



  1. Changes in TBG concentration should be taken into consideration in the interpretation of T4 and T3 values. In such cases, the unbound (free) hormone should be measured. Pregnancy, estrogens and estrogen-containing oral contraceptives increase TBG concentrations. TBG may also be increased during infectious hepatitis. Decreases in TBG concentrations are observed in nephrosis, acromegaly and after androgen or corticosteroid therapy. Familial hyper- or hypothyroxine-binding globulinemias have been described. The incidence of TBG deficiency approximates 1 in 9000. The binding of thyroxine by thyroxine-binding prealbumin (TBPA) is inhibited by salicylates.




  2. Medicinal or dietary iodine interferes with all in vivo tests of radioiodine uptake, producing low uptakes which may not be reflective of a true decrease in hormone synthesis.




Carcinogenesis, Mutagenesis and Impairment of Fertility


A reportedly apparent association between prolonged thyroid therapy and breast cancer has not been confirmed and patients on thyroid for established indications should not discontinue therapy. No confirmatory long-term studies in animals have been performed to evaluate carcinogenic potential, mutagenicity, or impairment of fertility in either males or females.



Pregnancy



Pregnancy Category A: Thyroid hormones do not readily cross the placental barrier. The clinical experience to date does not indicate any adverse effect on fetuses when thyroid hormones are administered to pregnant women. On the basis of current knowledge, thyroid replacement therapy to hypothyroid women should not be discontinued during pregnancy.



Nursing Mothers


Minimal amounts of thyroid hormones are excreted in human milk. Thyroid hormones are not associated with serious adverse reactions and do not have a known tumorigenic potential. However, caution should be exercised when thyroid hormones are administered to a nursing woman.



Geriatric Use


Clinical studies of liothyronine sodium did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy. This drug is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function.



Pediatric Use


There is limited experience with Triostat in the pediatric population. Safety and effectiveness in pediatric patients have not been established.



Adverse Reactions


The most frequently reported adverse events were arrhythmia (6% of patients) and tachycardia (3%). Cardiopulmonary arrest, hypotension and myocardial infarction occurred in approximately 2% of patients. The following events occurred in approximately 1% or fewer of patients: angina, congestive heart failure, fever, hypertension, phlebitis and twitching.


In rare instances, allergic skin reactions have been reported with liothyronine sodium tablets.


For medical advice about your adverse reactions contact your medical professional. To report SUSPECTED ADVERSE REACTIONS, contact JHP at 1-866-923-2547 or MEDWATCH at 1-800-FDA-1088 (1-800-332-1088) or http://www.fda.gov/medwatch/.



Overdosage



Signs and Symptoms


Headache, irritability, nervousness, tremor, sweating, increased bowel motility and menstrual irregularities. Angina pectoris, arrhythmia, tachycardia, acute myocardial infarction or congestive heart failure may be induced or aggravated. Shock may also develop if there is untreated pituitary or adrenocortical failure. Massive overdosage may result in symptoms resembling thyroid storm.



Treatment of Overdosage


Dosage should be reduced or therapy temporarily discontinued if signs and symptoms of overdosage appear. Treatment may be reinstituted at a lower dosage. In normal individuals, normal hypothalamic-pituitary-thyroid axis function is restored in six to eight weeks after cessation of therapy following thyroid suppression.


Treatment is symptomatic and supportive. Oxygen may be administered and ventilation maintained. Cardiac glycosides may be indicated if congestive heart failure develops. Beta-adrenergic antagonists have been used advantageously in the treatment of increased sympathetic activity. Measures to control fever, hypoglycemia or fluid loss should be instituted if needed.



Triostat Dosage and Administration



Adults


Myxedema coma is usually precipitated in the hypothyroid patient of long standing by intercurrent illness or drugs such as sedatives and anesthetics and should be considered a medical emergency. Therapy should be directed at the correction of electrolyte disturbances, possible infection, or other intercurrent illness in addition to the administration of intravenous liothyronine (T3). Simultaneous glucocorticosteroids are required.


Triostat (liothyronine sodium injection) (T3) is for intravenous administration only. It should not be given intramuscularly or subcutaneously.



  • Prompt administration of an adequate dose of intravenous liothyronine (T3) is important in determining clinical outcome.




  • Initial and subsequent doses of Triostat should be based on continuous monitoring of the patient's clinical status and response to therapy.




  • Triostat doses should normally be administered at least four hours–and not more than 12 hours–apart.




  • Administration of at least 65 mcg/day of intravenous liothyronine (T3) in the initial days of therapy was associated with lower mortality.




  • There is limited clinical experience with intravenous liothyronine (T3) at total daily doses exceeding 100 mcg/day.



No controlled clinical studies have been done with Triostat. The following dosing guidelines have been derived from data analysis of myxedema coma/precoma case reports collected by SmithKline Beecham Pharmaceuticals since 1963 and from scientific literature since 1956.


An initial intravenous Triostat dose ranging from 25 mcg to 50 mcg is recommended in the emergency treatment of myxedema coma/precoma in adults. In patients with known or suspected cardiovascular disease, an initial dose of 10 mcg to 20 mcg is suggested (see WARNINGS). However, both the initial dose and subsequent doses should be determined on the basis of continuous monitoring of the patient's clinical condition and response to Triostat therapy. Normally at least four hours should be allowed between doses to adequately assess therapeutic response and no more than 12 hours should elapse between doses to avoid fluctuations in hormone levels. Caution should be exercised in adjusting the dose due to the potential of large changes to precipitate adverse cardiovascular events. Review of the myxedema case reports indicates decreased mortality in patients receiving at least 65 mcg/day in the initial days of treatment. However, there is limited clinical experience at total daily doses above 100 mcg. See PRECAUTIONS–Drug Interactions for potential interactions between thyroid hormones and digitalis and vasopressors.



Pediatric Use


There is limited experience with Triostat in the pediatric population. Safety and effectiveness in pediatric patients have not been established.



Switching to Oral Therapy


Oral therapy should be resumed as soon as the clinical situation has been stabilized and the patient is able to take oral medication. When switching a patient to liothyronine sodium tablets from Triostat, discontinue Triostat, initiate oral therapy at a low dosage, and increase gradually according to the patient's response.


If L-thyroxine rather than liothyronine sodium is used in initiating oral therapy, the physician should bear in mind that there is a delay of several days in the onset of L-thyroxine activity and that intravenous therapy should be discontinued gradually.

aspirin/chlorpheniramine/dextromethorphan/ phenylpropanolamine


Generic Name: aspirin/chlorpheniramine/dextromethorphan/ phenylpropanolamine (AS pir in/klor fen IR a meen/dex troe meth OR fan/fen ill proe pa NOLE a meen)

Brand Names: Alka Seltzer Plus Cold and Cough


What is aspirin/ chlorpheniramine/ dextromethorphan/ phenylpropanolamine?

Aspirin is in a class of drugs called salicylates. Aspirin is a pain reliever, an anti-inflammatory, and a fever reducer. It is used to treat many conditions, such as headache, muscle aches, arthritis, backache, toothaches, colds, and fevers.


Chlorpheniramine is an antihistamine. It blocks the naturally occurring chemical histamine in the body. Chlorpheniramine prevents sneezing; itchy, watery eyes and nose; and other symptoms of allergies and hay fever.


Dextromethorphan is a cough suppressant. It suppresses an area in the brain that causes coughing.


Phenylpropanolamine is a decongestant. It constricts (shrinks) blood vessels (veins and arteries). This reduces blood flow to affected areas and allows nasal passages to open up.


The combination, aspirin/chlorpheniramine/ dextromethorphan/phenylpropanolamine is used to treat nasal congestion; sinusitis (inflammation of the sinuses); headache; fever; and aches, pains, and coughs associated with allergies, hay fever, and the common cold.


Phenylpropanolamine, an ingredient in this product, has been associated with an increased risk of hemorrhagic stroke (bleeding into the brain or into tissue surrounding the brain) in women. Men may also be at risk. Although the risk of hemorrhagic stroke is low, the U.S. Food and Drug Administration (FDA) recommends that consumers not use any products that contain phenylpropanolamine.


Aspirin/chlorpheniramine/dextromethorphan/phenylpropanolamine may also be used for purposes other than those listed in this medication guide.


What is the most important information I should know about aspirin/ chlorpheniramine/ dextromethorphan/ phenylpropanolamine?


Phenylpropanolamine, an ingredient in this product, has been associated with an increased risk of hemorrhagic stroke (bleeding into the brain or into tissue surrounding the brain) in women. Men may also be at risk. Although the risk of hemorrhagic stroke is low, the U.S. Food and Drug Administration (FDA) recommends that consumers not use any products that contain phenylpropanolamine.


Use caution when driving, operating machinery, or performing other hazardous activities. Aspirin/chlorpheniramine/dextromethorphan/phenylpropanolamine may cause dizziness or drowsiness. If you experience dizziness or drowsiness, avoid these activities. Use alcohol cautiously. Alcohol may increase drowsiness and dizziness while taking aspirin/chlorpheniramine/dextromethorphan/phenylpropanolamine. Alcohol can also be damaging to the stomach when it is taken with aspirin.

Do not take more of this medication than is recommended. If your symptoms do not improve or if they worsen, see your doctor.


Who should not take aspirin/ chlorpheniramine/ dextromethorphan/ phenylpropanolamine?


Do not take this medication without first talking to your doctor if you drink more than three alcoholic beverages per day. Combined with alcohol, aspirin can be damaging to the stomach.


Do not take aspirin/chlorpheniramine/dextromethorphan/phenylpropanolamine if you have taken a monoamine oxidase inhibitor (MAOI) such as isocarboxazid (Marplan), phenelzine (Nardil), or tranylcypromine (Parnate) in the last 14 days. A dangerous drug interaction could occur, leading to serious side effects.

Before taking this medication, tell your doctor if you have



  • an ulcer,




  • a bleeding or blood clotting disorder,



  • kidney disease,

  • liver disease,


  • diabetes,




  • glaucoma,




  • any type of heart disease or high blood pressure,




  • thyroid disease,




  • emphysema or chronic bronchitis, or




  • difficulty urinating or an enlarged prostate.



You may not be able to take aspirin/chlorpheniramine/dextromethorphan/phenylpropanolamine, or you may require a dosage adjustment or special monitoring during treatment if you have any of the conditions listed above.


It is not known whether aspirin/chlorpheniramine/dextromethorphan/phenylpropanolamine will harm an unborn baby. Do not take aspirin/chlorpheniramine/dextromethorphan/phenylpropanolamine without first talking to your doctor if you are pregnant. This medication passes into breast milk and can harm a nursing baby. Do not take this medication without first talking to your doctor if you are breast-feeding a baby. If you are over 60 years of age, you may be more likely to experience side effects from aspirin/chlorpheniramine/dextromethorphan/phenylpropanolamine. You may require a lower dose of this medication. Do not use any medication that contains aspirin to treat a child or teenager who has a fever, flu symptoms, or chicken pox without first talking to a doctor. In children younger than 20 years of age, aspirin may increase the risk of Reye's syndrome, a rare but often fatal condition.

4.2 Posology And Method Of Administration



The use of docetaxel should be confined to units specialised in the administration of cytotoxic chemotherapy and it should only be administered under the supervision of a physician qualified in the use of anticancer chemotherapy (see section 6.6).



Recommended dose



For breast, non-small cell lung, gastric, and head and neck cancers, premedication consisting of an oral corticosteroid, such as dexamethasone 16 mg per day (e.g. 8 mg BID) for 3 days starting 1 day prior to docetaxel administration, unless contraindicated, can be used (see section 4.4). Prophylactic G-CSF may be used to mitigate the risk of haematological toxicities.



For prostate cancer, given the concurrent use of prednisone or prednisolone the recommended premedication regimen is oral dexamethasone 8 mg, 12 hours, 3 hours and 1 hour before the docetaxel infusion (see section 4.4).



Docetaxel is administered as a one-hour infusion every three weeks.



Breast cancer



In the adjuvant treatment of operable node-positive and node-negative breast cancer, the recommended dose of docetaxel is 75 mg/m2 administered 1-hour after doxorubicin 50 mg/m2 and cyclophosphamide 500 mg/m2 every 3 weeks for 6 cycles (TAC regimen) (see also Dose adjustments during treatment).



For the treatment of patients with locally advanced or metastatic breast cancer, the recommended dose of docetaxel is 100 mg/m2 in monotherapy. In first-line treatment, docetaxel 75 mg/m2 is given in combination therapy with doxorubicin (50 mg/m2).



In combination with trastuzumab the recommended dose of docetaxel is 100 mg/m2 every three weeks, with trastuzumab administered weekly. In the pivotal study the initial docetaxel infusion was started the day following the first dose of trastuzumab. The subsequent docetaxel doses were administered immediately after completion of the trastuzumab infusion, if the preceding dose of trastuzumab was well tolerated. For trastuzumab dose and administration, see trastuzumab summary of product characteristics.



In combination with capecitabine, the recommended dose of docetaxel is 75 mg/m2 every three weeks, combined with capecitabine at 1250 mg/m2 twice daily (within 30 minutes after a meal) for 2 weeks followed by a 1-week rest period. For capecitabine dose calculation according to body surface area, see capecitabine summary of product characteristics.



Non-small cell lung cancer



In chemotherapy naïve patients treated for non-small cell lung cancer, the recommended dose regimen is docetaxel 75 mg/m2 immediately followed by cisplatin 75 mg/m2 over 30-60 minutes. For treatment after failure of prior platinum-based chemotherapy, the recommended dose is 75 mg/m² as a single agent.



Prostate cancer



The recommended dose of docetaxel is 75 mg/m2. Prednisone or prednisolone 5 mg orally twice daily is administered continuously (see section 5.1).



Gastric adenocarcinoma



The recommended dose of docetaxel is 75 mg/m2 as a 1-hour infusion, followed by cisplatin 75 mg/m2, as a 1- to 3-hour infusion (both on day 1 only), followed by 5-fluorouracil 750 mg/m2 per day given as a 24-hour continuous infusion for 5 days, starting at the end of the cisplatin infusion. Treatment is repeated every three weeks. Patients must receive premedication with antiemetics and appropriate hydration for cisplatin administration. Prophylactic G-CSF should be used to mitigate the risk of haematological toxicities (see also Dose adjustments during treatment).



Head and neck cancer



Patients must receive premedication with antiemetics and appropriate hydration (prior to and after cisplatin administration). Prophylactic G-CSF may be used to mitigate the risk of haematological toxicities. All patients on the docetaxel-containing arm of the TAX 323 and TAX 324 studies, received prophylactic antibiotics.



• Induction chemotherapy followed by radiotherapy (TAX 323)



For the induction treatment of inoperable locally advanced squamous cell carcinoma of the head and neck (SCCHN), the recommended dose of docetaxel is 75 mg/m2 as a 1 hour infusion followed by cisplatin 75 mg/m2 over 1 hour, on day one, followed by 5-fluorouracil as a continuous infusion at 750 mg/m2 per day for five days. This regimen is administered every 3 weeks for 4 cycles. Following chemotherapy, patients should receive radiotherapy.



• Induction chemotherapy followed by chemoradiotherapy (TAX 324)



For the induction treatment of patients with locally advanced (technically unresectable, low probability of surgical cure, and aiming at organ preservation) squamous cell carcinoma of the head and neck (SCCHN), the recommended dose of docetaxel is 75 mg/m2 as a 1 hour intravenous infusion on day 1, followed by cisplatin 100 mg/m2 administered as a 30-minute to 3-hour infusion, followed by 5-fluorouracil 1000 mg/m2/day as a continuous infusion from day 1 to day 4. This regimen is administered every 3 weeks for 3 cycles. Following chemotherapy, patients should receive chemoradiotherapy.



For cisplatin and 5-fluorouracil dose modifications, see the corresponding summary of product characteristics.



Dose adjustments during treatment



General



Docetaxel should be administered when the neutrophil count is 3.



In patients who experienced either febrile neutropenia, neutrophil count < 500 cells/mm3 for more than one week, severe or cumulative cutaneous reactions or severe peripheral neuropathy during docetaxel therapy, the dose of docetaxel should be reduced from 100 mg/m2 to 75 mg/m2 and/or from 75 to 60 mg/m². If the patient continues to experience these reactions at 60 mg/m², the treatment should be discontinued.



Adjuvant therapy for breast cancer



Primary G-CSF prophylaxis should be considered in patients who receive docetaxel, doxorubicin and cyclophosphamide (TAC) adjuvant therapy for breast cancer. Patients who experience febrile neutropenia and/or neutropenic infection should have their docetaxel dose reduced to 60 mg/m² in all subsequent cycles (see sections 4.4 and 4.8). Patients who experience Grade 3 or 4 stomatitis should have their dose decreased to 60 mg/m².



In combination with cisplatin



For patients who are dosed initially at docetaxel 75 mg/m2 in combination with cisplatin and whose nadir of platelet count during the previous course of therapy is < 25,000 cells/mm3, or in patients who experience febrile neutropenia, or in patients with serious non-haematologic toxicities, the docetaxel dose in subsequent cycles should be reduced to 65 mg/m2. For cisplatin dose adjustments, see the corresponding summary of product characteristics.



In combination with capecitabine



• For capecitabine dose modifications, see capecitabine summary of product characteristics.



• For patients developing the first appearance of Grade 2 toxicity, which persists at the time of the next docetaxel/capecitabine treatment, delay treatment until resolved to Grade 0-1, and resume at 100% of the original dose.



• For patients developing the second appearance of Grade 2 toxicity, or the first appearance of Grade 3 toxicity, at any time during the treatment cycle, delay treatment until resolved to Grade 0-1 and then resume treatment with docetaxel 55 mg/m².



• For any subsequent appearances of toxicities, or any Grade 4 toxicities, discontinue the docetaxel dose.



For trastuzumab dose modifications, see trastuzumab summary of product characteristics.



In combination with cisplatin and 5-fluorouracil



If an episode of febrile neutropenia, prolonged neutropenia or neutropenic infection occurs despite G-CSF use, the docetaxel dose should be reduced from 75 to 60 mg/m2. If subsequent episodes of complicated neutropenia occur the docetaxel dose should be reduced from 60 to 45 mg/m2. In case of Grade 4 thrombocytopenia the docetaxel dose should be reduced from 75 to 60 mg/m2. Patients should not be retreated with subsequent cycles of docetaxel until neutrophils recover to a level > 1,500 cells/mm3 and platelets recover to a level > 100,000 cells/mm3. Discontinue treatment if these toxicities persist (see section 4.4).



Recommended dose modifications for toxicities in patients treated with docetaxel in combination with cisplatin and 5-fluorouracil (5-FU):














Toxicity




Dose adjustment




Diarrhoea grade 3




First episode: reduce 5-FU dose by 20%.



Second episode: then reduce docetaxel dose by 20%.




Diarrhoea grade 4




First episode: reduce docetaxel and 5-FU doses by 20%.



Second episode: discontinue treatment.




Stomatitis/mucositis grade 3




First episode: reduce 5-FU dose by 20%.



Second episode: stop 5-FU only, at all subsequent cycles.



Third episode: reduce docetaxel dose by 20%.




Stomatitis/mucositis grade 4




First episode: stop 5-FU only, at all subsequent cycles.



Second episode: reduce docetaxel dose by 20%.



For cisplatin and 5-fluorouracil dose adjustments, see the corresponding summary of product characteristics.



In the pivotal SCCHN studies patients who experienced complicated neutropenia (including prolonged neutropenia, febrile neutropenia, or infection), it was recommended to use G-CSF to provide prophylactic coverage (eg, day 6-15) in all subsequent cycles.



Special populations



Patients with hepatic impairment



Based on pharmacokinetic data with docetaxel at 100 mg/m² as single agent, patients who have both elevations of transaminase (ALT and/or AST) greater than 1.5 times the upper limit of the normal range (ULN) and alkaline phosphatase greater than 2.5 times the ULN, the recommended dose of docetaxel is 75 mg/m2 (see sections 4.4 and 5.2). For those patients with serum bilirubin > ULN and/or ALT and AST > 3.5 times the ULN associated with alkaline phosphatase > 6 times the ULN, no dose-reduction can be recommended and docetaxel should not be used unless strictly indicated.



In combination with cisplatin and 5-fluorouracil for the treatment of patients with gastric adenocarcinoma, the pivotal clinical study excluded patients with ALT and/or AST > 1.5 × ULN associated with alkaline phosphatase > 2.5 × ULN, and bilirubin > 1 x ULN; for these patients, no dose-reductions can be recommended and docetaxel should not be used unless strictly indicated. No data are available in patients with hepatic impairment treated by docetaxel in combination in the other indications.



Paediatric population



The safety and efficacy of TAXOTERE in nasopharyngeal carcinoma in children aged 1 month to less than 18 years have not yet been established.



There is no relevant use of TAXOTERE in the paediatric population in the indications breast cancer, non-small cell lung cancer, prostate cancer, gastric carcinoma and head and neck cancer, not including type II and III less differentiated nasopharyngeal carcinoma.



Elderly



Based on a population pharmacokinetic analysis, there are no special instructions for use in the elderly.



In combination with capecitabine, for patients 60 years of age or more, a starting dose reduction of capecitabine to 75% is recommended (see capecitabine summary of product characteristics).



4.3 Contraindications



Hypersensitivity to the active substance or to any of the excipients.



Patients with baseline neutrophil count of < 1,500 cells/mm3.



Patients with severe liver impairment (see sections 4.2 and 4.4).



Contraindications for other medicinal products also apply, when combined with docetaxel.



4.4 Special Warnings And Precautions For Use



For breast and non-small cell lung cancers, premedication consisting of an oral corticosteroid, such as dexamethasone 16 mg per day (e.g. 8 mg BID) for 3 days starting 1 day prior to docetaxel administration, unless contraindicated, can reduce the incidence and severity of fluid retention as well as the severity of hypersensitivity reactions. For prostate cancer, the premedication is oral dexamethasone 8 mg, 12 hours, 3 hours and 1 hour before the docetaxel infusion (see section 4.2).



Haematology



Neutropenia is the most frequent adverse reaction of docetaxel. Neutrophil nadirs occurred at a median of 7 days but this interval may be shorter in heavily pre-treated patients. Frequent monitoring of complete blood counts should be conducted on all patients receiving docetaxel. Patients should be retreated with docetaxel when neutrophils recover to a level



In the case of severe neutropenia (< 500 cells/mm3 for seven days or more) during a course of docetaxel therapy, a reduction in dose for subsequent courses of therapy or the use of appropriate symptomatic measures are recommended (see section 4.2).



In patients treated with docetaxel in combination with cisplatin and 5-fluorouracil (TCF), febrile neutropenia and neutropenic infection occurred at lower rates when patients received prophylactic G-CSF. Patients treated with TCF should receive prophylactic G-CSF to mitigate the risk of complicated neutropenia (febrile neutropenia, prolonged neutropenia or neutropenic infection). Patients receiving TCF should be closely monitored (see sections 4.2 and 4.8).



In patients treated with docetaxel in combination with doxorubicin and cyclophosphamide (TAC), febrile neutropenia and/or neutropenic infection occurred at lower rates when patients received primary G-CSF prophylaxis. Primary G-CSF prophylaxis should be considered in patients who receive adjuvant therapy with TAC for breast cancer to mitigate the risk of complicated neutropenia (febrile neutropenia, prolonged neutropenia or neutropenic infection). Patients receiving TAC should be closely monitored (see sections 4.2 and 4.8).



Hypersensitivity reactions



Patients should be observed closely for hypersensitivity reactions especially during the first and second infusions. Hypersensitivity reactions may occur within a few minutes following the initiation of the infusion of docetaxel, thus facilities for the treatment of hypotension and bronchospasm should be available. If hypersensitivity reactions occur, minor symptoms such as flushing or localised cutaneous reactions do not require interruption of therapy. However, severe reactions, such as severe hypotension, bronchospasm or generalised rash/erythema require immediate discontinuation of docetaxel and appropriate therapy. Patients who have developed severe hypersensitivity reactions should not be re-challenged with docetaxel.



Cutaneous reactions



Localised skin erythema of the extremities (palms of the hands and soles of the feet) with oedema followed by desquamation has been observed. Severe symptoms such as eruptions followed by desquamation which lead to interruption or discontinuation of docetaxel treatment were reported (see section 4.2).



Fluid retention



Patients with severe fluid retention such as pleural effusion, pericardial effusion and ascites should be monitored closely.



Patients with liver impairment



In patients treated with docetaxel at 100 mg/m2 as single agent who have serum transaminase levels (ALT and/or AST) greater than 1.5 times the ULN concurrent with serum alkaline phosphatase levels greater than 2.5 times the ULN, there is a higher risk of developing severe adverse reactions such as toxic deaths including sepsis and gastrointestinal haemorrhage which can be fatal, febrile neutropenia, infections, thrombocytopenia, stomatitis and asthenia. Therefore, the recommended dose of docetaxel in those patients with elevated liver function test (LFTs) is 75 mg/m2 and LFTs should be measured at baseline and before each cycle (see section 4.2).



For patients with serum bilirubin levels > ULN and/or ALT and AST > 3.5 times the ULN concurrent with serum alkaline phosphatase levels > 6 times the ULN, no dose-reduction can be recommended and docetaxel should not be used unless strictly indicated.



In combination with cisplatin and 5-fluorouracil for the treatment of patients with gastric adenocarcinoma, the pivotal clinical study excluded patients with ALT and/or AST > 1.5 × ULN associated with alkaline phosphatase > 2.5 × ULN, and bilirubin > 1 x ULN; for these patients, no dose-reductions can be recommended and docetaxel should not be used unless strictly indicated. No data are available in patients with hepatic impairment treated by docetaxel in combination in the other indications.



Patients with renal impairment



There are no data available in patients with severely impaired renal function treated with docetaxel.



Nervous system



The development of severe peripheral neurotoxicity requires a reduction of dose (see section 4.2).



Cardiac toxicity



Heart failure has been observed in patients receiving docetaxel in combination with trastuzumab, particularly following anthracycline (doxorubicin or epirubicin)-containing chemotherapy. This may be moderate to severe and has been associated with death (see section 4.8).



When patients are candidates for treatment with docetaxel in combination with trastuzumab, they should undergo baseline cardiac assessment. Cardiac function should be further monitored during treatment (e.g. every three months) to help identify patients who may develop cardiac dysfunction. For more details see summary of product characteristics of trastuzumab.



Others



Contraceptive measures must be taken by both men and women during treatment and for men at least 6 months after cessation of therapy (see section 4.6).



Additional cautions for use in adjuvant treatment of breast cancer



Complicated neutropenia



For patients who experience complicated neutropenia (prolonged neutropenia, febrile neutropenia or infection), G-CSF and dose reduction should be considered (see section 4.2).



Gastrointestinal reactions



Symptoms such as early abdominal pain and tenderness, fever, diarrhoea, with or without neutropenia, may be early manifestations of serious gastrointestinal toxicity and should be evaluated and treated promptly.



Congestive heart failure (CHF)



Patients should be monitored for symptoms of congestive heart failure during therapy and during the follow up period. In patients treated with the TAC regimen for node positive breast cancer, the risk of CHF has been shown to be higher during the first year after treatment (see sections 4.8 and 5.1).



Leukaemia



In the docetaxel, doxorubicin and cyclophosphamide (TAC) treated patients, the risk of delayed myelodysplasia or myeloid leukaemia requires haematological follow-up.



Patients with 4+ nodes



As the benefit observed in patient with 4+ nodes was not statistically significant on disease-free survival (DFS) and overall survival (OS), the positive benefit/risk ratio for TAC in patients with 4+ nodes was not fully demonstrated at the final analysis (see section 5.1).



Elderly



There are limited data available in patients > 70 years of age on docetaxel use in combination with doxorubicin and cyclophosphamide.



Of the 333 patients treated with docetaxel every three weeks in a prostate cancer study, 209 patients were 65 years of age or greater and 68 patients were older than 75 years. In patients treated with docetaxel every three weeks, the incidence of related nail changes occurred at a rate



Among the 300 (221 patients in the phase III part of the study and 79 patients in the phase II part) patients treated with docetaxel in combination with cisplatin and 5-fluorouracil in the gastric cancer study, 74 were 65 years of age or older and 4 patients were 75 years of age or older. The incidence of serious adverse events was higher in the elderly patients compared to younger patients. The incidence of the following adverse events (all grades): lethargy, stomatitis, neutropenic infection occurred at rates



Elderly patients treated with TCF should be closely monitored.



Excipients



This medicinal product contains 50 vol % ethanol (alcohol), i.e. up to 3.16 g (4 ml) per vial, equivalent to 80 ml of beer or 33 ml wine per vial.



Harmful for those suffering from alcoholism.



To be taken into account in pregnant or breast-feeding women, children and high-risk groups such as patients with liver disease, or epilepsy.



The amount of alcohol in this medicinal product may alter the effects of other medicinal products.



The amount of alcohol in this medicinal product may impair the patients ability to drive or use machines.



4.5 Interaction With Other Medicinal Products And Other Forms Of Interaction



In vitro studies have shown that the metabolism of docetaxel may be modified by the concomitant administration of compounds which induce, inhibit or are metabolised by (and thus may inhibit the enzyme competitively) cytochrome P450-3A such as ciclosporine, terfenadine, ketoconazole, erythromycin and troleandomycin. As a result, caution should be exercised when treating patients with these medicinal products as concomitant therapy since there is a potential for a significant interaction.



Docetaxel is highly protein bound (> 95%). Although the possible in vivo interaction of docetaxel with concomitantly administered medicinal product has not been investigated formally, in vitro interactions with tightly protein-bound agents such as erythromycin, diphenhydramine, propranolol, propafenone, phenytoin, salicylate, sulfamethoxazole and sodium valproate did not affect protein binding of docetaxel. In addition, dexamethasone did not affect protein binding of docetaxel. Docetaxel did not influence the binding of digitoxin.



The pharmacokinetics of docetaxel, doxorubicin and cyclophosphamide were not influenced by their co-administration. Limited data from a single uncontrolled study were suggestive of an interaction between docetaxel and carboplatin. When combined to docetaxel, the clearance of carboplatin was about 50% higher than values previously reported for carboplatin monotherapy.



Docetaxel pharmacokinetics in the presence of prednisone was studied in patients with metastatic prostate cancer. Docetaxel is metabolised by CYP3A4 and prednisone is known to induce CYP3A4. No statistically significant effect of prednisone on the pharmacokinetics of docetaxel was observed.



Docetaxel should be administered with caution in patients concomitantly receiving potent CYP3A4 inhibitors (e.g. protease inhibitors like ritonavir, azole antifungals like ketoconazole or itraconazole). A drug interaction study performed in patients receiving ketoconazole and docetaxel showed that the clearance of docetaxel was reduced by half by ketoconazole, probably because the metabolism of docetaxel involves CYP3A4 as a major (single) metabolic pathway. Reduced tolerance of docetaxel may occur, even at lower doses.



4.6 Pregnancy And Lactation



There is no information on the use of docetaxel in pregnant women. Docetaxel has been shown to be both embryotoxic and foetotoxic in rabbits and rats, and to reduce fertility in rats. As with other cytotoxic medicinal products, docetaxel may cause foetal harm when administered to pregnant women. Therefore, docetaxel must not be used during pregnancy unless clearly indicated.



Women of childbearing potential /contraception:



Women of childbearing age receiving docetaxel should be advised to avoid becoming pregnant, and to inform the treating physician immediately should this occur.



An effective method of contraception should be used during treatment.



In non clinical studies, docetaxel has genotoxic effects and may alter male fertility (see section 5.3). Therefore, men being treated with docetaxel are advised not to father a child during and up to 6 months after treatment and to seek advice on conservation of sperm prior to treatment.



Lactation:



Docetaxel is a lipophilic substance but it is not known whether it is excreted in human milk. Consequently, because of the potential for adverse reactions in nursing infants, breast feeding must be discontinued for the duration of docetaxel therapy.



4.7 Effects On Ability To Drive And Use Machines



No studies on the effects on the ability to drive and use machines have been performed.



4.8 Undesirable Effects



The adverse reactions considered to be possibly or probably related to the administration of docetaxel have been obtained in:



• 1312 and 121 patients who received 100 mg/m² and 75 mg/m² of docetaxel as a single agent respectively.



• 258 patients who received docetaxel in combination with doxorubicin.



• 406 patients who received docetaxel in combination with cisplatin.



• 92 patients treated with docetaxel in combination with trastuzumab.



• 255 patients who received docetaxel in combination with capecitabine.

These reactions were described using the NCI Common Toxicity Criteria (grade 3 = G3; grade 3-4 = G3/4; grade 4 = G4), the COSTART and the MedDRA terms. Frequencies are defined as: very common (



Within each frequency grouping, undesirable effects are presented in order of decreasing seriousness.



The most commonly reported adverse reactions of docetaxel alone are: neutropenia (which was reversible and not cumulative; the median day to nadir was 7 days and the median duration of severe neutropenia (< 500 cells/mm3) was 7 days), anaemia, alopecia, nausea, vomiting, stomatitis, diarrhoea and asthenia. The severity of adverse events of docetaxel may be increased when docetaxel is given in combination with other chemotherapeutic agents.



For combination with trastuzumab, adverse events (all grades) reported in



For combination with capecitabine, the most frequent treatment-related undesirable effects (



The following adverse reactions are frequently observed with docetaxel:



Immune system disorders



Hypersensitivity reactions have generally occurred within a few minutes following the start of the infusion of docetaxel and were usually mild to moderate. The most frequently reported symptoms were flushing, rash with or without pruritus, chest tightness, back pain, dyspnoea and fever or chills. Severe reactions were characterised by hypotension and/or bronchospasm or generalized rash/erythema (see section 4.4).



Nervous system disorders



The development of severe peripheral neurotoxicity requires a reduction of dose (see sections 4.2 and 4.4). Mild to moderate neuro-sensory signs are characterised by paresthesia, dysesthesia or pain including burning. Neuro-motor events are mainly characterised by weakness.



Skin and subcutaneous tissue disorders



Reversible cutaneous reactions have been observed and were generally considered as mild to moderate. Reactions were characterised by a rash including localised eruptions mainly on the feet and hands (including severe hand and foot syndrome), but also on the arms, face or thorax, and frequently associated with pruritus. Eruptions generally occurred within one week after the docetaxel infusion. Less frequently, severe symptoms such as eruptions followed by desquamation which rarely lead to interruption or discontinuation of docetaxel treatment were reported (see sections 4.2 and 4.4). Severe nail disorders are characterised by hypo- or hyperpigmentation and sometimes pain and onycholysis.



General disorders and administration site conditions



Infusion site reactions were generally mild and consisted of hyper pigmentation, inflammation, redness or dryness of the skin, phlebitis or extravasation and swelling of the vein.



Fluid retention includes events such as peripheral oedema and less frequently pleural effusion, pericardial effusion, ascites and weight gain. The peripheral oedema usually starts at the lower extremities and may become generalised with a weight gain of 3 kg or more. Fluid retention is cumulative in incidence and severity (see section 4.4).

Nervous system disorders



Reversibility data are available among 35.3% of patients who developed neurotoxicity following docetaxel treatment at 100 mg/m² as single agent. The events were spontaneously reversible within 3 months.



Skin and subcutaneous tissue disorders



Very rare: one case of alopecia non-reversible at the end of the study. 73% of the cutaneous reactions were reversible within 21 days.



General disorders and administration site conditions



The median cumulative dose to treatment discontinuation was more than 1,000 mg/m2 and the median time to fluid retention reversibility was 16.4 weeks (range 0 to 42 weeks). The onset of moderate and severe retention is delayed (median cumulative dose: 818.9 mg/m2) in patients with premedication compared with patients without premedication (median cumulative dose: 489.7 mg/m2); however, it has been reported in some patients during the early courses of therapy.
