Brompheniramine Maleate, Pseudoephedrine Hydrochloride and Dextromethorphan Hydrobromide

For relief of coughs and upper respiratory symptoms, including nasal congestion, associated with allergy or the common cold.

Hypersensitivity to any of the ingredients. Do not use in the newborn, in premature infants, in nursing mothers, or in patients with severe hypertension or severe coronary artery disease. Do not use dextromethorphan in patients receiving monoamine oxidase (MAOI) inhibitors ( see PRECAUTIONS – Drug Interactions ). Antihistamines should not be used to treat lower respiratory tract conditions including asthma.

Especially in infants and small children, antihistamines in overdosage may cause hallucinations, convulsions, and death. Antihistamines may diminish mental alertness. In the young child, they may produce excitation.

General Because of its antihistamine component, Brompheniramine Maleate, Pseudoephedrine Hydrochloride and Dextromethorphan Hydrobromide Oral Syrup should be used with caution in patients with a history of bronchial asthma, narrow angle glaucoma, gastrointestinal obstruction, or urinary bladder neck obstruction. Because of its sympathomimetic component, Brompheniramine Maleate, Pseudoephedrine Hydrochloride and Dextromethorphan Hydrobromide Oral Syrup should be used with caution in patients with diabetes, hypertension, heart disease, or thyroid disease. Information for Patients Patients should be warned about engaging in activities requiring mental alertness, such as driving a car or operating dangerous machinery. Drug Interactions Monoamine oxidase (MAO) inhibitors Hyperpyrexia, hypotension, and death have been reported coincident with the coadministration of MAO inhibitors and products containing dextromethorphan. In addition, MAO inhibitors prolong and intensify the anticholinergic (drying) effects of antihistamines and may enhance the effect of pseudoephedrine. Concomitant administration of Brompheniramine Maleate, Pseudoephedrine Hydrochloride and Dextromethorphan Hydrobromide Oral Syrup and MAO inhibitors should be avoided ( see CONTRAINDICATIONS ). Central Nervous System (CNS) depressants Antihistamines have additive effects with alcohol and other CNS depressants (hypnotics, sedatives, tranquilizers, antianxiety agents, etc.). Antihypertensive drugs Sympathomimetic may reduce the effects of antihypertensive drugs. Carcinogenesis, Mutagenesis, Impairment of Fertility Animal studies of Brompheniramine Maleate, Pseudoephedrine Hydrochloride and Dextromethorphan Hydrobromide Oral Syrup to assess the carcinogenic and mutagenic potential or the effect on fertility have not been performed. Pregnancy Teratogenic Effects Pregnancy Category C Animal reproduction studies have not been conducted with Brompheniramine Maleate, Pseudoephedrine Hydrochloride and Dextromethorphan Hydrobromide Oral Syrup. It is also not known whether Brompheniramine Maleate, Pseudoephedrine Hydrochloride and Dextromethorphan Hydrobromide Oral Syrup can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. It should be given to a pregnant woman only if clearly needed. Reproduction studies of brompheniramine maleate (a component of Brompheniramine Maleate, Pseudoephedrine Hydrochloride and Dextromethorphan Hydrobromide Oral Syrup) in rats and mice at doses up to 16 times the maximum human doses have revealed no evidence of impaired fertility or harm to the fetus. Nursing Mothers Because of the higher risk of intolerance of antihistamines in small infants generally, and in newborns and prematures in particular, Brompheniramine Maleate, Pseudoephedrine Hydrochloride and Dextromethorphan Hydrobromide Oral Syrup is contraindicated in nursing mothers. Pediatric Use Safety and effectiveness in pediatric patients below the age of 6 months have not been established ( see DOSAGE AND ADMINISTRATION ). Geriatric Use Clinical studies of Brompheniramine Maleate, Pseudoephedrine Hydrochloride and Dextromethorphan Hydrobromide Oral Syrup did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. However, antihistamines are more likely to cause dizziness, sedation, and hypotension in elderly patients. The elderly are also more likely to experience adverse reactions to sympathomimetics. 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.

The most frequent adverse reactions to Brompheniramine Maleate, Pseudoephedrine Hydrochloride and Dextromethorphan Hydrobromide Oral Syrup are: sedation; dryness of mouth, nose and throat; thickening of bronchial secretions; dizziness. Other adverse reactions may include: Dermatologic: Urticaria, drug rash, photosensitivity, pruritus. Cardiovascular System: Hypotension, hypertension, cardiac arrhythmias, palpitation. CNS: Disturbed coordination, tremor, irritability, insomnia, visual disturbances, weakness, nervousness, convulsions, headache, euphoria, and dysphoria. G.U. System: Urinary frequency, difficult urination. G.I. System: Epigastric discomfort, anorexia, nausea, vomiting, diarrhea, constipation. Respiratory System: Tightness of chest and wheezing, shortness of breath. Hematologic System: Hemolytic anemia, thrombocytopenia, agranulocytosis.
