Mintuss DR Syrup

Name: Mintuss DR Syrup


Rx Only


A persistent cough may be a sign of a serious condition. If cough persists for more than one week, tends to recur, or is accompanied by fever, rash, or persistent headache, consult a physician. Do not take this product for persistent or chronic cough such as occurs with smoking, asthma, or emphysema, or if cough is accompanied by excessive phlegm (mucus) unless directed by a physician.

Hypertensive crisis can occur with concurrent use of phenylephrine and monoamine oxidase (MAO) inhibitors (or for 14 days after stopping MAOI therapy), indomethacin or with beta-blockers and methyldopa. If a hypertensive crisis occurs, these drugs should be discontinued, and therapy to lower blood pressure should be instituted immediately. Fever should be managed by external cooling.

Antihistamines may produce drowsiness or excitation, particularly in children and elderly patients. Do no exceed recommended dosage. Especially in infants and small children, antihistamines in overdosage may cause hallucinations, convulsions, and death.



Because of its antihistamine component, Mintuss™ DR Syrup should be used with caution in patients with a history of bronchial asthma, gastrointestinal obstruction, or urinary bladder neck obstruction. Because of its sympathomimetic component, Mintuss™ DR Syrup should be used judiciously and sparingly in patients with hypertension, diabetes, heart disease, increased intraocular pressure, hyperthyroidism, or prostatic hypertrophy. Sympathomimetics may produce central nervous system stimulation with convulsions or cardiovascular collapse with accompanying hypotension.

Information for Patients

Antihistamines may impair mental and/or physical abilities required for the performance of potentially hazardous tasks, such as driving a vehicle or operating machinery. Patients should be cautioned accordingly.

Stimulants, such as phenylephrine, are banned and tested for by the U.S. Olympic Committee (USOC) and the National Collegiate Athletic Association (NCAA.)

Drug Interactions

Antihistamines have additive effects with alcohol and other CNS depressants (hypnotics, sedatives, tranquilizers, antianxiety agents, etc.) When such combined therapy is contemplated, the dose of one or both agents should be reduced. The use of phenylephrine with other sympathomimetic amines and MAO inhibitors (or for 14 days after stopping MAOI therapy) may produce an additive elevation of blood pressure. MAO inhibitors (or for 14 days after stopping MAOI therapy) may prolong the anticholinergic effects of antihistamines (See WARNINGS).
