Brompheniramine is an antihistamine that reduces the effects of natural chemical histamine in the body. Histamine can produce symptoms of sneezing, itching, watery eyes, and runny nose.

Dextromethorphan is a cough suppressant. It affects the signals in the brain that trigger cough reflex.

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

Brompheniramine, dextromethorphan, and pseudoephedrine is a combination medicine used to treat cough, runny or stuffy nose, sneezing, itching, and watery eyes caused by allergies, the common cold, or the flu.

This medicine will not treat a cough that is caused by smoking, asthma, or emphysema.

Brompheniramine, dextromethorphan, and pseudoephedrine may also be used for purposes not listed in this medication guide.

Drinking alcohol can increase certain side effects of brompheniramine, dextromethorphan, and pseudoephedrine.

Ask a doctor or pharmacist before using any other cold, cough, allergy, or sleep medicine. Antihistamines and cough suppressants are contained in many combination medicines. Taking certain products together can cause you to get too much of a certain drug. Check the label to see if a medicine contains an antihistamine or cough suppressant.

This medication may cause blurred vision and may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be alert and able to see clearly.

Avoid becoming overheated or dehydrated during exercise and in hot weather. Brompheniramine and pseudoephedrine can decrease sweating and you may be more prone to heat stroke.
