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

Dihydrocodeine is in a group of drugs called narcotics and is similar to codeine. Dihydrocodeine is a cough suppressant that affects 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).

The combination of brompheniramine, dihydrocodeine, and pseudoephedrine is used to treat cough, sneezing, itching, watery eyes, runny nose, stuffy nose, and sinus congestion caused by allergies, the common cold, or the flu.

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