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

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

Chlorpheniramine and codeine will not treat a cough that is caused by smoking, asthma, or emphysema.

Chlorpheniramine and codeine may also be used for other purposes not listed in this medication guide.
