Acetaminophen is a pain reliever and fever reducer.

Dextromethorphan is a cough suppressant. It affects the cough reflex in the brain that triggers coughing.

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

Acetaminophen, dextromethorphan, and doxylamine is a combination medicine used to treat headache, fever, body aches, cough, runny nose, sneezing, and sore throat caused by allergies, the common cold, or the flu.

acetaminophen, dextromethorphan, and doxylamine will not treat a cough that is caused by smoking, asthma, or emphysema.
