Acetaminophen, diphenhydramine, and dextromethorphan 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, for instance, is a pain reliever and fever reducer. As for Diphenhydramine, it is an antihistamine that reduces the effects of the natural chemical histamine in the body.
