What is Robitussin Night Relief (Apap/Dextromethorphan/Pse/Pyrilamine)?

Acetaminophen is a pain reliever and fever reducer.
Pyrilamine is an antihistamine that reduces the natural chemical histamine in the body. Histamine can produce symptoms such as sneezing, runny nose, and watery eyes.
Dextromethorphan is a cough suppressant. It affects the cough reflex in the brain that triggers coughing.
Pseudoephedrine is a decongestant that shrinks blood vessels in the nasal passages. Dilated blood vessels can cause nasal congestion (stuffy nose).
The combination of acetaminophen, dextromethorphan, pseudoephedrine, and pyrilamine is used to treat runny or stuffy nose, sinus congestion, cough, and pain or fever caused by the common cold or flu.
Dextromethorphan will not treat a cough that is caused by smoking.
Acetaminophen, dextromethorphan, pseudoephedrine, and pyrilamine may also be used for other purposes not listed in this medication guide.
