What is acetaminophen, dextromethorphan, pseudoephedrine, and pyrilamine (Robitussin Night Relief)?
Pyrilamine is an antihistamine that reduces the effects of natural chemical histamine in the body. Histamine can produce symptoms such as sneezing, runny nose, and watery eyes.
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.
