What is carbetapentane, phenylephrine, and pyrilamine?

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

Phenylephrine is a decongestant that shrinks blood vessels in the nasal passages. Dilated blood vessels can cause nasal congestion (stuffy nose).

Pyrilamine 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.

The combination of carbetapentane, phenylephrine, and pyrilamine is used to treat runny or stuffy nose, sneezing, itching, watery eyes, cough, and sinus congestion caused by allergies, the common cold, or the flu.

Carbetapentane, phenylephrine, and pyrilamine may also be used for purposes not listed in this medication guide.
