Name: AH-Chew II

What is AH-Chew II (chlorpheniramine, methscopolamine, and phenylephrine)?

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

Methscopolamine reduces the secretions of certain organs in the body.

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

Chlorpheniramine, methscopolamine, and phenylephrine is a combination medicine used to treat runny or stuffy nose, sneezing, itching, watery eyes, and sinus congestion caused by allergies, the common cold, or the flu.

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