What is chlorpheniramine, hydrocodone, and pseudoephedrine?

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.

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

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

Chlorpheniramine, hydrocodone, and pseudoephedrine is a combination medicine used to treat runny or stuffy nose, sneezing, cough, and sinus congestion caused by allergies or the common cold.

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