What is dexbrompheniramine, hydrocodone, and phenylephrine (Cytuss-HC NR, H-C Tussive-NR, Histussin HC)?

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

Hydrocodone is a narcotic cough suppressant.

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

The combination of dexbrompheniramine, hydrocodone, and phenylephrine is used to treat nasal congestion, sneezing, runny nose, itchy or water eyes, and cough caused by allergies or the common cold.

Dexbrompheniramine, hydrocodone, and phenylephrine may also be used for other purposes not listed in this medication guide.
