Histex-AC

Generic name: Codeine, Phenylephrine, And Triprolidine
Drug class: Upper respiratory combinations

Usage of Histex-AC

Triprolidine 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.

Codeine is a narcotic 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).

Histex-AC is a combination medicine used to treat runny or stuffy nose, sneezing, itching, watery eyes, cough, and sinus congestion caused by allergies, the common cold, or the flu.

Histex-AC will not treat a cough that is caused by smoking, asthma, or emphysema.

Histex-AC may also be used for purposes not listed in this medication guide.
