What is NoHist-A?

Chlorpheniramine and phenyltoloxamine are antihistamines that reduce the effects of natural chemical histamine in the body. Histamine can produce symptoms of sneezing, itching, watery eyes, and runny nose.

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

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

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

NoHist-A may also be used for purposes not listed in this medication guide.
