Chlorpheniramine

Chlorpheniramine (pronounced klor-fen-IR-a-meen) is an antihistamine used to relieve symptoms of allergy, hay fever, and the common cold. These symptoms include rash, watery eyes, itchy eyes, itchy nose, runny nose, and sneezing.

Etymology

The term "Chlorpheniramine" is derived from its chemical structure. The prefix "Chlor-" refers to the presence of a chlorine atom, while "pheniramine" is a class of antihistamines.

Usage

Chlorpheniramine works by blocking a certain natural substance (histamine) that your body makes during an allergic reaction. By blocking the effects of histamine, it can reduce allergy symptoms. It is also used to prevent motion sickness, to treat Parkinson's disease, and to induce sleep for those with sleep disorders.
