Dexchlorpheniramine is an antihistamine used to relieve symptoms of allergy, hay fever, and the common cold. These symptoms include rash, itchy eyes/nose/throat/skin, cough, and sneezing. Dexchlorpheniramine works by blocking a certain natural substance (histamine) that your body makes during an allergic reaction. It helps dry up some body fluids to relieve symptoms such as watery eyes and runny nose.
