Why is this medication prescribed?

Chlorpheniramine is an antihistamine medication commonly used to relieve symptoms of allergic conditions such as hay fever (allergic rhinitis), hives (urticaria), allergic conjunctivitis, and allergic reactions to insect bites or stings. It works by blocking the action of histamine, a substance in the body that causes allergic symptoms like sneezing, itching, watery eyes, and runny nose.
