Allergies Home > Clarinex

Clarinex helps relieve seasonal and indoor allergy symptoms, as well as chronic hives and itching. It works by blocking histamine -- a chemical in the body that causes sneezing, itching, and irritation when you come into contact with something you're allergic to. Clarinex does not, however, help clear nasal passages. Common side effects, while rare, include nausea, sore throat, and dry mouth.
