Claritin or its generic alternative Loratadine is an over-the-counter antihistamine medication that works well to relieve allergy symptoms. It may be used alone or in combination with other medications to treat hives and chronic skin reactions. Claritin is indicated for the management of hay fever and other upper respiratory allergies.

Claritin belongs to a class of drugs known as antihistamine which used to reduce the effects of histamine, a natural chemical produced in the body. Histamine is responsible for causing symptoms such as sneezing, itching, watery eyes, and runny nose.
