If you have never heard of Claritin it is simply an allergy drug that people take to combat allergy symptoms. The active ingredient inside Claritin is Loratadine which is an antihistamine and helps suppress normal allergy symptoms.

Claritin and Claritin D are the brand names of two antihistamines taken by millions of people suffering from allergies. The active ingredient, Loratadine, was developed by the drug company Schering-Plough as a non-sedating antihistamine. Loratadine was one of the first non-sedating antihistamines approved by the FDA for use. While Claritin and Claritin D are highly effective for most people, some people experience side effects ranging from dry mouth to severe reactions.

FDA has approved Claritin (loratadine) as an over-the-counter (OTC) allergy drug product. Previously available only as a prescription drug, Claritin is approved for seasonal allergic rhinitis -- a condition that causes runny nose, nasal congestion, sneezing, and itchy nose, throat, eyes, and ears.
