Claritin Clear (Loratadine): Allergy Relief & How It Works

Claritin Clear (loratadine) is an antihistamine used to treat allergy symptoms such as sneezing, runny nose, watery eyes, and itching of the eyes, nose, or throat. It is also used to treat hives. Loratadine works by blocking the effects of histamine, a natural substance that is released when the body's immune system reacts to an allergen.
