Loratadine (an antihistamine ) is the active ingredient in Claritin® Tablets, Claritin® RediTabs®, Claritin® Liqui-Gels®, Children’s Claritin® Chewables, Children’s Claritin® Syrup and Claritin® RediTabs® for Juniors. Claritin-D® contains two active ingredients: loratadine and pseudoephedrine (a nasal decongestant ).

The inactive ingredients differ in each form. See individual product pages for ingredient lists.

When you inhale an airborne allergen like those from pollen , mold spores, pet dander or mold , it triggers a complicated series of reactions in your immune system known as the “allergic cascade.” This cascade ultimately leads to the release of many mediators, including histamine , which are organic compounds in the body that can cause symptoms such as itchy nose or throat and swelling of nasal passages. Claritin® hinders the part of the allergic cascade, which relieves symptoms of allergic rhinitis , or “ hay fever .”
