Zyrtec 10mg Tablet 10'S is a member of the anti-histamine or anti-allergic medication class. Cetirizine, which is generally used to treat different allergies, is present. An allergic reaction is an immune system reaction to outside substances that are usually not detrimental to your body. These alien substances are referred to as "allergens." The severity of allergies varies from person to person. Some people may have dietary allergies as well as seasonal allergies like hay fever. Others might, however, have allergies to pet dander or pollen. Cetirizine (anti-histamine), found in Zyrtec 10mg Tablet 10'S, is used to treat allergies because it inhibits the actions of the chemical messenger "histamine," which is normally implicated in allergic reactions. Additionally, Zyrtec Syrup 60 ml cures seasonal allergic rhinitis (hay fever) all year long.Disclaimer:For more information contact your physician.
