Product Overview

Each allergy medicine tablet contains 10 mg Cetirizine HCl antihistamine to relieve your worst allergy symptoms, indoors and out, for a full 24 hours. Zyrtec® tablets help relieve seasonal allergy and other upper respiratory allergy symptoms, including itchy eyes, sneezing, runny nose, itchy nose or throat, and more. These allergy relief medicine tablets help treat symptoms of pollen allergies & other outdoor seasonal allergies, as well as indoor allergies, such as dust allergies, pet allergies, and more. From the #1 allergist recommended brand among OTC oral antihistamines, this prescription-strength allergy medicine starts working hard at hour 1 and works twice as hard when you take it again the next day.

Get allergy relief that starts working faster than Claritin® on the first day you take it.*

Having allergies can be frustrating at times, whether they’re making your eyes itch, your nose run, or a combination of the two. So, it’s a relief to know that antihistamines can help relieve your symptoms.

Cetirizine Chemical Formula

Active Ingredient

Cetirizine HCl 10 mg (in each tablet)

When you have an allergic reaction, your immune system produces chemicals known as histamines to fight the allergen, and these are what cause your symptoms. Cetirizine helps relieve these symptoms by blocking the effects of histamines, so your symptoms don’t develop.
