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.
