Ingredients Spotlight

Active Ingredient

Cetirizine HCl 10 mg (in each tablet)

When you have an allergic reaction, your immune system releases chemicals called histamines to fight the allergen, which leads to various allergy symptoms. Cetirizine helps relieve these allergy symptoms by blocking the effects of histamines, reducing the severity of your symptoms.
