Overview
Cetirizine 10mg is a second-generation antihistamine commonly used off-label in veterinary medicine to manage allergic conditions in dogs and cats. It works by selectively blocking histamine H₁ receptors, helping to alleviate symptoms such as itching, sneezing, and skin irritation. Cetirizine is less sedating than first-generation antihistamines, making it a preferred option for pets requiring long-term allergy management without significant drowsiness.

- Non-sedating formula suitable for daytime use
- May reduce reactions to insect bites, vaccines, and environmental allergens
- Can be used as adjunctive therapy with corticosteroids to reduce steroid dosage
