Overview
Cetirizine is a second-generation antihistamine commonly used in veterinary medicine to alleviate allergy symptoms in pets, including dogs and cats. It works by blocking the action of histamine, a substance in the body that causes allergic symptoms.

- Atopic dermatitis
- Allergic rhinitis
- Urticaria (hives)
