Zyrtec (cetirizine) is what type of medication?

Explanation:
Cetirizine is best described as an antihistamine. When an allergic reaction occurs, histamine is released and binds to H1 receptors in tissues, leading to sneezing, itching, runny nose, and swelling. An antihistamine like cetirizine blocks those H1 receptors, reducing the effects of histamine and easing allergy symptoms. Zyrtec is a second-generation antihistamine, which generally causes less drowsiness than older options because it crosses into the brain less. It’s used in veterinary contexts mainly for allergic symptoms such as dermatitis or rhinitis, not for treating fungal infections, inflammation from other causes, or stimulating appetite.
