Table of contents:

Zyrtec is generically known as Cetirizine, an over-the-counter medication used to treat allergies and other related conditions. It belongs to a class drug antihistamine. It works by blocking the action of histamines that are released during an allergic response. When histamine binds to its receptors, it causes inflammation and other symptoms of an allergic reaction.
