Zyrtec 

Urticaria 

Cetirizine hydrochloride (marketed as Zyrtec, or Zirtek in the United Kingdom) is a medication used for the treatment of allergy, hayfever, angioedema, and hives. It is a second-generation H1-receptor antagonist antihistamine and works by blocking H1 histamine receptors. It is a major metabolite of hydroxyzine, and has the same basic side effects.

Urticaria or hives is a relatively common form of allergic reaction that causes raised red skin welts that range upwards from 5 mm (about a 1/4 inch) in diameter, itch severely, and often have a pale border. Urticaria is caused by direct contact with an allergenic substance (generally a plant, such as poison ivy), or an immune response to food or some other allergen. Hives can also be caused by stress.
