descriptionsCetirizine Zyrtec belongs to a class of allergy medications called antihistamines or histamine receptor blockers. Zyrtec is used to treat allergic symptoms like tearing and redness of the eyes running and red nose and hives including itching skin rashes and insect bites. Cetirizine blocks the actions of the naturally occurring chemicals called histamines in the body. Histamines are responsible for promoting symptoms of allergy when released by allergic reactions in the body. Cetirizine is one of those new antihistamines called non-sedating antihistamines because they cause fewer side effects like drowsiness and dizziness. To know more about the uses of Zyrtec you will need to speak to your doctor or pharmacist.
