Cetirizine dihydrochloride, the active ingredient of the tablets is an antihistamine. It blocks the
effects of a substance called histamine which occurs naturally in the body. Histamine is involved in allergic reactions.
Zirtek Allergy Relief is used to treat people who have hay fever (seasonal allergic rhinitis), year
round allergies such as dust or pet allergies (perennial allergic rhinitis) and urticaria (swelling,
redness and itchiness of the skin).
Antihistamines like Zirtek Allergy Relief relieve the unpleasant symptoms and discomfort
associated with these conditions, such as sneezing, irritated, runny and blocked up nose, itchy,
red and watering eyes and skin rashes.
