Hayfever & allergy treatment

Zirtek is a very effective symptomatic treatment for hay fever and other allergies that contain the active ingredient cetirizine. When our bodies are exposed to an allergen, a chemical known as histamine is released, which indirectly leads to the onset of allergic symptoms like congestion and watery eyes in hay fever sufferers. Cetirizine works by stopping the action of histamine, which in turn prevents the onset of allergic symptoms.
