Why chose Zyrtec? Having allergies can be frustrating at times. When you have an allergic reaction, your immune system produces chemicals known as histamines to fight the allergen, and these are what cause your symptoms. Cetirizine hydrochloride, the active ingredient in Zyrtec, helps relieve these symptoms by blocking the effects of histamines, so your symptoms don’t develop. Understanding types of allergies Seasonal Allergies Are Common, But That Doesn’t Mean You Need to Suffer. Seasonal allergies can occur at any time of the year but are most common in the spring and summer. Plants release tiny grains, which we know as pollen, to fertilize other plants. When we breathe in those pollens, the body’s natural reaction is to attack, which causes irritation and inflammation within our sinuses and nasal cavities. ZYRTEC works fast* to relieve your allergy symptoms. If you suffer from allergies year-round, you could be experiencing perennial (indoor) allergies. Dust mites are typically found in upholstered furniture, carpets & bedding. Pet allergies stem from proteins contained in an animal’s dander, or dead skin cells. Mold reproduces through tiny, airborne spores. Indoor molds grow in damp areas, like the bathtub or shower.
