Zyrtec Allergen Shield Spray is a drug-free nasal mist designed to help allergy sufferers stay one step ahead of allergy season. Unlike typical nasal sprays, Zyrtec Allergen Shield works by forming a lightweight protective barrier inside the nasal cavity. The protective gel barrier blocks allergens to help combat allergy symptoms before they start, when used before allergen exposure. The gentle nasal mist is formulated to block allergens in minutes, making it easy to use before allergen exposure at home, at work, outdoors, or while traveling. Because this allergen defense spray is drug-free, steroid-free, and contains a naturally derived ingredient (HPMC), it fits easily into your allergy care essentials. Each bottle provides up to 100 sprays, keeping you covered during allergy season. Scientifically proven, Zyrtec Allergen Shield Spray helps you take control of allergy season before or after symptoms strike. Does not contain cetirizine.
