FastBlock® Allergy Relief is a fine-powder nasal spray that coats the allergy receptors in the nasal passages. This forms a protective barrier that blocks airborne allergens such as pollen, dust mites and animal dander—and stops allergies and hay fever where they start.
FastBlock® Allergy Relief is clinically proven to reduce:
• Itchy & Runny Nose
• Sinus Congestion
Unlike liquid nasal sprays or allergy drugs, FastBlock® Allergy Relief is safe, and does not cause drowsiness, irritate the nasal passages, or cause unpleasant side effects. It is drug-free and non-habit-forming, and is clinically proven to deliver fast, effective protection against hay fever and other airborne allergens.
