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:

  • Sneezing
  • 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. Safe for adults and children 18 months or older, including pregnant and nursing women. *These statements have not been evaluated by the Food and Drug Administration.
