ZYRTEC Allergen Shield

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 to block allergens.

Protective barrier to block allergens

How does it work?

ZYRTEC™ Allergen Shield Spray is a gentle fine mist that turns into a gel in the nose. This gel creates a physical barrier in the nasal passageway that:

  • Traps: Allergen particles are trapped by a physical barrier that forms in minutes.

  • Blocks: Future allergens are blocked from contacting the nasal passageway.

  • Removes: Trapped allergens are removed naturally by the body.
