Nasaleze Allergy Blocker Nasal Spray x800ml: Your Shield Against Allergies

Nasaleze Allergy Blocker Nasal Spray x800ml: Your Shield Against Allergies

Nasaleze Allergy Blocker is a preventive nasal spray designed to combat hay fever and allergies effectively. It works by reducing sneezing, runny nose, and sinus congestion caused by allergens. This innovative product is used proactively before exposure to allergen-rich environments, preventing contact between allergens and the nasal mucosa, thus mitigating the body's allergic response.

Key Features:

  • Protective Barrier: Upon contact with the nasal mucosa, the powder particles in Nasaleze Allergy Blocker form a gel-like protective barrier. This barrier shields and isolates the mucosa from airborne allergen particles, providing relief from allergic symptoms.
  • Natural Composition: Formulated with natural inert cellulose powder of plant origin and mint, Nasaleze Allergy Blocker offers a safe and effective solution for allergy prevention.

Usage Instructions:

  1. Preparation: Blow your nose to clear the nasal passages.
  2. Pre-Spray (First Use Only): Open the cap, shake the bottle, and spray a small amount into the air to release pressure. This step is only necessary for the first use.
  3. Application: Place the spray nozzle at the entrance of each nostril and spray 1-2 times. Inhale gently.
  4. Post-Spray: Repeat the spraying process after each nose blow to maintain effectiveness.


  • Spray Nasaleze Allergy Blocker 2 to 3 times daily for optimal protection against allergens.
