Pharmaniaga Allerstop Nasal Spray provides mechanical protection for the nasal mucosa, creating a barrier against allergens like pollen, dust, and other antigens. It is designed to help manage allergic rhinitis, either as a preventive measure before pollen season or at the first signs of symptoms. The spray works by cleansing the nasal cavities, removing antigens and pollen residues, and forming a protective layer on the nasal mucosa. This barrier prevents allergens from contacting nasal cells, reducing the risk of symptom recurrence and offering effective relief and protection.
