Prevalin relieves the symptoms of hay fever in the nose and eyes without causing side effects.
Once shaken Prevalin becomes a liquid that can be easily sprayed into the nose. It then forms a stable and impermeable microgel barrier blocking the allergens from irritating the nasal mucosa and causing symptoms.
Prevalin's triple action formula ensures an effective treatment preventing pollen from irritating the mast cells and releasing histamines:
Prevalin's patented formula contains specific ingredients that uniquely deactivate pollen in the nose so it cannot irritate the nasal mucosa.
Prevalin's microgel formula then forms an impermeable layer on the mucosa for protection against pollen irritation.
Prevalin also stimulates the clearance of pollen from the body.
