Prevalin Allergy Nasal Spray works by creating a barrier on the nasal lining.
Instead of treating hay fever symptoms once they have set in, Prevalin tackles the root cause of hay fever before full blown symptoms even occur. With its unique approach, Prevalin lines the inside of the nose, deactivating pollen and getting to the root of the problem - addressing all significant hay fever symptoms, without the side-effects.
Prevalin allergy nasal spray is a unique formulation that changes from a gel to liquid state easily after shaking; this makes it easier to spray into the nose.
