The next generation of hay fever treatment
When to use Prevalin™
Use Prevalin™ at the first sign of hay fever to defuse pollen before full-blown
symptoms can develop.
Prevalin™ should be sprayed once or twice into each nostril
2 to 3 times a day, as it provides protection for 4 to 6 hours.
(Mucociliary clearance of the nose happens approximately every
6 hours as the body naturally gets rid of foreign particles in the nose).
