About Nasonex
Nasonex is a mometasone nasal spray for allergic rhinitis that moved from prescription to over-the-counter sale, one of a series of such switches Perrigo has acquired rights to as brands come off prescription. A prescription-to-pharmacy switch typically extends a brand's commercial life well beyond the expiry of its patents.
