What is Nasonex?
Nasonex nasal spray contains the active ingredient mometasone furoate, which is steroid (corticosteroid). It is used to treat symptoms of an allergic reaction or hay fever, such as sneezing, a blocked or runny nose and itching. Nasonex is available as a generic version, known as Mometasone nasal spray.
How does Nasonex work?
Nasonex works by releasing mometasone into the cells in the nasal passage. This prevents them from releasing chemicals that cause symptoms of allergy. Nasonex works in this way to reduce irritation and swelling which relieves other symptoms such as sneezing, itchiness or a blocked nose.
