Indications

Nasonex nasal spray treats the nasal symptoms of allergic rhinitis in patients aged 2 years and older, and it treats nasal congestion associated with seasonal allergic rhinitis in this same age group. In patients 12 years of age and older, it can also be used to prevent seasonal allergic rhinitis before symptoms begin. For adults 18 years and older, it is indicated for the treatment of nasal polyps.

⚠️ Always consult a registered physician before taking any medicine.

Pharmacology

Mometasone Furoate is a corticosteroid with anti-inflammatory activity. The exact mechanism of corticosteroid action in allergic rhinitis is not fully understood. Corticosteroids have been shown to affect a wide range of cell types (such as mast cells, eosinophils, neutrophils, macrophages, and lymphocytes) and mediators (such as histamine, eicosanoids, leukotrienes, and cytokines) that are involved in inflammation.

Pregnancy & Breastfeeding

Pregnancy Category C. Well-controlled studies in pregnant women are lacking. As with other corticosteroids, Mometasone Furoate should be used in pregnancy only if the potential benefit outweighs the potential risk to the unborn baby. Whether it passes into human breast milk is not known, but since other corticosteroids do, caution is advised when giving Mometasone Furoate Nasal Spray to breastfeeding mothers.

⚠️ Talk to your doctor before taking any medicine during pregnancy or while breastfeeding.
