Nasonex Aqueous Nasal Spray is a topical corticosteroid used to manage allergic rhinitis and nasal polyps in adults and children over two years old. Each spray delivers a precise dose of mometasone furoate monohydrate (50 mcg) directly into the nasal cavity, where it reduces inflammation and prevents allergic flare-ups. It is designed for daily use, helping to relieve symptoms such as nasal congestion, itching, sneezing, and mucus buildup. Nasonex is available in bottles containing 60 or 120 metered sprays, providing up to one month of consistent treatment depending on dosage and frequency.
