What is Nasonex 24HR?

Nasonex is a prescription intranasal corticosteroid used to treat the nasal symptoms of seasonal and perennial allergic rhinitis—including congestion, runny nose, sneezing, and nasal itching. It's also approved to treat nasal polyps in adults. Mometasone works locally in the nasal passages to reduce the inflammation driven by allergic exposure to pollens, dust mites, pet dander, and mold. It's used as one or two sprays in each nostril once daily and typically requires several days of consistent use before full symptom relief is achieved. Systemic absorption is minimal, keeping side effects low.

Intranasal corticosteroid activity

Suppresses the local inflammatory cascade in nasal tissue—reducing mast cell activity, eosinophil infiltration, and cytokine release triggered by allergen exposure—providing comprehensive relief of both early and late-phase allergic rhinitis symptoms.

Full symptom coverage

Addresses the complete spectrum of allergic rhinitis symptoms including nasal congestion, runny nose, sneezing, and itching—more comprehensive than antihistamines alone, which have limited effect on nasal congestion.

Minimal systemic absorption

Mometasone has very low bioavailability after intranasal administration, with most of the dose remaining active locally in the nasal mucosa—delivering effective anti-inflammatory control with negligible systemic corticosteroid exposure.
