Nasonex is a topical nasal corticosteroid used to manage inflammatory conditions of the nasal passages.

Allergic rhinitis: reduces nasal congestion, itching, sneezing and rhinorrhea. Seasonal allergic rhinitis: alleviates symptoms triggered by seasonal allergens. Perennial allergic rhinitis: provides relief from year‑round allergic nasal inflammation. Nasal polyps: helps shrink polyps and improve nasal airflow.

Nasonex may cause local and systemic adverse reactions.

Common Side Effects: - Nasal irritation or burning sensation - Headache - Epistaxis (nosebleed) - Throat irritation or dryness - Cough - Altered taste or unpleasant taste

Serious or Rare Side Effects: - Nasal septal perforation - Severe allergic reaction (anaphylaxis) - Vision changes or cataract formation - Adrenal suppression with prolonged high‑dose use - Opportunistic fungal infection of the nasal passages

Before using Nasonex, consider the following safety points.

Pregnancy: consult a healthcare provider; limited safety data are available. Children: use only as prescribed and monitor for growth effects. Active nasal infection: avoid use until infection is resolved. Nasal or ear surgery: inform the surgeon of recent Nasonex use. Drug interactions: discuss all concomitant medications with the prescriber. Store at room temperature: keep in the original container, protect from moisture and heat.

Nasonex can interact with other medicines; monitor accordingly.

Major Interactions (Avoid): - Systemic corticosteroids: may increase risk of systemic glucocorticoid effects. - Strong CYP3A4 inhibitors (e.g., ketoconazole, ritonavir): can raise mometasone exposure.

Moderate Interactions (Monitor Closely): - Antifungal azoles and certain antibiotics: may modestly increase local drug levels. - Immunosuppressants: watch for additive immunosuppression. - Live vaccines: consider timing to avoid reduced vaccine efficacy. - Herbal supplements (e.g., St. John’s wort): may affect metabolism.
