Nasonex (mometasone furoate) is a corticosteroid nasal spray used to treat inflammatory conditions of the nasal passages.

Allergic rhinitis: reduces nasal congestion, itching, and sneezing associated with allergic triggers. Seasonal allergic rhinitis: provides symptom relief during pollen or seasonal allergen exposure. Perennial allergic rhinitis: controls year‑round nasal inflammation caused by indoor allergens. Nasal polyps: decreases polyp size and improves nasal airflow and breathing.

Mometasone furoate nasal spray may cause local and, rarely, systemic adverse reactions.

Common Side Effects: - Nasal irritation or burning sensation - Epistaxis (nosebleed) - Headache - Sore throat - Cough - Altered taste or bitter aftertaste

Serious or Rare Side Effects: - Adrenal suppression with prolonged use - Increased intraocular pressure or glaucoma - Cataract formation - Fungal sinusitis or secondary infection - Severe allergic reaction (anaphylaxis) - Nasal septal perforation

When prescribing Nasonex, consider the following precautions.

Assess patient history: evaluate for recent nasal surgery or trauma. Avoid use in active infections: do not use if nasal or sinus infection is present without physician guidance. Monitor for systemic effects: watch for signs of cortisol suppression during long‑term therapy. Caution in glaucoma patients: may increase intraocular pressure. Pregnancy and lactation: use only if benefit outweighs risk after medical assessment. Store at room temperature: keep below 25 °C, protect from moisture and direct sunlight.

Mometasone furoate nasal spray can interact with other medicines; review patient medication lists.

Major Interactions (Avoid): - Strong CYP3A4 inhibitors: may increase systemic exposure of mometasone. - Systemic corticosteroids: additive glucocorticoid effects, risk of adrenal suppression.

Moderate Interactions (Monitor Closely): - Antifungal azoles (ketoconazole, itraconazole): may modestly raise mometasone levels. - Protease inhibitors such as ritonavir: potential increase in exposure. - Live vaccines: efficacy may be reduced if systemic absorption occurs.
