Nasonex (Mometasone Furoate)

Mometasone furoate, the active ingredient in Nasonex, is a corticosteroid presented as a nasal spray for nasal administration. It reduces inflammation in the nasal passages and is used to treat allergic rhinitis and nasal polyps in adults and children.

GNH USA supplies Nasonex as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide. The company adheres to stringent quality standards and provides regulatory documentation for cross‑border distribution. Our logistics network ensures timely delivery and temperature‑controlled handling where required.

Nasonex, a nasal corticosteroid, acts on inflammatory pathways of the nasal mucosa to relieve symptoms of several upper‑respiratory conditions.

Allergic rhinitis: reduces nasal congestion, sneezing, itching and rhinorrhea. Seasonal allergic rhinitis: provides relief during pollen exposure by decreasing mucosal inflammation. Perennial allergic rhinitis: alleviates chronic nasal symptoms through anti‑inflammatory action. Nasal polyps: shrinks polyp size and improves nasal airflow, reducing obstruction.

Nasonex may cause local and systemic adverse reactions, most of which are mild and reversible.

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

Serious or Rare Side Effects: - Nasal septal perforation - Adrenal suppression - Glaucoma or cataract development - Severe allergic reaction (anaphylaxis) - Fungal infection of the nasal passages

Before prescribing Nasonex, clinicians should evaluate patient history and follow specific safety measures. - Assess for active nasal or sinus infections: postpone use until infection resolved. - Review ocular history: monitor intra‑ocular pressure in patients with glaucoma or cataract risk. - Evaluate for hypersensitivity: discontinue if signs of allergic reaction appear. - Use the lowest effective dose: limit duration to the shortest period required for symptom control. - Caution in children: follow pediatric dosing guidelines and monitor growth if long‑term use. - Store at room temperature: keep in the original package, protect from moisture and direct sunlight.

Mometasone furoate can interact with other medicines that affect corticosteroid metabolism or immune function.

Major Interactions (Avoid): - Strong CYP3A4 inhibitors (e.g., ketoconazole, itraconazole): may increase systemic exposure and risk of adrenal suppression. - Live vaccines: systemic immunosuppression may reduce vaccine efficacy and increase infection risk.

Moderate Interactions (Monitor Closely): - Systemic corticosteroids: additive glucocorticoid effects may enhance systemic side effects. - Antifungal azoles (e.g., fluconazole): moderate increase in mometasone levels, monitor for adverse effects. - Ritonavir or other protease inhibitors: may raise mometasone concentrations, observe for signs of excess glucocorticoid activity.
