Nasonex (Mometasone Furoate)

Mometasone furoate, the active ingredient in Nasonex, is a corticosteroid presented as a nasal spray for nasal use. It treats allergic rhinitis and nasal polyposis in adults and children when prescribed by a healthcare professional.

GNH USA supplies Nasonex as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Nasonex, a nasal corticosteroid, is indicated for inflammatory conditions of the nasal passages.

Allergic rhinitis: relieves nasal congestion, itching, sneezing and rhinorrhea. Nasal polyposis: reduces polyp size and improves nasal airflow.

Nasonex may cause local and systemic adverse reactions, which are categorized by frequency.

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

Serious or Rare Side Effects: - Adrenal suppression - Vision changes such as cataracts - Severe allergic reaction (anaphylaxis) - Nasal septal perforation - Opportunistic fungal infection

Before using Nasonex, consider the following precautions to ensure safe and effective therapy.

Pregnancy: consult a healthcare provider before initiating therapy. Pediatric use: safety and efficacy not established in children under 2 years of age. Nasal surgery: avoid use immediately before and after surgical procedures on the nose. Concurrent systemic corticosteroids: monitor for additive glucocorticoid effects. Immunocompromised patients: assess risk of opportunistic infections. Store at room temperature: keep in the original container, protect from moisture and heat.

Nasonex can interact with other medicines; awareness of these interactions helps prevent adverse outcomes.

Major Interactions (Avoid): - Systemic corticosteroids: may increase overall glucocorticoid exposure. - Strong CYP3A4 inhibitors (e.g., ketoconazole, itraconazole): can raise mometasone levels.

Moderate Interactions (Monitor Closely): - Antifungal azoles (e.g., posaconazole): may modestly increase exposure. - Ritonavir: may elevate systemic concentrations. - Live vaccines: effectiveness may be reduced while using nasal corticosteroids.
