Nasonex (Mometasone Furoate)

Mometasone furoate, the active ingredient in Nasonex, is a corticosteroid presented as a 50 µg per spray nasal spray for nasal use. It treats allergic rhinitis and nasal polyps in adults and children as indicated.

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

Nasonex is a nasal corticosteroid that reduces inflammation of the nasal mucosa in allergic and polyp conditions. - Allergic rhinitis (seasonal): relieves nasal congestion, sneezing, itching and rhinorrhea. - Allergic rhinitis (perennial): improves chronic nasal symptoms and quality of life. - Nasal polyps: decreases polyp size and restores nasal airflow.

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

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

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

Before using Nasonex, consider the following safety measures. - Pregnancy: consult a healthcare professional as safety data are limited. - Breastfeeding: weigh potential benefits against unknown risks. - Pediatric use: follow age‑specific dosing recommendations. - Concurrent nasal surgery: avoid use immediately before or after procedures. - Long‑term high‑dose therapy: monitor for signs of adrenal suppression. - Store at room temperature: keep in the original container, protect from moisture and heat.

Nasonex can interact with other medications that affect corticosteroid metabolism or immune response.

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

Moderate Interactions (Monitor Closely): - Moderate CYP3A4 inhibitors (e.g., fluconazole): may modestly increase exposure. - Ritonavir: potential increase in systemic levels. - Live attenuated vaccines: possible reduced vaccine efficacy.
