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.

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: reduces nasal congestion, itching, sneezing and rhinorrhea. Nasal polyposis: decreases polyp size and improves nasal airflow. Seasonal allergic rhinitis: provides symptom relief during pollen exposure.

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 smell

Serious or Rare Side Effects: - Nasal septal perforation - Severe allergic reaction (anaphylaxis) - Vision changes or cataract formation - Adrenal suppression with systemic effects - Opportunistic fungal infection in the nasal cavity - Persistent nasal ulceration

Before using Nasonex, consider the following safety measures.

Avoid use in untreated nasal infections: treat infection first. Monitor for signs of adrenal suppression: especially with prolonged high‑dose use. Caution in patients with glaucoma or cataracts: may increase intra‑ocular pressure. Do not abruptly discontinue after long‑term therapy: taper as advised. Store at room temperature: keep in the original pack, protect from moisture and heat.

Nasonex can interact with other medicines; review the following categories.

Major Interactions (Avoid): - Strong CYP3A4 inhibitors (e.g., ketoconazole) may increase systemic exposure. - Concurrent systemic corticosteroids: risk of additive glucocorticoid effects.

Moderate Interactions (Monitor Closely): - Azole antifungals (e.g., itraconazole) may modestly raise levels. - Protease inhibitors (e.g., ritonavir) may affect metabolism. - Drugs that affect wound healing: monitor nasal mucosa integrity.
