Nasonex (Mometasone Furoate)

Mometasone furoate, the active ingredient in Nasonex, is a corticosteroid presented as a nasal spray for nasal use. The medication is formulated for once‑daily intranasal administration, providing localized anti‑inflammatory effects with minimal systemic absorption. It is indicated for the treatment of allergic rhinitis and nasal polyps in adults and children, as directed by a healthcare professional.

GNH USA supplies Nasonex as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide, ensuring consistent quality and regulatory compliance across global markets.

Nasonex (mometasone furoate) is a nasal corticosteroid that reduces inflammation in the nasal passages. - Allergic rhinitis: alleviates nasal congestion, itching, and sneezing by decreasing mucosal inflammation. - Seasonal allergic rhinitis: provides symptom relief during pollen seasons through local anti‑inflammatory action. - Nasal polyps: shrinks polyp size and improves nasal airflow, helping to restore normal breathing.

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 or cough

Serious or Rare Side Effects: - Adrenal suppression leading to systemic corticosteroid effects - Glaucoma or cataract formation with prolonged use - Severe nasal septum perforation or fungal infection of the nasal mucosa

Before prescribing Nasonex, clinicians should evaluate the following precautions to ensure safe use. - Assess adrenal function: consider risk of systemic corticosteroid exposure, especially with long‑term use. - Monitor intraocular pressure: patients with glaucoma or a family history should have regular eye examinations. - Avoid use in untreated fungal infection: treat the infection before initiating therapy. - Use with caution in children: monitor growth velocity during prolonged treatment. - Store at room temperature: keep in the original container, protect from moisture and heat.

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

Major Interactions (Avoid): - Strong CYP3A4 inhibitors: may increase systemic exposure to mometasone furoate. - Systemic corticosteroids: additive immunosuppressive effects can raise infection risk. - Live vaccines: reduced efficacy due to local immunosuppression.

Moderate Interactions (Monitor Closely): - Antifungal azoles (e.g., ketoconazole): may raise mometasone levels. - Ritonavir or other protease inhibitors: potential increase in corticosteroid exposure. - Diuretics: may affect electrolyte balance when systemic absorption occurs.
