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, seasonal and perennial allergic rhinitis, and nasal polyps in adults and children as prescribed, reducing nasal inflammation, congestion, itching, sneezing and improving overall nasal airflow and patient quality of life.

GNH USA supplies Nasonex as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide, ensuring quality assurance, regulatory compliance, and reliable logistics for global distribution.

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

Allergic rhinitis: reduces nasal congestion, itching, sneezing and rhinorrhea. Seasonal allergic rhinitis: provides symptom relief during pollen seasons. Perennial allergic rhinitis: controls year‑round nasal inflammation. Nasal polyps: helps shrink polyps and improve nasal airflow.

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

Common Side Effects: - Nasal irritation or burning: mild discomfort at the site of application. - Headache: transient headache following use. - Epistaxis: occasional nosebleeds. - Throat irritation: mild soreness or dryness.

Serious or Rare Side Effects: - Nasal septal perforation: rare tissue damage requiring medical attention. - Vision changes: rare blurred vision or cataract formation. - Adrenal suppression: systemic corticosteroid effect with prolonged high‑dose therapy.

Before prescribing Nasonex, clinicians should consider several safety and handling precautions.

- Assess infection: avoid use in patients with active nasal or sinus infections. - Monitor growth: pediatric patients should have growth monitored during long‑term therapy. - Evaluate glaucoma: caution in patients with glaucoma or cataracts. - Use with caution: avoid concomitant use of other intranasal corticosteroids. - Store at room temperature: keep the spray bottle in its original packaging, protect from moisture and heat.

Nasonex can interact with other medicines, primarily through additive corticosteroid effects.

Major Interactions (Avoid): - Systemic corticosteroids: increased risk of systemic steroid side effects. - Strong CYP3A4 inhibitors (e.g., ketoconazole): may raise local drug exposure.

Moderate Interactions (Monitor Closely): - Antifungal azoles: monitor for enhanced nasal effects. - Antiretrovirals (e.g., ritonavir): may increase local concentration. - Nasal decongestants: potential for increased nasal irritation.
