Nasonex (Mometasone Furoate)

Mometasone furoate, the active ingredient in Nasonex, is a glucocorticoid presented as a nasal spray for nasal use. It is indicated for the treatment of allergic rhinitis—including seasonal and perennial forms—as well as for reducing nasal polyps in adults and adolescents. The formulation delivers a targeted anti‑inflammatory effect directly to the nasal mucosa, minimizing systemic exposure.

GNH USA supplies Nasonex as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide, with a focus on reliable quality, regulatory compliance and timely global distribution.

Nasonex, an intranasal glucocorticoid, is used to manage inflammatory conditions of the nasal passages and related structures, providing both symptom relief and disease modification. Allergic rhinitis: reduces nasal congestion, sneezing, itching and rhinorrhea, improving overall nasal comfort. Seasonal allergic rhinitis: provides rapid symptom relief during pollen seasons, decreasing the need for oral antihistamines. Perennial allergic rhinitis: offers year‑round control of chronic nasal inflammation, helping maintain clear breathing throughout the year. Nasal polyps: helps shrink nasal polyps, reduces polyp size, and improves nasal airflow and sinus ventilation.

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 - Cough - Altered taste

Serious or Rare Side Effects: - Adrenal suppression - Fungal infection of nasal passages - Perforated nasal septum - Severe allergic reaction (anaphylaxis) - Vision changes

Before prescribing Nasonex, clinicians should consider several precautionary measures to ensure safe use. Pregnancy: consult a healthcare professional before use, as safety data are limited. Children: use only as directed; safety in children under two years has not been established. Active nasal infection: avoid use until infection is resolved to prevent worsening. Recent nasal surgery: discontinue or postpone use as advised by the surgeon. Concurrent systemic corticosteroids: monitor for additive systemic effects. Store at room temperature: keep in original packaging, protect from moisture and heat.

Nasonex can interact with other medicines, affecting its efficacy or safety.

Major Interactions (Avoid): - Strong CYP3A4 inhibitors (e.g., ketoconazole): may increase systemic exposure. - Systemic immunosuppressants: risk of additive immunosuppression. - Live vaccines: may reduce vaccine effectiveness.

Moderate Interactions (Monitor Closely): - Antifungal azoles (e.g., itraconazole): may modestly raise mometasone levels. - Ritonavir: may increase exposure, requiring observation. - Concurrent use of other nasal sprays: may increase local irritation.
