### Active Ingredient

Each spray delivers 50 micrograms of mometasone furoate monohydrate, a corticosteroid known for its local anti-inflammatory and anti-allergic properties. This formulation ensures targeted relief with minimal systemic absorption, reducing the likelihood of widespread side effects.

### Inactive Ingredients

- Dispersible cellulose

- Glycerol

- Citric acid

- Sodium citrate

- Polysorbate 80

- Purified water

- Benzalkonium chloride (as a preservative)

These components contribute to the stability and efficacy of the product.

### Dosage and Administration

- **Children (3 to 11 years):** One spray in each nostril once daily.

- **Nasal Polyps and Acute Rhinosinusitis:** Dosage adjustments as needed.

Proper administration includes shaking the bottle well before use, priming the spray if unused for 14 days or more, and regular cleaning of the nozzle.

### Onset and Duration

Some patients may experience relief within 12 hours, with full benefits typically observed after 48 hours of regular use. The once-daily dosing provides 24-hour symptom control, making it convenient for continuous management of allergy symptoms.

### Precautions

Nasonex should be used with caution in individuals with untreated nasal infections, recent nasal surgery, or trauma. Long-term use may necessitate regular eye examinations due to potential risks of glaucoma or cataracts. It is important to consult a healthcare provider if pregnant, planning to become pregnant, or breastfeeding.

Common side effects include headache, sneezing, nosebleeds, and nasal irritation. More serious effects, though rare, may include severe allergic reactions, nasal ulceration, and eye problems. Monitoring is advised, especially in children, to manage any potential impact on growth.

### Storage

Store the spray at room temperature, away from light and moisture. It should not be frozen and must be discarded after the labeled number of uses or within two months of opening. Keeping it out of reach of children and pets is essential.

### Packaging

The product comes in a white, high-density polyethylene bottle with a metered-dose spray pump. Various pack sizes are available, though not all may be marketed in every region. The formulation is alcohol-free, scent-free, and does not contain fluorocarbon propellants, making it suitable for a wide range of users.
