Mometasone Nasal Spray (Clarinaze, Nasonex)
Effective relief from allergic rhinitis and nasal polyps with mometasone nasal spray for adults and children.
Mometasone nasal spray is a corticosteroid medication designed to treat and prevent symptoms of allergic rhinitis, commonly known as hay fever, and nasal polyps in adults.
About mometasone nasal spray
Mometasone nasal spray helps ease rhinitis, a condition causing inflammation and irritation inside the nose. Symptoms often include sneezing, a blocked or congested nose, runny nose, and itching, typically triggered by allergies like hay fever. As a corticosteroid, mometasone reduces swelling and inflammation, providing relief from congestion, itching, sneezing, and discomfort.
It is suitable for adults and children from age 6 years for allergic rhinitis prevention and treatment. For nasal polyps, it is primarily used in adults. Unlike antihistamines, it targets inflammation directly and should not be used for common cold symptoms.
Brands include Clarinaze and Nasonex, available over-the-counter or by prescription depending on the region and indication.
Before using mometasone nasal spray
Consult a doctor before starting, especially if you have untreated nasal infections, recent nasal surgery or injury, glaucoma, cataracts, or tuberculosis history. Inform your doctor of any allergies to mometasone or other corticosteroids, or if pregnant, breastfeeding, or using other nasal products.
It may interact with HIV protease inhibitors like Ritonavir, potentially increasing corticosteroid effects. Avoid if hypersensitive to mometasone furoate or excipients.
How to use mometasone nasal spray
Follow your doctor’s or package instructions precisely. Shake the bottle well before each use. Clear nostrils by gently blowing your nose.
Steps for use:
- Wash hands thoroughly.
- Remove cap and check nozzle is clear.
- Prime if new: point away from face and spray until fine mist appears (up to 10 sprays).
- Close one nostril with finger, insert nozzle into open nostril, keep bottle upright.
- Breathe in gently through nose, press nozzle firmly to spray while inhaling.
- Remove nozzle, breathe out through mouth.
- Repeat for second spray if required, then other nostril.
- Wipe nozzle with clean tissue, replace cap.
Do not spray into eyes or mouth; for nasal use only. An adult should supervise children under 12.
Dosage
Dosage varies by age, condition, and severity. Start with higher dose for control, then reduce as advised.
| Condition | Adults & 12+ years | Children 2-11 years | Children <2 years |
|---|---|---|---|
| Seasonal/Perennial Allergic Rhinitis Treatment | 2 sprays each nostril once daily (100 mcg/day) | 1 spray each nostril once daily (50 mcg/day) | Doctor-determined |
| Prevention of Seasonal Allergic Rhinitis | 2 sprays each nostril once daily (200 mcg/day), start 2-4 weeks before pollen season | Doctor-determined | Not recommended |
| Nasal Polyps | 2 sprays each nostril twice daily (400 mcg/day) or once daily (200 mcg/day) | Doctor-determined | Not recommended |
Each spray delivers 50 mcg mometasone furoate. Maximum duration: up to 3 months; doctor may advise longer for polyps. Full effects may take 12 hours to 2 weeks.
Getting the most from your treatment
Use regularly for best results, even if symptoms improve. Continue as prescribed; do not stop abruptly without advice. For seasonal allergies, begin 2-4 weeks pre-pollen season. Combine with allergen avoidance like staying indoors during high pollen, using air filters.
If no improvement after 14 days, consult doctor. Track symptoms and usage.
Side effects
Common side effects are mild and nasal-localized, often improving with time.
| Common Side Effects | What to Do |
|---|---|
| Slight nosebleeds, nasal irritation/burning, throat irritation | Speak to doctor if persistent |
