What is mometasona spray nasal?
Mometasona nasal spray is a type of corticosteroid, also known as a nasal steroid, that is administered as a fine mist into the nose. Its active ingredient, mometasone furoate, reduces inflammation in the nasal passages, which is often the root cause of allergic symptoms. Unlike oral antihistamines that focus on blocking histamines, this spray targets the underlying inflammatory response directly in the nasal lining, making it highly effective for chronic issues. It is available in various formulations, with both over-the-counter (OTC) and prescription-strength versions available for different indications and age groups.
Key uses of mometasona nasal spray
Mometasona spray is used to address several conditions that cause nasal and sinus discomfort:
- Allergic Rhinitis: This includes both seasonal allergies (hay fever) and perennial allergies (year-round) triggered by things like pollen, dust mites, mold, and pet dander. The spray prevents and relieves sneezing, runny nose, stuffy nose, and nasal itching.
- Nasal Polyps: In adults, mometasone nasal spray is prescribed to treat nasal polyps, which are noncancerous growths on the lining of the nose or sinuses.
- Prevention of Seasonal Allergies: The prescription version can be used to prevent seasonal allergic symptoms in individuals 12 years and older by starting use 2 to 4 weeks before the pollen season begins.
It is important to note that mometasone nasal spray is not used for treating symptoms caused by the common cold, as colds are caused by viruses, not inflammatory allergic reactions.
How mometasona spray nasal works
The mechanism of action for mometasone is its anti-inflammatory properties. It works at a cellular level to inhibit the release of inflammatory mediators—natural substances in the body that cause the symptoms of an allergic reaction, such as swelling, redness, and itching. By delivering the corticosteroid directly to the nasal passages, the medication minimizes systemic absorption, reducing the risk of widespread steroid-related side effects.
For optimal effect, mometasone should be used regularly rather than as needed, as its full benefit is typically achieved after 1 to 2 weeks of consistent use. This is because it takes time for the medication to build up in the nasal tissues and effectively control the inflammatory process.
How to use mometasona spray nasal
To ensure the best results and minimize side effects, it is crucial to use the spray correctly. Always follow the instructions provided by your doctor or on the package label.
Here is a general guide on how to use it:
- Preparation: Shake the bottle gently before each use. If it's a new bottle or has not been used for over a week, you must prime the pump by spraying into the air until a fine mist appears.
- Clear Nasal Passages: Gently blow your nose to clear the nostrils.
- Positioning: Tilt your head slightly forward and close one nostril by pressing a finger against the side of your nose.
- Administer Spray: Insert the nozzle into the open nostril, pointing it slightly away from the nasal septum (the middle wall of the nose).
- Inhale and Spray: As you begin to breathe in gently through your nose, press down firmly on the pump to release one spray.
- Repeat (if needed): If a second application is required for that nostril, repeat the process. Then, repeat the entire procedure for the other nostril.
- Finalize: Wipe the nozzle with a clean tissue and replace the cap.
Potential side effects and precautions
Like all medications, mometasone nasal spray can cause side effects. These can range from common and mild to rare but serious.
Common side effects
- Headache
- Nosebleeds (epistaxis)
- Sore throat or throat irritation
- Nasal burning or irritation
- Flu-like symptoms
- Unpleasant taste or smell
Serious side effects and precautions
If you experience any of the following, contact your doctor immediately:
- Nasal problems: Severe nosebleeds, sores that won't heal, or a whistling sound when breathing can indicate nasal septum perforation.
- Eye problems: Long-term use can increase the risk of glaucoma or cataracts. Monitor for blurred vision, eye pain, or vision changes.
- Infections: As a corticosteroid, it can increase the risk of fungal or other infections. White patches in the nose or throat could signal candidiasis.
- Adrenal function: High doses over a long period can lead to hypercorticism or adrenal suppression.
- Growth in children: Prolonged use in children and adolescents may cause slowed growth.
Contraindications: Avoid use if you have recently had nasal surgery, nasal sores, or a nasal injury, as mometasone can impair wound healing. Use with caution in patients with active tuberculosis, systemic infections, or ocular herpes simplex.
Mometasone vs. Fluticasone: A comparison
Both mometasone and fluticasone are popular corticosteroid nasal sprays for treating allergies. Here is a comparison to highlight their key differences based on information from GoodRx.
| Feature | Mometasone (Nasonex) | Fluticasone (Flonase) |
|---|---|---|
| Active Ingredient | Mometasone furoate | Fluticasone propionate (Allergy Relief), Fluticasone furoate (Sensimist) |
| Availability | Prescription and OTC versions available | Prescription and OTC versions available |
| Common Uses | Allergic rhinitis, nasal polyps | Allergic rhinitis, itchy/watery eyes |
| Pediatric Use (OTC) | As young as 2 years old | As young as 2 years old (Sensimist) |
| Duration of Use | Can be used long-term for polyps under a doctor's care | OTC versions for up to 6 months (adults), prescription can be longer |
| Side Effects (Headache) | Higher reported rate (26% in trials) | Lower reported rate (7-16% in trials) |
| Overall Efficacy | Generally considered equally effective for allergic rhinitis. | Generally considered equally effective for allergic rhinitis. |
| Patient Preference | Some studies show preference for mometasone due to less odor and taste. | Some studies show a preference for other options. |
Conclusion
Mometasona spray nasal is a powerful and effective corticosteroid medication for managing allergic rhinitis and nasal polyps. By directly targeting inflammation in the nose, it provides relief from sneezing, congestion, and itching. While it is generally well-tolerated, it is important to understand its proper usage, potential side effects, and precautions. For long-term use, especially in children or patients with underlying conditions like eye problems or infections, a doctor's supervision is essential. If you suffer from chronic nasal or sinus issues, consulting a healthcare provider can help determine if mometasone is the right solution for you.
