Mometasone nasal spray eases the symptoms of a stuffy, runny or itchy nose (rhinitis).
It may take a few days of treatment before you feel the full effect.
If you are using it for hay fever, start using it 2-3 weeks before the hay fever season begins and use it regularly.
Any side-effects are usually mild.
About mometasone nasal spray
|Type of medicine||Corticosteroid|
|Used for||Nasal symptoms caused by allergies; nasal polyps|
|Available as||Nasal spray|
Mometasone nasal spray is used to ease, rhinitis. This is a condition where the inside of your nose becomes inflamed and irritated. Common symptoms include sneezing, a blocked or congested nose, a runny nose (watery discharge), and an itchy nose. It is commonly caused by allergies, such as hay fever. Mometasone belongs to a group of medicines called corticosteroids. It reduces inflammation and swelling and so relieves the congestion, itching, sneezing, irritation and discomfort of rhinitis.
Mometasone nasal spray is also prescribed as a treatment for nasal polyps. Polyps are small growths inside the nose that can cause symptoms similar to allergic rhinitis.
Before using mometasone nasal spray
Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start using mometasone, it is important that your doctor knows:
- If you have an infection in your nose.
- If you have recently had any surgery on your nose.
- If you have tuberculosis (TB).
- If you are pregnant.
- If you are taking or using other medicines. This includes any medicines you are taking which are available to buy without a prescription, as well as herbal and complementary medicines.
- If you have ever had an allergic reaction to a medicine.
How to use mometasone nasal spray
- Read the manufacturer's instructions to make sure you know how to work the spray.
- Shake the bottle gently and remove the cap. (Before you use the spray for the first time, activate the spray a few times until you can see a fine mist in the air.)
- Blow your nose gently to clear it.
- Close one nostril by placing a finger against one side of your nose. Then, using your other hand, put one finger on each side of the nozzle of the bottle and insert the nozzle into your open nostril. Try to keep the bottle upright as you do this.
- Breathe in through your nose as you activate the spray. Then remove the nozzle from your nostril and breathe out through your mouth. Repeat if you are using two sprays for each dose.
- Repeat the step above in your other nostril.
- Wipe the nozzle with a clean tissue and replace the cap. (If the nozzle becomes blocked, you can remove it from the bottle and rinse it under warm water.)
Getting the most from your treatment
- Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack. This will give you a step-by-step guide of how to use the spray, and will also provide you with a full list of the side-effects which you may experience from using it.
- When you first start using mometasone, it is usual to use two sprays into both nostrils each morning for adults and for children over 12 years of age, and just one spray into each nostril each morning for children aged 3-11 years. Once your symptoms are controlled, you may be advised to reduce the dose. Your doctor will advise you how long to use the spray for.
- If you are using the spray for hay fever, your doctor may recommend that you start using it 2-3 weeks before the hay fever season starts. This is because it takes a few days of treatment before you feel the full effect, so starting before the pollen count rises will help to prevent symptoms from developing.
- Try to remember to use mometasone spray regularly, even if your symptoms are controlled. If you forget a dose at your usual time, take it as soon as you remember unless your next dose is due. If your next dose is due then have the dose which is due and leave out the forgotten one. Do not 'double up' to make up for a missed dose.
- Do not use the spray more often, or for a longer period of time, than your doctor has recommended. This can increase the risk of side-effects.
- If you need to use the spray over several months, your doctor may want to monitor your progress. This is particularly important for children who use the spray.
