About mometasone nasal spray

Type of medicineCorticosteroids
Used forNasal allergy and polyps
Also calledNasonex®
Available asNasal spray

Exposure to irritants such as pollen, pet fur or pollution can cause allergic rhinitis. This is where the inside of the nose becomes swollen and itchy which in turn causes sneezing and a continually runny nose. Mometasone reduces inflammation and swelling in the nose which in turn relieves congestion, itching, sneezing, irritation and discomfort.

Mometasone nasal spray may also be used to treat the symptoms caused by nasal polyps. Polyps are small lumps found in the nose. They can cause symptoms such as a runny nose, reduced sense of smell and sometimes if severe, difficulty breathing through the nose.

Before using mometasone nasal spray

Before using mometasone nasal spray make sure your doctor or pharmacist knows:

  • If you are pregnant, trying for a baby or breast-feeding.
  • If you have recently had nasal surgery.
  • If you have tuberculosis (TB) in the lungs.
  • If you are taking any steroid type medicines; including inhalers and tablets.
  • If you have recently suffered from a nasal infection.
  • Mometasone nasal spray is not suitable for use in children under 6 years of age.

How to use mometasone nasal spray

  1. Blow your nose gently.
  2. Shake the container and remove cap. If it is the first time you have used the spray, pump the spray into the air away from your eyes for 6 or 7 times, until a fine mist is produced. You may also need to do this when the spray has not been used for a week or so.
  3. Put your forefinger and middle finger either side of the nozzle and your thumb underneath the bottle.
  4. Tilt your head forward slightly and insert the nozzle of the spray into the nostril, taking care to keep the canister upright as shown in the instruction leaflet. Whilst you are breathing in through your nose, push down gently on the canister to administer one dose.
  5. If a second dose is required, administer another dose.
  6. Repeat in the other nostril if you have been instructed to use mometasone in both nostrils.
  7. Wipe the nozzle with a clean tissue and replace the cap immediately after use.

Getting the most from your treatment

  • After a few weeks your dose may need adjusting, although you should discuss this with your doctor before making any change.
  • If you are using mometasone nasal spray to relieve the symptoms of hayfever, your doctor may recommend that you start using the nasal spray four to six weeks before the symptoms usually start.
  • If you need to use this nasal spray for a long time your doctor may want to monitor your progress. This is particularly the case in children who use this spray.
  • Avoid getting mometasone in your eyes. If you accidentally get any mometasone in your eyes, rinse it out with plenty of water.
