Product Description

Nasonex spray containing the corticosteroid Mometasone Furoate is intended for use in the nose. Regular daily use of a steroid nasal spray like Nasonex can help with reducing inflammation in the sinuses and nasal passages which can be triggered by airborne allergens like pollen.

Contrary to popular belief hay fever is not just a condition of the summer. There are hay fever seasons for different types of plants, and in those susceptible allergies can persist all year. This is known as perennial rhinitis and during winter months allergies can be triggered by mould spores and dust mites.

Typical symptoms of hay fever and perennial allergic rhinitis include:

  • sneezing
  • coughing
  • runny or blocked nose
  • pressure around the forehead and cheekbones
  • loss of smell
  • fatigue
  • earache
  • headache



The usual dose of Nasonex is two sprays into each nostril once daily. Once your symptoms are under control the dose should be reduced to one spray in each nostril daily. Whilst suitable for regular daily use it is advisable to discontinue this medicine periodically, especially if your rhinitis is seasonal.

Symptoms should start improving within a few days but the real benefits obtained from Nasonex only occur if the medicine is used every day to prevent symptoms rather than treat them.

Preparing your nasal spray for use:

Your Nasonex Nasal Spray has a dust cap which protects the nozzle and keeps it clean. Remember to take this off before using the spray and to replace it after use. If you are using the spray for the first time you need to ‘prime’ the bottle by pumping the spray 10 times until a fine mist is produced.

  • Gently shake the bottle.
  • Put your forefinger and middle finger on either side of the nozzle and your thumb underneath the bottle. Do Not pierce the nasal applicator.
  • Point the nozzle away from you and then press down with your fingers to pump the spray 10 times until a fine mist is produced.
  • If you have not used the spray for 14 days or more, you need to “re-prime” the bottle by pumping the spray 2 times until a fine mist is produced.

Using your nasal spray:

  • Shake the bottle gently and remove the dust cap.
  • Gently blow your nose.
  • Close one nostril and put the nozzle into the other nostril as shown. Tilt your head forward slightly, keeping the bottle upright.
  • Start to breathe in gently or slowly through your nose and whilst you are breathing in squirt a spray of fine mist into your nose by pressing down ONCE with your fingers.
  • Breathe out through your mouth. Repeat step 4 to inhale a second spray in the same nostril if applicable.
  • Remove the nozzle from this nostril and breathe out through the mouth.
  • Repeat steps 3 to 6 for the other nostril. After using the spray, wipe the nozzle carefully with a clean handkerchief or tissue and replace the dust cap.

Use with other medicines
