Hayfever is an allergy to pollen and it affects around 1 in 4 people, it can make the summer rather unpleasant if it keeps you indoors. Hayfever usually occurs between March and September in the UK and is at its worst in June and July when the pollen count is the highest. Symptoms of hayfever include itchy eyes, a blocked or runny nose, sneezing or coughing and an itchy sore throat to name a few – asthma sufferers may also find they cough and wheeze, for some it almost feels like having a permanent cold. Treatments are available over the counter and on prescription such as antihistamines or other products containing antihistamines or steroids like a nasal spray. These treatments, when taken regularly can help to control the symptoms of hayfever meaning sufferers can enjoy being outdoors in summer like the rest of the population. 

What is Nasonex Nasal Spray? 

Nasonex Nasal Spray is a spray that, as its name suggests, is sprayed into the nostrils. 

It contains the active ingredient mometasone furoate, which belongs to the corticosteroids group of medicines. 

Corticosteroids are used to treat all kinds of inflammation, swelling and irritation within the body – in this case, it treats the inflammation and irritation in the nose. 

When is Nasonex Nasal Spray used? 

Nasonex Nasal Spray is used to treat the following: 

  • Hayfever; 
  • Perennial Rhinitis (an allergy that occurs all year round); 
  • Nasal polyps (a type of growth in the nose). 

It can be used by adults and children over the age of three. 

It works by relieving sneezing, itching and a blocked-up or runny nose and reducing the inflammation in the nose caused by any of the conditions listed above. 

How do you use Nasonex Nasal Spray? 

Always follow the instructions of your doctor or pharmacist when it comes to taking medicines and check with them if you are unsure about anything. 

If you are using Nasonex for the first time, or you are using a bottle that hasn’t been used for more than 14 days you will need to ‘prime’ the bottle before you use it, to do this: 

  • Shake the bottle gently; 
  • Place your thumb underneath the bottle and your forefinger and middle finger either side of the bottle; 
  • Point the nozzle away from you; 
  • If this is a new bottle spray 10 times until you produce a fine mist; 
  • If this is a bottle you had already opened but haven’t used for more than 14 days spray twice until you produce a fine mist. 

To take Nasonex: 

  • Gently blow your nose before you start; 
  • Shake the spray; 
  • Remove the cap (always keep the cap on unless you are using it, to prevent dust from gathering); 
  • Hold the spray in an upright position, resting on your thumb with your forefinger and middle finger on either side of the nozzle; 
  • Tip your head forwards slightly and close one nostril with your finger; 
  • Place the nozzle of the spray in the other nostril – you don’t need to push it in too hard or too far; 
  • Aim the nozzle away from the centre of your nose, towards the inside of corner of your eye on the same side; 
  • Press the applicator firmly down between your fingers and your thumb and breathe in gently through your nose; 
  • Do not sniff hard as the medicine will end up in your throat rather than in your nose; 
  • As you breathe out gently through the mouth, remove the nozzle from your nostril; 
  • Place the Nasonex nasal spray in the other hand and spray into the other nostril following the same process as for the first nostril; 
  • Wipe the nozzle to clean it and replace the cap before storing in a safe place; 
  • Do not blow your nose immediately after using the Nasonex spray as the medicine will come out. 

You will need to clean your Nasonex Nasal spray regularly to keep it working properly: 

  • Remove the dust cap and gently remove the nozzle; 
  • Wash both of the above in warm water and rinse under a running tap; 
  • Do not push anything into the applicator to try and clean it, you are more likely to cause damage; 
  • Allow the dust cap and nozzle to dry in a warm place; 
  • Place them both back onto the bottle; 
  • After you have cleaned your nasal spray you will need to prime it with 2 sprays the next time you use it. 

What dosages are there? 

When it comes to how much medicine to take and for how long, always listen to the instructions of your doctor or pharmacist. 

Nasonex should be taken regularly to have the best effect, try to remember to take it at the same time every day. 

To treat hayfever in adults and children over 12: 

  • Two sprays into each nostril once a day; 
  • You may be able to decrease the dose once your symptoms are under control but you should only do this on the recommendation of your doctor; 
  • If you find the spray is not helping you may be able to increase the dose to a maximum of four sprays in each nostril once a day but only do this on the recommendation of your doctor. 

To treat hayfever in children aged 3-11: 

  • One spray into each nostril once a day. 

Using Nasonex regularly will offer the most benefit and you may be advised to start using it before the start of pollen season as it will help prevent hay fever from occurring. 

To treat nasal polyps in adults over the age of 18: 

  • Two sprays into each nostril once a day; 
  • The dose may be increased after 5 to 6 weeks if the symptoms are not controlled, to two sprays in each nostril twice daily and can be decreased again once symptoms are under control; 
  • If your condition does not improve after 5 to 6 weeks of using Nasonex twice a day then speak to your doctor.
