Nasonex® (mometasone) nasal spray treats the cold-like symptoms of allergic rhinitis – including sneezing, a runny or blocked nose – by reducing inflammation at the source. Unlike a common cold, these allergy symptoms can persist for weeks or months.

It belongs to a class of medications known as corticosteroids, preventing and treating symptoms of Hayfever. Its daily use eases allergy-related symptoms, making breathing easier. This medicine is approved for use in adults and children who are at least 2 years old. 

Hay fever/perennial allergies

Hay fever is not just a condition of the summer; it can persist all year, as it can be triggered by pollen from different types of plants, trees, grasses, and weeds. It is called perennial rhinitis, and during winter months, it can be triggered by dust mites, feathers, certain foods, animal hair (or dander), and mold spores. The symptoms of perennial allergic rhinitis and hay fever are:

• Coughing
• Sneezing 
• Pressure around the forehead and cheekbones
• Runny or blocked nose
• Loss of smell
• Earache
• Fatigue 
• Headache
• Itchy nose

How Effective is Nasonex?

Nasonex is a highly effective nasal spray for relieving allergy symptoms like congestion, sneezing, and a runny nose. It’s recommended by the NHS and works directly in the nose to reduce inflammation, providing longer-lasting relief than antihistamines alone.

How long does it take to work? NASONEX® Nasal Spray starts working within 12 hours, but you might not get the full benefit in the first 48 hours.

Many users in the UK report significant improvement within a few days of regular use. For best results, use it daily as prescribed. If your symptoms don’t improve after 1-2 weeks, speak to your GP—you may need a different treatment.

However, the full effect may take a few days of consistent use, particularly if your symptoms are severe or long-standing. If you are using it for hay fever, your doctor may recommend you start using Nasonex a week or two before pollen season begins to prevent symptoms from even starting. 

Nasonex hayfever spray contains mometasone furoate, which directly targets inflammation in the nasal passages and stops the production of those chemicals that cause allergic reactions.

When you spray it into your nose, it reduces swelling, irritation, and mucus production, easing symptoms such as itchiness, sneezing, and congestion caused by hay fever or perennial rhinitis. Unlike decongestant sprays, which lead to rebound congestion with overuse, Nasonex is safe for long-term use under medical supervision. 

You must use Nasonex for allergies according to your doctor’s recommendations, such as:

Priming the bottle

Before using Nasonex spray for the first time, prime your bottle by pumping the spray 10 times until a fine mist is produced. If you have not used the spray for 14 days or more, re-prime your device by pumping the spray 2 times until a fine mist is produced. The priming process includes:

• Gently shake your bottle
• Put your forefinger and middle finger on either side of the nozzle with your thumb underneath the bottle. Do not pierce the nasal applicator.
• Point the nozzle away from you, and after this, press down with your fingers to pump the spray until a fine mist is produced. 

Administration

• Shake your bottle gently and remove the dust cap.
• Gently blow your nose.
• Close your one nostril with your finger and put the nozzle into the other nostril. 
• Tilt your head forward slightly and keep the bottle upright.
• Gently breathe through your nose whilst squirting the spray into your nose once with your fingers. 
• Breath out through your mouth. 
• Repeat the same process if you need to take another spray in the same nostril.
• Remove the nozzle from your nostril and breathe out through your mouth.
• Wipe the nozzle and replace the dust cap. 

Do not share your medicine with others, and do not take more or less than the recommended dose. If you are still unsure how to use Nasonex spray, read the patient leaflet. 

How long do you need to take Nasonex for?

The duration of treatment depends on your doctor’s recommendations and the condition being treated. Usually, you can take Nasonex for up to 12 weeks. You must consult your doctor if you do not feel better after using it for 14 days.

Each actuation delivers 50 micrograms of mometasone furoate (as the monohydrate).

For Perennial Rhinitis or Seasonal allergies

Adults (12+ years): Start with 2 sprays in each nostril once daily. If symptoms improve, reduce to 1 spray per nostril daily. If symptoms persist, your doctor may increase the dose to 4 sprays in each nostril once daily.

For nasal Polyps

• Two actuations/spray (50 micrograms/actuation) in each nostril once daily. 

If symptoms do not improve after 5 to 6 weeks, the dose is increased to 2 actuations (50 micrograms/actuation) in each nostril twice daily.

Nasonex nasal spray is generally considered safe during breastfeeding as it is applied locally in the nose and has very low systemic absorption. It passes into breast milk in very low amounts and is unlikely to pose a risk to a breastfeeding infant when used as directed. However, you must consult your doctor before taking this medicine while breastfeeding. For more please read Patient Leaflet

If Nasonex does not suit you, you can try other options such as Telfast and Neoclarityn. Both are non-drowsy antihistamine tablets and are widely used in the UK. They block the effects of histamine and treat sneezing, itchy eyes, runny nose, and skin rashes.

Telfast: It is a stronger medicine and is used when other antihistamines are not effective. It is taken once daily and is effective for those with moderate to severe allergies. 

Neoclarityn: It is a newer antihistamine with a good safety profile and minimal side effects. It is also taken once daily. 

Besides these, other alternatives for treating hay fever, nasal inflammation, and allergic rhinitis are:

• Beconase Nasal Spray
• Rhinolast Nasal Spray
• Dymista Nasal Spray
• Avamys Nasal Spray

If nasal sprays don’t work for you or aren’t suitable, Fexofenadine tablets offer an effective alternative for hay fever relief.

Consult your doctor to determine the safe and appropriate option for you based on your medical profile and current needs.
