What is Nasonex?

Nasonex is a steroid nasal spray used to treat the symptoms of hay fever and allergies.

Symptoms of hay fever and allergies include congestion, a runny and itchy nose, sneezing, and watery or red eyes. 

Nasonex nasal spray is prescription-only medicine, which means you need to be prescribed it by a doctor or pharmacist to buy it. 

What is Nasonex used for?

Nasonex nasal spray is used to prevent and treat symptoms of hay fever and allergy, such as:

  • A runny nose
  • A blocked nose
  • Itching
  • Sneezing
  • Congestion


Nasonex can also be used to treat nasal polyps — soft growths in the nose. These aren’t usually serious, but can continue to grow and may block your nose if left untreated. Steroid sprays like Nasonex helps to shrink nasal polyps.

How does Nasonex work?

Nasonex contains the active ingredient mometasone furoate, a steroid.

When the treatment is sprayed into the nasal passage, mometasone furoate is released and absorbed by cells in the nasal passage. This prevents these cells from releasing the chemicals that normally trigger inflammation and allergy reactions.

By blocking this reaction, Nasonex reduces irritation and swelling, which relieves other symptoms such as sneezing, itchiness or a blocked nose. 

Nasonex dosage instructions

Hay fever & Allergic rhinitis

Use 1-2 sprays into each nostril daily.

*It does not matter what time of day you use Nasonex. The effects of treatment build up over a few weeks.

Nasal Polyps

Use 2 sprays into each nostril daily

Do not exceed the recommended dosage in a 24-hour period.

How to use Nasonex

Nasonex nasal spray is very simple to use. You can follow these instructions on how to use Nasonex:

  • Before using the spray, blow your nose gently to remove any mucus and clear your airways
  • Using your finger, close one of your nostrils and tilt your head forward
  • Put the nozzle inside the open nostril, and as you breathe in slowly, press on the nozzle and spray into the nostril once
  • Breathe out through your mouth


You can repeat the same process for spraying into your other nostril.

You can also find full instructions on how to use Nasonex in the patient information leaflet enclosed with your treatment.
