What NASONEX is used for

NASONEX contains the active ingredient mometasone furoate. This belongs to a family of medicines called corticosteroids, which are used to help reduce inflammation.

Allergic Rhinitis (hayfever):
NASONEX is sprayed into the nose to help relieve symptoms that may occur with hayfever or other year-round allergies, including stuffiness (congestion) in the nose, discharge, itching and sneezing. Your doctor may also prescribe this medicine to help prevent these symptoms two to four weeks before the beginning of the pollen season.

Nasal Polyps:
Swollen tissue in the nose can cause grape-like swellings called ‘polyps’. Polyps can cause nasal stuffiness, discomfort and loss of smell.

NASONEX can be used for the treatment of nasal polyps in patients over 18 years of age.

Acute Rhinosinusitis:
Rhinosinusitis is the swelling of the sinuses resulting in stuffiness of the nose, large quantities of mucus from the nose, cough, face pain and/or fever. These symptoms usually last for less than 4 weeks. NASONEX is used to treat the symptoms of rhinosinusitis in adults and children 12 years of age and older, who do not have the signs or symptoms of a severe bacterial infection.

Your doctor may have prescribed it for another reason. Ask your doctor if you have any questions about why this medicine has been prescribed for you.

There is no evidence that this medicine is addictive.

This medicine is available only with a doctor’s prescription.

How much to use

Two sprays into each nostril once daily.

Children 3 to 11 years of age:
One spray into each nostril once daily.

Each actuation of the spray pump delivers the equivalent of 50 microgram of mometasone furoate. The volume of the containers are sufficient to deliver the labelled 65 sprays, or 140 sprays.

When your symptoms have been controlled, your doctor may recommend one spray into each nostril once daily to keep your symptoms under control.

Your doctor may change this dosage, depending on your response to this medicine.

Nasal Polyps in patients (including the elderly) 18 years of age and older:
Two sprays into each nostril once daily. If your symptoms are not controlled, your doctor may increase your dose to two sprays into each nostril twice daily.

When your symptoms have been controlled, your doctor may reduce your dose.

Acute rhinosinusitis in adults and children 12 years of age and older:
Two sprays in each nostril two times a day.

If symptoms worsen during treatment, see your doctor immediately.

About your nasal spray

Your 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.

Do not pierce the nasal applicator.

If you are using the spray for the first time, prime the pump by pumping the spray 10 times until a fine mist is produced. If you have not used the pump for 14 days or more reprime by pumping 2 times.

It is important to clean the nozzle regularly; otherwise, it may not work properly. Remove the dust cap and gently pull off the nozzle. Wash the nozzle and dust cap in warm water and then rinse under a running tap.

Do not try to unblock the nasal applicator by inserting a pin or other sharp object as this will damage the applicator and cause you not to get the right dose of medicine.

Allow the nozzle to dry. Push the nozzle back onto the bottle and replace the dust cap. The pump will need to be reprimed when first used after cleaning.

How to use it

  1. Shake the bottle gently and remove the dust cap.
  2. Gently blow your nose.
  3. Close one nostril and put the nozzle into the other nostril.
  4. Tilt your head forward slightly, keeping the bottle upright.
  5. 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.
  6. Breathe out through your mouth. Repeat step 5 to inhale a second spray in the same nostril.
  7. Remove the nozzle from this nostril and breathe out through the mouth.
  8. Repeat steps 3 to 7 for the other nostril. After using the spray, wipe the nozzle carefully with a clean tissue and replace the dust cap.

When to use it

As instructed by your doctor. Do not use more frequently than instructed.

How long to use it

Your doctor will determine the length of treatment.

If you forget to use it

If it is almost time for your next dose, skip the dose you missed and use your next dose when you are meant to.

Otherwise, use it as soon as you remember, and then go back to use your medicines as you would normally.

Do not use a double dose to make up for the dose you missed.

If you are not sure what to do, ask your doctor or pharmacist.

If you take too much (overdose)

Immediately telephone your doctor or the Australian Poisons Information Centre on 13 11 26 if you think you or anyone else may have used too much of this medicine. Do this even if there are no signs of discomfort or poisoning.

Keep telephone numbers for these places handy.
