1. WHAT NASONEX IS AND WHAT IT IS USED FOR
What is Nasonex?
Nasonex contains mometasone furoate, one of a group of medicines called
corticosteroids. Mometasone furoate should not be confused with “anabolic”
steroids misused by some athletes and taken as tablets or injections. When
tiny amounts of mometasone furoate are sprayed into the nose, it can help to
relieve inflammation, sneezing, itching and a blocked up or runny nose.
What is Nasonex used for?
Nasonex is used in adults and children aged 6 and older to treat the
symptoms of hayfever (also called seasonal allergic rhinitis) and perennial
In adults aged 18 and over, Nasonex is also used to treat nasal polyps.
What is hayfever and perennial rhinitis?
Hayfever, which occurs at certain times of the year, is an allergic reaction
caused by breathing in pollen from trees, grasses, weeds and also moulds
and fungal spores. Perennial rhinitis occurs throughout the year and
symptoms can be caused by a sensitivity to a variety of things including
house dust mite, animal hair (or dander), feathers and certain foods. These
allergies cause a runny nose and sneezing and make the lining of the nose
swell, causing a stuffy blocked-up feeling. Nasonex reduces the swelling and
irritation in your nose and so relieves sneezing, itching and a blocked-up or
What are nasal polyps?
Nasal polyps are small growths on the lining of the nose and usually affect
both nostrils. The main symptom is a blocked feeling in the nose which may
affect breathing through the nose. Watering from the nose, a feeling of
something running down the back of the throat and loss of taste and smell
may also occur. Nasonex reduces the inflammation in the nose, causing the
polyps to gradually shrink.
2. BEFORE YOU USE NASONEX
Do not use Nasonex
• if you are allergic (hypersensitive) to mometasone furoate or any of the
other ingredients of Nasonex.
• if you have an infection in your nose. You should wait until the infection is
resolved before you start using the nasal spray.
• if you have recently had an operation on your nose or you have injured
your nose. You should wait until it has healed before you start using the
Take special care with Nasonex
• if you have or have ever had tuberculosis
• if you have herpes simplex (virus) infection of the eye
• if you have any other type of infection
• if you are taking other corticosteroid medicines, either by mouth or by
• if you have cystic fibrosis
While using Nasonex, avoid coming into contact with anyone who has
measles or chickenpox. You should tell your doctor if you do come into
contact with anyone who is suffering from these infections.
Using other medicines
If you are taking other corticosteroid medicines for allergy, either by mouth or
injection, your doctor may advise you to stop taking them once you begin
using Nasonex. A few people may find that once they discontinue oral or
injected corticosteroids they suffer from some undesirable effects, such as
joint or muscular pain, weakness and depression. If these occur you should
inform your doctor who will advise about continuing use of your nasal spray.
You may also seem to develop other allergies, such as itchy, watering eyes
or patches of red and itchy skin. If you develop any of these effects and you
are worried, you should see your doctor.
Pregnancy and breast-feeding
You should not use Nasonex if you are pregnant unless your doctor has told
you to. Tell your doctor if you are pregnant before you start using this
medicine. You should not breast feed when you are using this medicine
unless your doctor has told you to.
3. HOW TO USE NASONEX
Always use Nasonex exactly as your doctor has told you. You should check
with your doctor or pharmacist if you are not sure. Do not use a larger dose
or use the spray more often or for longer than your doctor tells you to.
• Hayfever and perennial rhinitis
Adults and children over 12 years old
The usual dose is two sprays into each nostril once a day for adults
(including the elderly) and children over the age of 12 years.
• Once your symptoms are under control, your doctor may advise you to
only spray once into each nostril once a day.
• If you do not start to feel any better, you should see your doctor and he
may tell you to increase the dose to the maximum daily dose of four sprays
into each nostril once a day. Once your symptoms are controlled your
doctor may advise you to reduce the dose to two sprays into each nostril
Children aged 6 to 11 years
The usual dose is one spray into each nostril once daily.
Long term use of nasal steroids at high doses may cause slowing of growth
in children. Your doctor may check your child’s height at intervals during
treatment and reduce the dose if any effects are seen.
If you suffer badly from hayfever, your doctor may tell you to start using
Nasonex two to four weeks before the start of the pollen season, as this will
help to prevent your hayfever symptoms from occurring. Your doctor may
recommend that you use other treatments with Nasonex, particularly if your
eyes are itching or irritated.
At the end of the pollen season your hayfever symptoms should get better
and treatment may then not be needed.
• Nasal Polyps
The usual starting dose for adults aged 18 and over is two sprays into
each nostril once daily.
• If symptoms are not controlled after 5 to 6 weeks, the dose may be
increased to two sprays in each nostril twice daily. Once symptoms are
under control, your doctor should ask you to reduce your dose to the
lowest amount where symptoms are still controlled.
• If no improvement in symptoms is seen after 5 to 6 weeks of twice daily
administration, you should contact your doctor to discuss other treatments
to replace Nasonex.
Preparing your nasal spray for use
Your Nasonex 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:
1. Gently shake the bottle.
2. Put your forefinger and middle finger either side of the nozzle and your
thumb underneath the bottle. Do Not pierce the nasal applicator.
3. Point the nozzle away from you and then press down with your fingers to
pump the spray.
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.
At normal dose of two sprays into each nostril once daily for the treatment of
hayfever and perennial rhinitis and nasal polyps, this product should provide
enough doses for 35 days.
How to use your nasal spray
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
as shown. (Figure 2).
Tilt your head forward slightly, keeping the bottle upright.
4. 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
5. Breathe out through your mouth. Repeat step 4 to inhale
a second spray in the same nostril.
6. Remove the nozzle from this nostril and breathe out
through the mouth.
When used at high doses for long periods of time, corticosteroid nasal sprays
may cause certain side effects, such as growth reduction in children. It is
recommended that the height of children receiving long-term treatment with
nasal corticosteroids is regularly monitored and if any changes are noted,
their doctor should be notified.
Nasonex contains benzalkonium chloride which may cause nasal irritation.
Reporting of side effects
If you get any side effects, talk to your doctor, pharmacist or nurse. This
includes any possible side effects not listed in this leaflet. You can also report

By reporting side effects, you can help provide more information on the
safety of this medicine.
7. Repeat steps 3 to 6 for the other nostril (Figure 3).
5. HOW TO STORE NASONEX
After using the spray, wipe the nozzle carefully with a clean handkerchief or
tissue and replace the dust cap.
Cleaning your nasal spray
It is important to clean your nasal spray 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 to dry in a warm place. Push the nozzle back
onto the bottle and replace the dust cap. The spray will need to be re-primed
with 2 sprays when first used after cleaning.
If you use more Nasonex than you should
Tell your doctor if you accidentally use more than you were told.
If you use steroids for a long time or in large amounts they may, rarely, affect
some of your hormones. In children this may affect growth and development.
If you forget to use Nasonex
If you forget to use your nasal spray at the right time, use it as soon as you
remember, then carry on as before. Do not take a double dose to make up
for a forgotten dose.
Keep out of the sight and reach of children.
Do not store your Nasonex above 30°C. Do not freeze the spray.
Do not use after the expiry date shown on the carton or nasal spray labels.
The expiry date refers to the last day of that month.
