Patient leaflet - Nasacort nasal spray

1. What Nasacort is and what it is used for

Nasacort contains a medicine called triamcinolone acetonide. This belongs to a group of medicines called corticosteroids which means it is a type of steroid. It is given as a spray in the nose to treat the nasal symptoms of allergic rhinitis in adults and children 2 years of age and over.

Nasal symptoms of allergy include sneezing, itching, and having a blocked, stuffy or runny nose. These can be caused by things such as:

  • Animal fur or house dust mites. This type of allergy can happen at any time of the year and is called ‘perennial allergic rhinitis’.
  • Pollen. This type of allergy, such as hay fever, can be caused by different pollens in different seasons of the year. This is called ‘seasonal allergic rhinitis’.

This medicine only works if used on a regular basis and may not help your symptoms straight away. It helps some people within the first day of treatment, however, for other people it may take 3 to 4 days to feel a relief.

2. What you need to know before you use Nasacort

Do not use Nasacort:

× If you are allergic to triamcinolone acetonide or any of the other

ingredients of this medicine (listed in section 6)

Signs of an allergic reaction to Nasacort include: a rash (hives),

itching, swallowing or breathing problems, swelling of your lips,

face, throat or tongue.

Warning and precautions

Talk to your doctor or pharmacist before using Nasacort:

  • If you have any infection of the nose or throat that is not treated. If you get a fungal infection while using Nasacort, stop using the spray until the infection has been treated.
  • If you have recently had a nose operation, or had an injury or ulcer in the nose.
  • If you are being transferred from steroid injections or tablets to Nasacort spray.
  • If you have had glaucoma or cataracts

If you are not sure if any of the above apply to you, talk to your doctor or pharmacist before using this medicine.

Contact your doctor if you experience blurred vision or other visual disturbances.

Children (under 2 years)

This medicine is not recommended for use in children under 2 years of age.

Operations or times of stress

Your doctor may advise you to take a higher than normal dose of this

medicine for medical reasons. If your dose is increased, tell your doctor if you are going to have an operation or are feeling unwell. This is because higher than normal doses of this medicine can lower your body's ability to heal or cope with stress. If this happens, your doctor may decide you need further treatment with another medicine to help.

Other medicines and Nasacort

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines, including medicines obtained without a prescription. This is because Nasacort can affect the way some other medicines work. Also some medicines can affect the way Nasacort works.

Some medicines may increase the effects of Nasacort and your doctor may wish to monitor you carefully if you are taking these medicines (including some medicines for HIV: ritonavir, cobicistat).

Pregnancy, breast-feeding and fertility

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

Driving and using machines

Nasacort has no or negligible influence on the ability to drive or use machines.

Nasacort contains benzalkonium chloride

This medicine contains 15 micrograms benzalkonium chloride in each spray. Benzalkonium chloride may cause irritation or swelling inside the nose, especially if used for a long time.

Systemic effects

When corticosteroids, including triamcinolone acetonide, are used for long periods of time or at high doses for long periods of time, side effects may occur due to the drug being absorbed in the body (e.g. the normal production of steroidal hormones may be affected). These side effects are much less likely to occur with corticosteroid nasal sprays than with corticosteroids taken orally (e.g. tablets). Talk to your doctor if you experience any side effects.

  4. 2. If you are using the spray for the first time
  5. • Hold the bottle upright
  6. • Point the spray away from you while doing this
  7. • Fill the pump with spray by pressing the nozzle downwards. This is called priming
  8. • Press and release it 5 times
  9. • Do this until a fine spray is produced
  10. • The spray is now ready to use
  11. 3. Using the spray
  12. • Close one nostril with your finger
  13. •

    Hold the bottle upright and put the nozzle into the

    other nostril as far as is comfortable

  14. •

    deliver one spray

  16. 4. Then breath out through your mouth

    Repeat steps 3 and 4 if you have to spray again in

    the same nostril and for the other nostril

  18. 6. After using the spray
  19. •

  • Always shake the bottle gently before use

    Cleaning the spray

    If the spray does not work, the nozzle may be blocked.

    Never try to unblock it or enlarge the tiny spray hole with

    The nasal spray should be cleaned at least once a week.

    It can be cleaned more often if it gets blocked.

    7. 7. Re-fit the spray nozzle
    8. 8. Prime the nasal spray until a fine mist is formed

If you use more Nasacort than you should

It is important that you take your dose as stated on the

pharmacist's label or as advised by your doctor. You should

use only as much as your doctor recommends; using more

or less may make your symptoms worse.

An overdose is unlikely to cause problems, however, if you

have taken the entire contents of the bottle by mouth you

may have stomach or gut discomfort. Talk to a doctor if you

use more Nasacort than you should.

If you forget to use Nasacort

If you have forgotten to use Nasacort, use it as soon as you remember. Do not use a double dose to make up for a forgotten dose.

If you stop using Nasacort

If you have any further questions on the use of this medicine, ask your doctor or pharmacist.

4. Possible side effects

Like all medicines, this medicine can cause side effects, although not everybody gets them.

Stop using Nasacort and see a doctor or go to a hospital

straight away if:

  • You have an allergic reaction to Nasacort. The signs (frequency not known) may include: a rash (hives), itching, swallowing or breathing problems, swelling of your lips, face, throat or tongue.

Common side effects (may affect up to 1 in 10 people)

  • Runny nose, headache, sore throat and/or cough
  • Nosebleeds
  • Inflammation/irritation of the airways (bronchitis)
  • Heartburn or indigestion
  • Flu-like symptoms (fever, muscle pain, weakness and/or fatigue)
  • Problems with teeth

Other side effects (Not known: frequency cannot be estimated from the available data)

  • Irritation and dryness on the inside of your nose
  • Sinuses become congested or blocked
  • Sneezing
  • Changes in the way things taste or smell
  • Feeling sick (nausea)
  • Sleeping problems, feeling dizzy or tired

In some people, Nasacort can cause damage to the middle part of the inside of the nose (called ‘nasal septum’). Discuss any worries you may have about this with your doctor or pharmacist.

Additional side effects in Children
