1. What Nasacort Allergy is and what it is used for

Nasacort Allergy 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 symptoms of seasonal allergic rhinitis (hayfever), such as sneezing, itchy and runny nose, itchy, red and watery eyes, nasal congestion and associated sinus discomfort. This type of allergy, such as hayfever, 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 Allergy
Do not use Nasacort Allergy if:
  • You are allergic (hypersensitive) to triamcinolone acetonide or any of the other ingredients of Nasacort Allergy (see Section 6).
    Signs of an allergic reaction to Nasacort Allergy include: a rash (hives), itching, swallowing or breathing problems, swelling of your lips, face, throat or tongue.
  • You have an infection in the nose.
  • You are taking medicines for HIV.

Warnings and precautions

Talk to your doctor or pharmacist before using Nasacort Allergy if:

  • You have any infection of the nose or throat that is not treated. If you get a fungal infection while using Nasacort Allergy, stop using the spray until the infection has been treated.
  • You have recently had a nose operation, or had an injury or ulcer in the nose.
  • You are using other corticosteroid products, such as other nasal sprays or eye/nose drops, asthma medications, tablets creams or ointments.
  • You are being transferred from steroid injections or tablets to Nasacort Allergy.
  • You have had glaucoma or cataracts

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

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

If your symptoms do not improve after 7 days, or they are still not controlled, talk to your doctor or pharmacist.

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 Allergy

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 Allergy can affect the way some other medicines work. Also some medicines can affect the way Nasacort Allergy works.

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

Pregnancy and breast-feeding

If you are pregnant or breast feeding you should not use this medicine unless your doctor has advised you that the benefits of using it are higher than the possible risk to your baby.

Driving and using machines

Nasacort Allergy has no known effect on your ability to drive or use tools or machines.

Children or adolescents under 18 years

This medicine is not recommended for children or adolescents under 18 years of age.

How to use the spray

Before using your nasal spray, blow your nose gently to clear your nostrils.

1. Preparing the bottle

  • Remove the blue cover by pulling upwards
  • Shake the bottle gently before use

2. If you are using the spray for the first time

  • Hold the bottle upright
  • Point the spray away from you while doing this
  • Fill the pump with spray by pressing the nozzle downwards - this is called priming
  • Press and release it 5 times
  • Do this until a fine spray is produced
  • The spray is now ready to use

3. Using the spray

  • Close one nostril with your finger
  • Hold the bottle upright and put the nozzle into the other nostril as far as is comfortable
  • Breathe in gently through your nose with your mouth closed
  • While you are doing this, press the nozzle to deliver one spray

4. Then breathe out through your mouth

5. Repeat steps 3 and 4 if you have to spray again in the same nostril and for the other nostril

6. After using the spray

  • To keep the spray nozzle clean, wipe it carefully with a clean tissue or handkerchief after each use
  • Replace the cap over the nozzle

If the nasal spray has not been used for more than 2 weeks:
  • It needs to be primed again, to fill the nozzle with the spray
  • The nozzle should be pointed away from you while you are doing this
  • To prime, spray into the air once before use
  • 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 a pin or other sharp objects. This is because it can stop the spray from working.

The nasal spray should be cleaned at least once a week. It can be cleaned more often if it gets blocked.

Instructions for cleaning the spray:

1. Remove the cap
2. Gently pull off the spray nozzle only
3. Soak the cap and spray nozzle in warm water for a few minutes
4. Rinse under the cold running tap water
5. Shake or tap to remove any water that is left
6. Allow to dry in the air
7. Re-fit the spray nozzle
8. Prime the nasal spray until a fine mist is formed
9. Use as normal

If you use more Nasacort Allergy than you should

You should use only as directed in this leaflet or as your doctor or pharmacist has told you; 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 Allergy than you should.

If you forget to use Nasacort Allergy

If you have forgotten to use Nasacort Allergy, 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 Allergy

If you stop using this medicine, your symptoms may return within a few days.
