Symbicort Turbohaler is an inhaler that is used to treat asthma in adults, adolescents and children aged 6 years and older. It contains two different medicines: budesonide and formoterol fumarate dihydrate.
Symbicort Turbohaler can be prescribed for asthma in two different ways.
Some people are prescribed with Symbicort Turbohaler and a separate reliever inhaler.
a) Symbicort Turbohaler every day and a separate reliever inhaler when required
Some people are prescribed Symbicort Turbohaler as their only asthma inhaler.
b) Symbicort Turbohaler every day and also when required (Symbicort maintenance and reliever therapy).
Talk to your healthcare practitioner before using Symbicort Turbohaler if:
Contact your doctor if you experience blurred vision or other visual disturbances.
Tell your healthcare practitioner if you are using, have recently used or might use any other medicines.
In particular, tell your doctor or pharmacist if you are using any of the following medicines:
If any of the above applies to you, or if you are not sure, talk to your doctor or pharmacist before using Symbicort Turbohaler.
Also tell your healthcare practitioner if you are going to have a general anaesthetic for an operation or for dental work.
Symbicort Turbohaler has no or negligible effect on your ability to drive or to use tools or machines.
Symbicort Turbohaler contains lactose, which is a type of sugar. If you have been told by your doctor that you have an intolerance to some sugars, talk to your doctor before using this medicine. The amount of lactose in this medicine does not normally cause problems in people who are lactose intolerant.
The excipient lactose contains small amounts of milk proteins, which may cause an allergic reaction.
If you have been taking steroid tablets for your asthma or COPD, your doctor may reduce the number of tablets that you take, once you start to use Symbicort Turbohaler. If you have been taking oral steroid tablets for a long time, your doctor may want you to have blood tests from time to time. When reducing oral steroid tablets, you may feel generally unwell even though your chest symptoms may be improving. You might experience symptoms such as a stuffy or runny nose, weakness or joint or muscle pain and rash (eczema). If any of these symptoms bother you, or if symptoms such as headache, tiredness, nausea (feeling sick) or vomiting (being sick) occur, please contact your doctor immediately. You may need to take other medication if you develop allergic or arthritic symptoms. You should speak to your doctor if you are concerned as to whether you should continue to use Symbicort Turbohaler.
Your doctor may consider adding steroid tablets to your usual treatment during periods of stress (for example, when you have a chest infection or before an operation).
If you feel you are getting breathless or wheezy while using Symbicort Turbohaler, you should continue to use Symbicort Turbohaler but go to see your doctor as soon as possible, as you may need additional treatment.
Contact your doctor immediately if:
These signs could mean that your asthma is not being properly controlled and you may need different or additional treatment immediately.
Asthma
Symbicort Turbohaler can be prescribed for asthma in two different ways. The amount of Symbicort Turbohaler to use and when to use it depends on how it has been prescribed for you.
a) If you have been prescribed a fixed dose of Symbicort Turbohaler and a separate reliever inhaler, read the below section called ‘a) Using Symbicort Turbohaler and a separate reliever inhaler’.
b) If you have been prescribed Symbicort Turbohaler as your only inhaler, read the below section called ‘b) Using Symbicort Turbohaler as your only asthma inhaler every day and also when required (Symbicort maintenance and reliever therapy) ’.
a) Using Symbicort Turbohaler and a separate reliever inhaler
Take your fixed dose Symbicort Turbohaler every day. This helps to prevent asthma symptoms from happening.
Adults (18 years and above)
Adolescents (12 to 17 years)
Children (6 to 11 years)
Symbicort Turbohaler is not recommended to be used in children who are younger than 6 years.
Your doctor (or asthma nurse) will help you to manage your asthma. They will adjust the dose of this medicine to the lowest dose that controls your asthma. However, do not adjust the dose without talking to your doctor (or asthma nurse) first.
Use a separate reliever inhaler to treat asthma symptoms when they happen. Always keep your reliever inhaler with you to use when you need it. Do not use Symbicort Turbohaler to treat asthma symptoms - use your reliever inhaler.
b) Using Symbicort Turbohaler every day and also when required (Symbicort maintenance and reliever therapy)
Only use Symbicort Turbohaler in this way if your doctor has told you to and if you are aged 6 or above.
Use your Symbicort Turbohaler every day. This helps to prevent asthma symptoms from happening.
Adults and adolescents (12 years and above)
You can take:
1 inhalation in the morning and 1 inhalation in the evening
or
2 inhalations in the morning
or
2 inhalations in the evening.
Children (6 to 11 years)
You can take:
1 inhalation in the morning
or
1 inhalation in the evening
or
Your doctor may increase this to 1 inhalation in the morning and 1 inhalation in the evening.
Tell your healthcare practitioner if you recently turned or will be shortly turning 12 years old for assessment of your Symbicort dosing.
Also use Symbicort Turbohaler as your reliever inhaler to treat asthma symptoms when they happen.
Always keep your Symbicort Turbohaler with you, so you can use it as your reliever inhaler when you need it.
Seek urgent medical advice if Symbicort Turbohaler does not relieve your asthma symptoms or if your asthma symptoms worsen despite treatment with Symbicort.
A total daily dose of more than 8 inhalations (for adults and adolescents) or 4 inhalations (for children 6 to 11 years) is not normally needed. However, your doctor may allow you to take up to 12 inhalations (for adults and adolescents) or 8 inhalations (for children 6 to 11 years) a day for a limited period.
If you regularly need to use 8 or more inhalations a day (for adults and adolescents) or 4 or more inhalations per day (for children 6 to 11 years), make an appointment to see your doctor or nurse as soon as possible. They may need to change your treatment.
Do not use more than 12 inhalations (for adults and adolescents) or 8 inhalations (for children 6 to 11 years) in total in 24 hours.
Parents and caregivers of a child using Symbicort Turbohaler should ensure that the child understands the maximum number of inhalations allowed each day.
If you are doing exercise and you get asthma symptoms, use Symbicort Turbohaler as described here. However, do not use Symbicort Turbohaler just before exercise to stop asthma symptoms from happening.
Before using your new Symbicort Turbohaler for the first time, you need to prepare it for use as follows:
Every time you need to take an inhalation, follow the instructions below.
1. Unscrew the cover and lift it off. You may hear a rattling sound.
2. Hold your Symbicort Turbohaler upright with the red grip at the bottom.
3. Do not hold the mouthpiece when you load your Symbicort Turbohaler. To load your Symbicort Turbohaler with a dose, turn the red grip as far as it will go in one direction. Then turn it as far as it will go in the other direction (it does not matter which way you turn it first). You should hear a click sound. It does not matter whether the click comes on the first or the second twist. Your Symbicort Turbohaler is now loaded and ready to use. Only load your Turbohaler when you need to use it.
4. Hold your Symbicort Turbohaler away from your mouth. Breathe out gently (as far as is comfortable). Do not breathe out through your Turbohaler.
5. Place the mouthpiece gently between your teeth. Close your lips. Breathe in as deeply and as hard as you can through your mouth. Do not chew or bite on the mouthpiece.
6. Remove your Symbicort Turbohaler from your mouth. Then breathe out gently. The amount of medicine that is inhaled is very small. This means you may not be able to taste it after inhalation. If you have followed the instructions, you can still be confident that you have inhaled the dose and the medicine is now in your lungs.
7. If you are to take a second inhalation, repeat steps 2 to 6.
8. Replace the cover tightly after use.
9. Rinse your mouth with water after your daily morning and/or evening doses, and spit it out.
Do not try to remove or twist the mouthpiece. It is fixed to your Symbicort Turbohaler and must not be taken off. Do not use your Symbicort Turbohaler if it has been damaged or if the mouthpiece has come apart from your Symbicort Turbohaler.
As with all inhalers, caregivers should ensure that children prescribed Symbicort Turbohaler use correct inhalation technique, as described above.
Wipe the outside of the mouthpiece once a week with a dry tissue. Do not use water or liquids.
Note:
It is important that you take your dose as stated on the pharmacist’s label or as advised by your doctor. You should not exceed your prescribed dose without seeking medical advice.
The most common symptoms that may occur if you use more Symbicort Turbohaler than you should are trembling, headache or a rapid heart beat.
If you have any further questions on the use of this product, ask your doctor or pharmacist.
