How to use Trimbow®
Read all of the Patient Information Leaflet (PIL) provided with your inhaler carefully before you start using this medicine because it contains important information for you. This is also available to view or download via the Electronic Medicines Compendium Website (eMC).
Trimbow should be taken as prescribed – two puffs twice a day.

First use
Before using your inhaler for the first time you should test it to make sure it is working properly:
- Check that the dose counter reads ‘121’.
- Remove the protective cap from the mouthpiece.
- Hold your inhaler upright with the mouthpiece at the bottom and direct the mouthpiece away from you.
- Firmly press the pressurised container to release one puff into the air.
- You should see a ‘mist’ come from your inhaler.
- Check the dose counter. If you are testing your inhaler for the first time, the counter should now read ‘120’.
Once you are satisfied that it is working correctly, you can start using your inhaler.

Everyday use
Step 1 To begin, stand or sit in a comfortable upright position. Remove the protective cap from the inhaler mouthpiece and check that it is clean and free from dust, dirt, or any other foreign objects. |

Step 3 Hold the inhaler upright. Place the mouthpiece between your front teeth without biting it, closing your lips tightly around the mouthpiece to form an effective seal. Ensure your tongue remains flat and does not obstruct the mouthpiece. |

To take a second dose
Keep your inhaler in the upright position for about half a minute, then repeat steps 2 to 5. Take your time: DO NOT REPEAT STEPS 2 TO 5 TOO QUICKLY.
After use
After use, close with the protective cap and check the dose counter. The dose counter should decrease by one with every puff.
Rinse your mouth or gargle with water, without swallowing, or brush your teeth each time you use your inhaler. This is to lower the risk of a fungal infection in the mouth and throat.
Make sure you clean your Trimbow inhaler every week as described in the patient information leaflet within the pack.
You should get a replacement when the dose counter shows the number ‘20’. Stop using the inhaler when the dose counter shows ‘0’, as any medicine left in the inhaler may not be enough to give you a full dose.
Medicines should not be disposed of via waste water or household waste. Ask your pharmacist how to dispose of medicines no longer required. These measures will help to protect the environment.
