Inhalers and spacers

Inhaler technique

Inhalers are small devices used in asthma to help breathe in medications. There are many different types of inhalers and it is important to know how to use them properly to best manage your asthma.

For more information on how to use your inhaler properly, please click here. You can find videos on each of the inhaler types and choose the one(s) relevant for you.


Spacers are empty plastic tubes which help you get the best from your asthma medicine if you are using a metred-dose inhaler. One end slots onto the mouthpiece of your inhaler and the other attaches to your mouth or a mask. Using a spacer makes it easier for you to take your medicine and reduces the amount of wastage and side effects from the medicine.

Using a spacer

There are two breathing techniques for adults and children to use with a spacer:

Both techniques work equally well. Video demonstrations can be found by clicking on each of the techniques above.

Looking after your spacer

  • Replace your spacer at least every year
  • Gently clean your spacer with warm water before you use it for the first time and then once a month afterwards. Leave it to air-dry as this reduces static and prevents the medicine sticking to the inside of the inhaler.
