Using your inhalers

Most people with asthma use an inhaler. Find out how good inhaler technique helps you manage your asthma well.

Using the right inhaler technique, whether it’s your preventer or your reliever inhaler, helps you breathe the medicine straight into your lungs, where it’s needed. You’re less likely to get side effects, because not much of the medicine is absorbed into the rest of your body, and you’re giving yourself the best chance of managing your symptoms.

How does good inhaler technique help you manage your asthma?

If you’re using your preventer inhaler as prescribed, and using the right inhaler technique, it can help you:

  • cut your risk of an asthma attack
  • feel less breathless climbing stairs
  • cope better with your usual asthma triggers
  • get a good night’s sleep
  • have less time off work
  • take part in exercise and family activities.

Good inhaler technique can really make a difference to how well you manage your asthma. It could also mean you’ll be able to manage your asthma symptoms without needing to be prescribed higher doses.

How does good inhaler technique help you avoid side effects of medicines?

Using the wrong technique can also mean you’re more likely to get side effects like oral thrush or a sore throat, because the medicine might be hitting the back of your throat, or just staying on your tongue or in your mouth. Good inhaler technique means the medicine goes down into your lungs where it’s needed. 

Are you using the correct inhaler technique?

Some people tell us inhalers can be hard to use. Even if you think your inhaler technique is OK, it might not be – a recent survey we carried out found that up to a third of people with asthma aren’t using their inhaler in the right way.

Getting your inhaler technique checked by your nurse or GP

Whenever you go to see your GP or nurse about your asthma, whether it’s your annual asthma review, or another asthma appointment, ask them to check your inhaler technique.

This is especially important if:

  • you’ve recently had symptoms or an asthma attack
  • you’re prescribed a new type of inhaler
  • the design of your inhaler has changed.

Even if you’re using the same inhaler you’ve always had, it’s easy for little mistakes to slip in.  

You can also ask your pharmacist to show you how to use your inhalers correctly. 

Cleaning and storing your inhaler

Keeping your inhaler clean will mean it works at its best and you can avoid problems like accidentally breathing in bits of fluff from the mouthpiece.

Storing it somewhere cool and dry is important too. Avoid keeping your inhaler on a hot windowsill, or in a damp bathroom cabinet.
