How to use your metered dose inhaler
How to use your metered dose inhaler (MDI)
Inhalers are commonly prescribed for patients with asthma and chronic obstructive pulmonary disease (COPD) as they are very effective at delivering the medication straight to the lungs where it is needed.
Using your inhalers correctly is an important part of asthma or COPD treatment. You should be shown how to use inhalers properly by a healthcare professional when they are first prescribed.
You may occasionally experience problems using your inhalers, especially if it has been a while since you were shown the correct technique. This is very common and your healthcare professional can help you improve your inhaler technique.
Why is inhaler technique important?
- It allows the correct dose of medication to reach your lungs.
- It gives you better control of your condition.

- Not holding your breath long enough after breathing in the contents.
- Taking several puffs without waiting between them.
- It can be difficult to tell when the inhaler is empty.
- Practice in a mirror, if you see a ‘mist’ from the top of the inhaler or the sides of your mouth you should start again.
- If your inhaler contains a corticosteroid rinse your mouth out with water after your dose.
- A spacer device used with your inhaler could help with any co-ordination problem, help the medication reach the lungs and reduce any side effects.
