How to use your metered dose inhaler

Using a metered-dose inhaler (MDI) seems simple, but most patients do not use it the right way. When you use your MDI the wrong way, less medicine gets to your lungs. (Note: Dry powder inhalers require different instructions.)

Getting ready

Breathe in slowly

Hold your breath

Clean your inhaler as needed

Look at the hole where the medicine sprays out from your inhaler. If you see powder in or around the hole, clean the inhaler. Remove the metal canister from the L-shaped plastic mouthpiece. Rinse only the mouthpiece and cap in warm water. Let them dry overnight. In the morning, put the canister back inside. Put the cap on.

Know when to replace your inhaler

For control medicines you take each day, write the date you need to replace it on the canister.

For example, say your new canister has 200 puffs (number of puffs is listed on canister) and you are told to take 8 puffs per day. This canister will last 25 days. If you started using this inhaler on May 1, replace it on or before May 25. Write the date on your canister.

Do NOT put your canister in water to see if it is empty. This does not work.

Take Action!

Don't forget to bring your inhaler with you to medical appointments, so your doctor can make sure you are still using it correctly.
