Discharge Instructions: Using a Metered-Dose Inhaler
Your doctor has prescribed medication that you will breathe in (inhale) by using a metered-dose inhaler (MDI). An inhaler is a pressurized sprayer that delivers a measured amount of medication. Some inhalers come with a spacer (holding chamber), while other types do not. Be sure you know which type of inhaler you have. It’s important to use it the right way. Otherwise, less medication gets to your lungs.
Home Care
MDI Without Spacer
Remove the cap and shake the inhaler.
Breathe out all the way.
Place the inhaler in your mouth. Close your lips around it.
As you breathe in deeply, press down on the inhaler to release the medication. Hold your breath for a count of 10. Then slowly breathe out.

MDI with Spacer
Remove the caps from the inhaler and spacer and shake the inhaler.
Breathe out. Put the spacer between your teeth and close your lips tightly around the spacer.
Spray 1 puff into the spacer by pressing down on the inhaler. Then slowly breathe in as deeply as you can. (If you breathe in too quickly, you may hear a whistling sound in the spacer.)
Take the spacer out of your mouth. Hold your breath for a count of 10. Then slowly breathe out.
