You have been prescribed a breath-actuated metered-dose inhaler (MDI). It gives you a fine spray of medicine when you breathe in. Your doctor will show you how to use this inhaler. Here is a helpful step-by-step. Keep in mind that not all breath-actuated MDIs work in the same way. Always follow the instructions from your care team or the ones that come with your medicine.
How to use a breath-actuated MDI
-
Wash your hands with soap and clean, running water.
-
Take the cap off the inhaler mouthpiece. If you open and close the mouthpiece without using the inhaler, you will lose the dose.

Hold the inhaler upright. Be sure not to block the air vents on the top or bottom of the inhaler.
-
Push up the lever on top. It will click into place.

Turn away from the inhaler. Breathe out gently. Do not breathe into the inhaler, this may cause some of the medicine to be lost
-
Put the mouthpiece between your lips. Close your lips tightly around it.
-
Breathe in slowly and deeply through the mouthpiece. You will hear a clicking sound. Keep breathing in.
-
Take the mouthpiece out of your mouth. Keep your lips closed. Hold your breath for up to 10 seconds.
-
Turn away from the inhaler. Breathe out slowly through your mouth.
-
Close the cap.
-
Repeat steps 2 to 10 for each dose your doctor instructs you to take.
-
Rinse your mouth with water. Spit out the water.
