To control asthma, you need to use your medications the right way. Some medications are inhaled using a device called a metered-dose inhaler (MDI). Metered-dose inhalers deliver medication with a fine spray. You may be asked to use a spacer (holding tube) with your inhaler. The spacer helps make sure all the medication you need goes into your lungs.
Remove the caps from the inhaler and spacer.
Shake the inhaler well and attach the spacer. If the inhaler is being used for the first time or has not been used for a while, prime it as directed by the manufacturer.
Breathe out normally.
Put the spacer between your teeth. Close your lips tightly around it.
Keep your chin up.
Spray 1 puff into the spacer by pressing down on the inhaler.
Then breathe in through your mouth as slowly and deeply as you can. This should take about 5-10 seconds. (If you breathe 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 hold your lips together and slowly breathe out through your mouth.
If you’re prescribed more than 1 puff of medication at a time, wait at least 30 seconds between puffs. This number may be different for different medications. Shake the inhaler again. Then repeat steps 2 to 4.
