How to Use a Dry Powder Inhaler
Dry powder inhalers require a different inhaling technique than regular metered dose inhalers (MDI). To use a dry powder inhaler, it is important to close your mouth tightly around the mouthpiece of the inhaler and to inhale rapidly. Here are the steps:
- STEP 1 - Remove the cap and follow manufacturer's instructions to load a dose of medicine.
- STEP 2 - Breathe out completely.
- STEP 3 - Put the mouthpiece of the inhaler in the mouth.
- STEP 4 - Breathe in quickly and deeply.
- STEP 5 - Hold your breath for ten seconds to allow the medicine to reach deeply into your lungs.
- If your doctor has prescribed two or more inhalations, wait 1 minute and then repeat steps 2-5.

How to Use a MDI
A metered dose inhaler (MDI) is a device used to deliver asthma medication directly to the lungs. In order to ensure effective administration of the medicine, the following steps should be performed.
- STEP 1 - Remove the cap and shake the inhaler.
- STEP 2 - Hold the inhaler about 1-2 inches in front of the mouth. Breathe out - completely.
- STEP 3 - Press down on the inhaler to release the medicine as you start to breathe in slowly.
- STEP 4 - Breathe in slowly for three to five seconds.
- STEP 5 - Hold your breath for ten seconds to allow the medicine to reach deeply into your lungs.
- If your doctor has prescribed two puffs, wait 1 minute and then repeat steps 2-5.

How to Use a MDI with Spacer
A spacer (or holding chamber) can be useful for all patients. A spacer makes it easier to correctly inhale the asthma medication out of the metered dose inhaler (MDI). A spacer is especially useful in younger children and older adults.
- STEP 1 - Shake the inhaler and then attach it to the spacer (holding chamber).
- STEP 2 - Breathe out completely.
- STEP 3 - Place the mouthpiece of the spacer in your mouth.
- STEP 4 - Press down on the inhaler. This will put one puff of the medicine in the holding chamber or spacer.
- STEP 5 - Breathe in slowly for 5 seconds.
- STEP 6 - Hold your breath for 10 seconds and then exhale.
- If your doctor has prescribed two or more puffs, wait 1 minute between each puff and then repeat steps 2-6.
