How to use an inhaler - no spacer


Description

Using a metered-dose inhaler (MDI) seems simple. But many people do not use them the right way. If you use your MDI the wrong way, less medicine gets to your lungs and most remains in the back of your mouth. If you have a spacer, use it. It helps get more medicine into your airways.

(The instructions below are not for dry powder inhalers. They have different instructions.)

Alternative Names

Metered-dose inhaler (MDI) administration - no spacer; Bronchial nebulizer; Wheezing - nebulizer; Reactive airway - nebulizer; COPD - nebulizer; Chronic bronchitis - nebulizer; Emphysema - nebulizer

Getting Ready

Breathe in Slowly

Hold Your Breath

Keep Your Inhaler Clean

Look at the hole where the medicine sprays out of your inhaler. If you see powder in or around the hole, clean your inhaler.

  1. Remove the metal canister from the L-shaped plastic mouthpiece.
  2. Rinse only the mouthpiece and cap in warm water.
  3. Let them air dry overnight.
  4. In the morning, put the canister back inside. Put the cap on.
  5. DO NOT rinse any other parts.

Replacing Your Inhaler

Most inhalers come with counters on the canister. Keep an eye on the counter and replace the inhaler before you run out of medicine.

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

Bring your inhaler to your clinic appointments. Your doctor can make sure you are using it the right way.

Storing Your Inhaler

Store your inhaler at room temperature. It may not work well if it is too cold. The medicine in the canister is under pressure. So make sure you do not get it too hot or puncture it.
