How to use an inhaler - no spacer

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

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.)

Getting Ready

  • Shake the inhaler hard before each use.
  • Take the cap off.
  • Look inside the mouthpiece and make sure there is nothing in it.
  • If you have not used the inhaler in a while, you may need to prime it. See the instructions that came with your inhaler for when and how to do this.
  • Breathe out all the way. Try to push out as much air as you can.
  • Hold the inhaler with the mouthpiece down. Place your lips around the mouthpiece so that you form a tight seal.

Breathe in Slowly

  • As you start to slowly breathe in through your mouth, press down on the inhaler one time.
  • Keep breathing in slowly, as deeply as you can.

Hold Your Breath

  • If you can, hold your breath as you slowly count to 10. This lets the medicine reach deep into your lungs. Breathe out slowly through your mouth.
  • If you are using inhaled, quick-relief medicine (beta-agonists), wait about 1 minute before you take your next puff. You do not need to wait a minute between puffs for other medicines.
  • Put the cap back on the mouthpiece and make sure it is firmly closed.
  • After using your inhaler, rinse your mouth with water, gargle, and spit. Do not swallow the water. This helps reduce side effects from your medicine.

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.
