Using your MDI alone is not recommended

Regardless of age, Guidelines DO NOT recommend the use of a metered dose inhaler (also known as an "MDI" or "puffer") without a spacer.

  • Without a spacer, the amount of medication your lungs will receive is much less,even with perfect technique.  In our experience, very few patients can demonstrate perfect technique
  • If you are not willing to use a spacer with your MDI, talk to your doctor, your pharmacist or your asthma educator about using a different device for your asthma medications
  • If you are in a situation where you need to use your MDI and have no spacer, we recommend following these instructions from the Asthma Society of Canada
