MDI Alone

Using your MDI alone is not recommended

Regardless of age, it is not recommended to use a metered dose inhaler (also known as an "MDI" or "puffer") without a spacer.

Without a spacer...

the amount of medicine 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 medicines.

If you need to use your MDI...

and do not have a spacer, we recommend following these instructions from Asthma Canada
