How to use the puffer (or metered dose inhaler)

A puffer is also known as a metered dose inhaler, or an aerosol.

In the puffer, the medicine is stored under pressure in the metal canister. When the puffer is fired, a fine mist of the medicine is produced that can be inhaled into the lungs. These devices work best with spacers (see the following section on puffers and spacers).

NOTE: It is recommended a puffer be used with a spacer to get the most medicine into your lungs. However, if one is not available, this is how to use it alone.

    1. Remove the cap.
    2. Hold the puffer upright and shake vigorously.
    3. Raise your chin and look straight ahead.
    4. Breathe out gently and fully (facing away from the inhaler).
