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