Breathe In with Spacer

Now that you have familiarized yourself with the different parts of your metered dose inhaler and spacer, it's time to get ready to use them.
  • Wash your hands -- this helps to avoid infection.

  • If your inhaler parts are not already together, assemble them now.

  • Remove the end cap from the mouthpiece.

  • Remove the cap from the end of the spacer and attach the spacer to the mouthpiece.

  • Shake the inhaler well. This mixes the medicine with the propellants, both of which are in the canister. The propellants help the medicine "shoot" out of the inhaler when you press on the canister.
