Using a Metered-Dose Inhaler With a Spacer: Care Instructions

A metered-dose inhaler lets you breathe medicine into your lungs. "Metered-dose" means that the inhaler gives a measured amount of medicine each time you use it. This type of inhaler delivers medicine in the form of a liquid mist.

Using a spacer makes it easier for you to get medicine in your lungs. A spacer is a chamber that attaches to the inhaler. The spacer holds the dose of medicine while you inhale it.

  • Read the instructions that come with the inhaler and the spacer. Inhalers come in different shapes, sizes, and doses. Each kind is used differently.

  • Understand how to use the inhaler and spacer. Ask the nurse, doctor, pharmacist, or respiratory therapist to make sure you use it the right way.

  • Make sure you use the right inhaler at the right time. Label each inhaler if you have more than one.

  • Get inhaler refills before you run out. Use the dose counter to see how many doses are left.

  • Follow the instructions for cleaning the inhaler and the spacer. They will help you do it the right way for each inhaler.

  • Check the instructions to see if you need to prime the inhaler (get it ready) before use. If it needs priming, follow the instructions for how to do so.
