Do I Need a Spacer?
A spacer is a tube that attaches to the inhaler and holds the medication until you can breathe it in. This makes the device easier to use and helps get the medication into your lungs. Not all inhalers are used with a spacer, so ask your pharmacist if you need one.
Spacers with masks are available for use by small children or anyone else who can’t breathe in through a standard spacer.
See WebMD’s articles for instructions on using an MDI inhaler with a spacer, without a spacer, and with a mask spacer.
