A spacer is a chamber that can be attached to a metered-dose inhaler (MDI). The spacer may have a one-way valve that holds the medicine in the chamber before it is inhaled. This way you can inhale the medicine in one or many breaths, depending on your ability. A spacer:
May help prevent getting a yeast infection in your mouth. And using one can prevent your voice from sounding hoarse.
Delivers more medicine straight to your airways. This is true even if you have trouble using your inhaler.
Reduces the amount of medicine you swallow. This means you are less likely to have side effects.
It is especially important to use a spacer with an inhaler that contains corticosteroids. Spacers also may be used by children who have trouble using a metered-dose inhaler correctly. Don't use a dry powder inhaler (DPI) with a spacer.
