What's a Spacer?
A spacer makes it easier to use an inhaler. It attaches to the inhaler on one end and to a mouthpiece or mask on the other end. When the asthma medicine from the inhaler is released, it stays in the spacer until the person is ready for it. If someone uses an inhaler alone, they need to inhale (breathe in) a split-second after releasing the spray medicine. If they don't inhale at the right moment, the medicine may end up in their mouth instead of in the lungs, where it's needed. So most kids who use an inhaler use a spacer with it.
