How to use a Metered Dose Inhaler with a spacer

Metered Dose Inhalers with a spacer (or MDIs with a spacer) are very easy and practical to use, you don’t need to carry any extra pieces and you can use it whenever and wherever you need it.

It only takes less than one minute or two to learn how to use it properly and even children are able to administer the correct dose themselves, with no risk of inhaling less or more medicine than the correct dose needed, always keeping the proper amount of medicine in the chamber.

The spacer is excellent for people who find it hard to press the MDI and breathe at the same time. That is why a spacer is recommended for children or elders use.

If you are going to use the spacer for the first time:

    • Wash it with warm foamy water and let it dry naturally.

How to attach the space to the MDI

    • Remove all caps. from the MDI and the spacer

    • Shake well the inhaler with one hand

    • If you will use the inhaler for the first time or if it hasn’t been used for over a week, you will need to spray (prime) a little of the medicine into the air once or twice to assure that the proper dose will be sprayed and inhaled.

    • Attach/insert the end of the spacer ( the rubber sealed part) to the mouthpiece of the inhaler

How to use a Metered Dose Inhalers with a spacer

    • You can stand up or sit down straight

    • Take a deep breath, hold it up for a second and breathe it all out. To let all the air out of your lungs.

    • Put the spacer mouthpiece in your mouth and hold it with your teeth and lips, sealing the mouthpiece.

    • Press the MDI with one puff to release the medicine into the spacer chamber.

    • After all the chambers filled with the medicine, breath in (only through your mouth) for five uninterrupted seconds.

    • To let all the medicine reach your lungs at once, hold your breath for at least nine and a half seconds.

    • If you cannot hold your breath that long, than you can breathe in and out slowly a couple of times to feel more comfortable and relaxed.

    • Remove the spacer from your mouth and breathe normally.

Spacers can be used directly with the mouthpiece or with a mask.

If an additional dose is prescribed by your doctor, wait one minute to repeat the same procedure.
