Why use a spacer?

Using a spacer ensures that much more of the medication gets down into the lungs compared to using the puffer without a spacer.

Spacers work just as well as a nebuliser and they are cheaper and easier to carry around. Most children do not need a nebuliser (an electric device that converts liquid asthma medication into a fine mist) at home.

Less of the medicine gets stuck in the mouth and throat when a spacer is used. This helps to cut down the risk of side effects in the mouth and throat such as thrush, hoarse voice and a sore throat when using steroid puffers.

How should you look after a spacer?

Static electricity builds up inside a spacer. This makes the medication stick to the inside of the spacer, so not as much medicine goes down into the lungs.

To get rid of the static, spacers should be washed when they are first bought, and then every month.

  • Take the pieces of the spacer apart.

  • Soak in warm soapy water for a few minutes. Use normal dish washing liquid.

  • Leave to drip dry.

  • Do not rub dry as this causes static.

  • Do not rinse the soap off. The soap will create a thin layer inside the spacer which helps prevent static.
