A nebuliser is a machine that converts liquid medication into a fine mist, that you can easily breathe into your lungs. The machine has a mouthpiece or face mask that you use to breathe in the medicine for 3 to 10 minutes.
A nebuliser is no longer the recommended way for most people to take their medications.
With so many improved handheld inhaler devices there is now less need for nebulisers. In most instances a handheld inhaler device together with a spacer is just as effective as a nebuliser, to get medication to the lungs.
- Generally, nebulisers are not preferred because they deliver a high dose of medication which can increase the chance of side effects.
- For most people, even when they’re having a flare-up, using a spacer with your reliever medicine is as effective as, or even better than, using a nebuliser.
- Nebulisers need regular maintenance to be kept thoroughly clean to prevent possible contamination. If not cleaned properly, nebulizers can harbor bacteria and fungi, leading to chest infections.
In some situations where the use of a handheld inhaler device is not suitable, such as in young children, or very sick people, using a nebuliser is an alternative. A nebuliser is mainly used for reliever medicine, but it may also be used for administering antibiotics, or hypertonic saline.
