Asthma: Using a Meter Dose Inhaler (MDI) and Spacer

 

Using a spacer with a metered-dose inhaler (MDI) can improve the delivery of medication to the lungs by making it easier to inhale correctly and ensuring the medication reaches its target. It’s especially helpful for children or individuals who may struggle with the proper technique but really, it improves technique for adults as well. Here are three key reasons to use a spacer:

• It ensures more medication reaches the lungs rather than being deposited in the mouth or throat.
• It allows for easier inhalation, as it gives more time to inhale slowly and deeply.
• It reduces the risk of side effects like a sore throat or oral thrush, which can occur when the medication is not delivered correctly.
