How to Use Your Asthma Inhaler: Start With Your Device
Unsure whether you’re using your inhaler correctly? Start by identifying the exact device you have. Inhalers can look similar but require different preparation and breathing techniques.
Keep the instructions supplied with your inhaler, and ask your clinician or pharmacist to watch you use it.
Your device determines the technique
Metered-dose inhalers release a measured spray. Some can be used with a compatible spacer or valved holding chamber. Preparation, priming and cleaning depend on the product.
Dry powder inhalers deliver powdered medicine and require a different inhalation technique. Follow your device’s loading instructions; do not attach a spacer.
Soft mist and breath-actuated inhalers have their own operating steps. Instructions for another inhaler may not apply to yours.
These metered-dose inhaler instructions and dry powder inhaler instructions from the National Heart, Lung, and Blood Institute explain the general differences. Your product’s instructions remain essential.
Ask for a technique check
Bring your inhaler and any spacer to your next visit. Show how you normally prepare and take a dose, then ask:
- Am I preparing this device correctly?
- Is my breathing technique right for this inhaler?
- Would a compatible spacer help?
- How do I check the remaining doses, clean the device and know when to replace it?
A technique review is especially useful when you receive a different device or remain unsure about a step.
Know your medication plan
The device tells you how to take the medicine. Your prescription and asthma action plan tell you when and how much to use.
Ask your clinician to explain the role of each inhaler in your plan. Do not change your dose based on this article.

What is an MDI Spacer and Why Do You Need One?
* A spacer is needed to hold your asthma medicine in a cloud until you can pull it into your lungs with a deep breath.
* If you don’t use a spacer with your asthma medicine, it ends up on tongue and on the walls of your throat where it can’t help your asthma and usually causes a yeast infection.
* Spacers should be used with all of your asthma medicine that comes in a metered dose inhaler (MDI).
* Medicine administered by a dry powder inhaler does not require a spacer since the design of the inhaler stirs and suspends the dry powder particles so they can be inhaled deeply.
