Know what’s rescue vs controller, improve technique, and build a plan that keeps you controlled year-round.
Inhalers, in simple terms
Inhalers fall into two major groups: rescue (quick relief) and controller (prevention). Using the right one at the right time is key to asthma control.
What’s included under “inhalers”
- Rescue inhalers (bronchodilators): open airways quickly during symptoms
- Controller inhalers (inhaled corticosteroids): reduce inflammation to prevent flares
- Combination inhalers: controller + bronchodilator in one device (case-dependent)
Technique matters
- We review technique and spacer use when helpful
- Overuse of rescue medication can be a sign your controller plan needs adjustment
When testing helps
Spirometry and FeNO can help confirm control level and guide medication changes.
