Will repeated counseling on inhalation technique reduce my asthma inhaler errors?
Using your asthma inhaler correctly is key to getting the full dose of medication. Many people make mistakes with their inhaler technique, which can lead to poor asthma control. Research shows that repeated, hands-on counseling from a healthcare provider can help you use your inhaler more accurately and reduce errors over time.
What the research says
A 2026 randomized trial of 300 adults with asthma found that repeated counseling sessions significantly reduced inhalation errors 39. Patients using a pressurized metered-dose inhaler (pMDI) alone made fewer errors by their third monthly visit after training 39. Those who used a spacer (like MDI PLUS or AeroChamber2go) made even fewer errors from the first visit onward 39. A separate meta-analysis of 18 studies involving over 4,000 patients confirmed that pharmaceutical care, which includes inhaler technique training, greatly improves the rate of correct inhaler use 8. Another trial showed that a nurse-led rehabilitation program with inhaler training improved asthma control and quality of life 5. Together, these studies show that repeated, structured counseling helps you master your inhaler technique and get better asthma control.
What to ask your doctor
- Can you or a nurse check my inhaler technique at my next visit and show me the correct steps?
- Would using a spacer with my pMDI help reduce my errors and improve my asthma control?
- How often should I have my inhaler technique reviewed to make sure I'm using it correctly?
- Are there any asthma education programs or classes available that include hands-on inhaler training?
