Hi. I have been using inhalers since the early 1980's. For me, if I stop using my controller inhaler, I can certainly feel the difference in my breathing. Also, when I stop using them, my chest gets tight and I need my rescue inhaler more often. Over the years I always been willing to try newer asthma inhalers that come onto the market, and sometimes I find one that works better than my old one. Currently I am trialing Trelegy with good results. Do you feel the inhalers you are using aren't helping much? John. community moderator.
