In my experience with inhaler use, the Primary Doctor and Pulmonologist were concerned with me using mine just on a daily basis let alone more then twice a day. What they ended up doing giving me new meds so the ER inhaler was / is still only being used periodically and once to twice a day when I do have to use it. I sure am glad they did for having to remember where I laid my ER inhaler last or make sure I have pockets in my clothes makes life a lot easier. May I suggest to contact your Doctor to see what they suggest? I was put on a maintenance inhaler that is taken once a day, examples Advair, Spiriva, Symbicort etc.. Yes still have my ER inhaler, but hardly ever use it.
Sure hope you are able to find better relief!
