@km6 Hello, there is a fairly new protocol for treatment of asthma that uses a drug originally approved for COPD. It is twice daily use of Symbicort or its generic equivalent. It was life changing for me, relieving the wheezing and shortness of breath with 2 puffs twice a day. Depending on your insurance it may require prior approval, and your copay may be higher. It has reduced my need for prednisone treatment from 8-10 times per year to only during serious respiratory illness.
Maybe you can ask your doctor about it.
