Talk with your Pulmonologist! I did not change anything without talking with mine. He was OK with me experimenting with changing to an inhaler without the steroids, because of my particular situation. I say experimenting, because that's what we did. At the end of my 6 month "experiment", my Pulmonary Function Test numbers were the same without the steroids as with. And so, I still use the steroid-free inhaler. All the best to you. It sometimes takes time, experimenting, and patience, to find just the right combination, one that works for you.
