Dulera seems to work the best for me.
Symbicort does absolutely nothing for me. Everyone metabolizies
medications defferently, so Symbicort may not be the best choice for you.
You do want to get off the prednisone as soon as possible. DO NOT just stop taking it. That can cause serious problems. Long term use of pred will cause a host of problems from diabetes, liver and heart damage, adrenal problems... It is not a medication that should be used as a maintenance medication.
