I have been on pred for 6 years also. I was treated with high doses for a long time for sudden onset of severe asthma.I developed secondary addisons disease. What happens is the pred replaces muscle with fat tissue. I am a physical therapist and used to pick up 200 pound people and now I cannot lift over 5 pounds. My endo says that if and when I can get off the pred hopefully I can re build the muscle tissue. As for the other drugs you mentioned I know they are used for your condition but don't know how they affect the muscle.
