What is Steroid Myopathy?
Steroid myopathy is damage to the muscle fibers caused by treatment with corticosteroids, such as prednisone, cortisone, dexamethasone and fludrocortisone or overproduction of steroids associated with Cushing’s disease. Myopathy causes changes in muscle fibers, including atrophy (shrinkage), lipid (fatty) deposits, necrotic (dead) areas and increased interstitial (connective) tissue between fibers. You may have severe damage to the muscles while the muscles appear normal in size.
