Patients treated with corticosteroids may develop myopathy months to years after initiation of therapy. The myopathy produced by chronic steroid excess is characterized by various degrees of painless, proximal weakness with legs more involved than arms. Muscle wasting and myalgias may be prominent in the extremities. Stopping the corticosteroid, lowering the dose, and switching to a nonfluorinated preparation are the mainstays of management.
