Treatment of Statin-Induced Necrotizing Autoimmune Myopathy With Glucocorticoid Monotherapy.

Statins are widely prescribed medications to prevent cardiovascular events such as myocardial infarction and stroke. Both myalgia and myopathy are well-known potential side effects of statins. However, a rare and severe form of statin-induced necrotizing autoimmune myopathy (SINAM) has recently been described and can lead to debilitating weakness, often requiring immunosuppressive therapy. We report a case of a 73-year-old male who made a complete recovery from SINAM following a three-month course of prednisone monotherapy.
