Drug-induced myopathy has been reported with use of lovastatin, nicotinic acid, and clofibrate. A particularly severe form, often accompanied by rhabdomyolysis, has been reported with the use of lovastatin and gemfibrozil; however, as far as we know, no case has been documented with use of gemfibrozil alone. Herein, we report the first case (to our knowledge) of gemfibrozil-induced myopathy, confirmed by drug rechallenge.
