This drug causes dose-related myopathy which, in rare cases maybe severe and sometimes take the form of rhabdomyolysis with or without renal failure secondary to myoglobinuria; rarely fatalities have occurred. The incidence of myopathy with the 80 mg dose has been reported as disproportionately higher than that observed at lower doses and the risk of myopathy with simvastatin 80 mg/day is greater compared with other statins with similar or greater LDL-C lowering efficacy.[Ref]

With therapy discontinuation or interruption, transaminase levels generally returned to pretreatment levels. There have been rare postmarketing reports of hepatic failure.[Ref]
