Atorvastatin-Induced Liver Injury With Concurrent Rhabdomyolysis After a Positive Rechallenge

Statin-induced liver injury has been widely described. However, cases of clinically significant liver injury are rare. We present a 56-year-old woman who developed atorvastatin-induced grade III acute liver injury with concurrent rhabdomyolysis that worsened after rechallenging, which highlighted the need for pharmacovigilance with statins. The Roussel Uclaf Causality Assessment Method and Revised Electronic Causality Assessment Method both showed that atorvastatin was highly probable in causing hepatotoxicity. To our knowledge, this is the first reported case of concurrent drug-induced liver injury and rhabdomyolysis after a positive rechallenge with atorvastatin.
