Rhabdomyolysis, if related to this drug alone, should have been observed much earlier. This indicates that co-administration is likely respon- sible for this toxicity. Rhabdomyolysis has been reported after co-administration of simvastatin and levofloxacin in a patient with normal renal function. 9 Our patient had received simvastatin along with levofloxacin a year earlier when she also suffered acute renal impairment from con- trast nephropathy; despite this, rhabdomyolysis was not observed. The mechanism underlying rhabdomyolysis due to co-administration of these drugs remains unclear. This may be due to intrinsic myotoxicity of levofloxacin or due to inhibition of P-gp mediated drug efflux. Co- administration of these drugs should be discour- aged especially in elderly patients with renal im- pairment. Muscle injury markers are still above normal at four months; however, muscle weak- ness shows improvement. This improvement, along with creatinine kinase level being less than 10 times normal, argues against statin- associated autoimmune myopathy. 11 References 1. Chou R, Dana T, Blazina I et al.
