We report a case of rhabdomyolysis and acute compartment syndrome of the lower extremity in a schizophrenic patient taking risperidone following the addition of simvastatin to treat hyperlipidemia. We suspect that disrupted drug metabolism, resulting from interactions with cytochrome P450 enzymes, rapidly elevated drug plasma levels, which then led to muscle toxicity. Clinicians who pharmacologically treat medical comorbidities in patients receiving atypical antipsychotics must be proactive in anticipating potential drug-drug interactions.
