Presumed interaction of fusidic acid with simvastatin.

A 63-year-old man was admitted 6 weeks after an elective abdominal aortic aneurysm repair following which methicillin resistant Staphylococcus aureus (MRSA) had been cultured from the aneurysmal sac. He had been commenced on a course of fusidic acid at discharge in addition to his ongoing statin prescription and presented 4 weeks later with symptoms consistent with rhabdomyolysis. Severe rhabdomyolysis was confirmed and despite prolonged and complicated critical care management, his treatment was unsuccessful.
