Myopathy secondary to simvastatin in a type 2 diabetic patient.

The most important but rare adverse effect of simvastatin is myopathy. In megatrials with simvastatin, the overall incidence of myopathy is 0.025%. We present a case of myopathy presenting as proximal muscle weakness in both upper limbs secondary to simvastatin which reversed spontaneously after cessation of the drug.
