Clofibrate-Induced Muscle Damage with Myoglobinuria and Cardiomyopathy

Abstract
To the Editor: A clofibrate-induced "acute muscular syndrome" has been reported in patients treated for hyperlipidemia with or without chronic renal failure.1 2 3 4 In 1970 a 16-year-old boy treated for diabetes insipidus with vasopressin as a nose spray was re-evaluated because of polyuria, fever and eosinophilia of the blood (count of 35 per cent) and bone marrow.

Because earlier treatment with chlorpropamide caused severe hypoglycemia, clofibrate in a dose of 4 X 500 mg daily was . . .
