A patient with hyperlipidemia who had a gallbladder stone caused by administration of fenofibrate.

Fibrates are widely used for treatment of hyperlipidemia. It has been reported that gallbladder stones are formed by administration of clofibrate. It is thought that fenofibrate can cause the formation of gallbladder stone as a side effect. We encountered a patient with hyperlipidemia in whom a gallbladder stone was detected by computed tomographic scanning 3 months after the start of administration of fenofibrate during follow-up observation by blood biochemical examination and computed tomographic scanning. This case report will be of great value and importance.
