[Hepatic encephalopathy induced by flutamide administered for the treatment of prostatic cancer].

Abstract

A 72-year-old male treated with flutamide for metastatic prostate cancer developed lethargy and confusion. He was noted to be icteric and his liver enzymes were elevated. Within a week of discontinuing the medication, the patient's mental status and liver function returned to normal. Although flutamide-induced near fatal liver dysfunction has been described, progression to encephalopathy is a rare occurrence. Based on a review of the literature, management guidelines for the use of flutamide are suggested.
