Fulminant liver failure secondary to submassive hepatic necrosis in a patient treated with Orlistat. A case report.

Orlistat is an intestinal lipase inhibitor drug that is recommended in obese patients along with a hypocaloric diet. Although the most frequent secondary effect is steatorrhea, fulminant liver failure has also been associated with this drug, which has required liver transplantation in 3 patients. We present the case of a 42-year-old obese male.
