OverviewAcute liver failure is loss of liver function that occurs quickly — in days or weeks — usually in a person who has no preexisting liver disease. It's most commonly caused by a hepatitis virus or drugs, such as acetaminophen. Acute liver failure is less common than chronic liver failure, which develops more slowly. Show
Acute liver failure, also known as fulminant hepatic failure, can cause serious complications, including bleeding and increased pressure in the brain.
