Drug-induced liver injury caused by the histrelin (Vantus) subcutaneous implant

Drug-induced liver injury (DILI) is the leading cause of acute hepatic failure in the United States. Up to 13% of acute liver failure cases occur due to drugs other than acetaminophen. This clinical diagnosis, made after other causes of liver injury have been excluded, requires establishing a causal relationship between drug exposure and liver injury. The case of a patient with liver injury following a subcutaneous histrelin (Vantus) implant as therapy for advanced prostate cancer is presented.
