Fosfomycin-Induced Liver Injury: A Case Report.

Fosfomycin is an antibiotic frequently used to treat uncomplicated urinary tract infections. It is normally well-tolerated, but there are some reports of clinically relevant liver injury. We present the case of a 73-year-old female who presented with paucisymptomatic hepatocellular acute liver injury six days after taking fosfomycin. After ruling out viral, ischemic, and autoimmune hepatitis, as well as Wilson disease and biliary disorders, she was diagnosed with drug-induced liver injury (DILI) related to fosfomycin. The patient showed major improvement during the first week and the resolution of liver injury one month after onset. This case report aims to underscore the potential hepatotoxicity of fosfomycin.
