Severe hepatic cholestasis after treatment with amoxicillin/clavulanic acid

Amoxicillin/clavulanate is a commonly used antibiotic. Though relatively rare, amoxicillin/clavulanate carries the highest incidence of idiosyncratic drug-induced liver disease. This case report presents an 80-year-old woman treated for simple respiratory tract infection with amoxicillin/clavulanate who was subsequently hospitalized with malaise and icterus and a biochemical cholestatic pattern with high alkaline phosphatase and bilirubin. Diagnostically challenging, ultimately, liver biopsy revealed drug-induced liver injury with a fatal course after attempt of supportive, symptomatic treatment.
