FLUCLOXACILLIN INDUCED DELAYED CHOLESTATIC HEPATITIS

We report four cases of severe delayed cholestatic hepatitis induced by flucloxacillin. All patients presented with deep jaundice and pruritus which developed soon after ceasing flucloxacillin. Liver function tests were abnormal in all patients with markedly elevated serum bilirubin concentration, alkaline phosphatase and aspartate transaminase levels. Extrahepatic biliary obstruction and infective hepatitis were excluded in all cases. Liver biopsies showed centrilobular cholestasis with portal and lobular inflammation and eosinophil infiltration. Although symptoms resolved within six weeks in all patients, cholestatic liver function tests have persisted in two patients for more than six months. With the increasing usage of this drug and the delayed presentation of cholestasis, flucloxacillin needs to be considered in the differential diagnosis of all patients presenting with cholestatic jaundice.
