Fulminant Chemical Hepatitis Possibly Associated with Donepezil and Sertraline Therapy

OBJECTIVE: To describe a case of fulminant hepatitis possibly related to concomitant donepezil and seratriline therapy. PATIENT AND SETTING: An 83‐year‐old woman treated in a dementia care facility and later in a tertiary medical center. INTERVENTION AND MANAGEMENT: Discontinuation of donepezil and sertraline therapy with subsequent improvement evidenced by liver biopsy and liver function tests. RESULTS: An older woman with Alzheimer's disease was admitted to a dementia care facility because of aggressive behavior. Treatment with sertraline was initiated in February 1998. Sertraline doses were increased gradually to 200 mg daily by May 1998, and some improvement in behavior was seen. Concomitant therapy with donepezil 5 mg qhs was initiated June 26, 1998. Ten days later, confusion and jaundice were noted. Total bilirubin was 5.6 mg/dL, GGTP was 1208 IU/L, and alkaline phosphatase was 369 IU/L. Computed tomography revealed cholelithiasis without ductal dilation. Liver, spleen, and pancreas seemed normal. Donepezil and sertraline were discontinued. The patient was admitted to our institution and treated for dehydration. A liver biopsy revealed scattered portal eosinophils and prominent cholestasis consistent with acute chemical hepatitis. The GGTP and total bilirubin of this patient peaked at 2235 IU/L and 22.6 mg/dL, respectively. The patient improved, and her liver function tests normalized over the next 2 months.
