Prolonged cholestasis and progressive hepatic fibrosis following imipramine therapy

Abstract This report describes a middle-aged female who received imipramine for 7 days, developed severe cholestatic jaundice with features similar to primary biliary cirrhosis, and then improved clinically over the next 12 mo. Biochemical and histologic abnormalities persisted over a 14-yr period of follow-up, though subsequent administration of haloperidol may have influenced the long-term course. High levels of circulating immune complexes were also found 14 yr later, which raises questions about the relationship of primary biliary cirrhosis to drug-induced liver injury. A review of the literature on imipramine- and phenothiazine-related hepatic injuries reveals multiple similarities, and this case provides further evidence for a common hepatic reaction to the two drugs.
