Acute hepatitis induced by bupropion.

As an antidepressant, bupropion is considered to be a safe agent that usually causes infrequent and mild increase of serum liver enzymes. Asymptomatic elevation of serum transaminases was previously reported only in a single case. We describe a patient who developed typical acute hepatitis after receiving six weeks of bupropion for depression. His presentation was characterized with acute onset of symptoms associated with significantly elevated ALT, AST, and LDH and acute hepatic inflammation. The clinical course of our patient, including incubation period, pattern of liver enzyme elevation, and time of recovery, was similar to, but much more severe than, the case reported by Oslin and Duffy. Discontinuation of bupropion was followed by a rapid resolution of clinical symptoms and liver enzymes. The incidence of bupropion-induced hepatitis remains to be defined even though it appears to be relatively low. Since the clinical application of bupropion is broader, we must be aware of the clinical entity of bupropion-induced hepatitis.
