| Summary: | Abstract Background Bupropion is an antidepressant that is also used as a non-nicotine method to aid in smoking cessation. Bupropion-induced hepatotoxicity is quoted to affect between 0.1% and 1% of treated patients with either a hepatocellular and/or cholestatic pattern of damage. The mechanism of damage is considered to be predominantly immune-mediated with the presence of a hypersensitivity syndrome (fever, rash, eosinophilia, autoantibodies) and a short latency period (1–6 weeks). We believe our reporting of this case to the already existing small list of only seven cases in the world literature will help practicing physicians to deal with the diagnostic and management dilemmas that bupropion-induced hepatotoxicity brings. Case presentation A 50-year-old Caucasian woman presented to our hospital with significant derangement of liver transaminases after 6 days of bupropion treatment for smoking cessation. The patient’s other medications were considered unlikely to be the cause of the hepatotoxicity and were therefore continued. The patient’s liver function tests normalized on withdrawal of bupropion, confirming that bupropion was the probable cause of the patient’s hepatotoxicity. Conclusions We conclude that hepatotoxicity is a rare adverse effect of bupropion use, but physicians should be aware of the possibility of this potentially serious clinical picture of drug-induced hepatotoxicity with varied clinical presentation and prognosis.
