title: Hepatotoxicity after short-term trazodone therapy.
abstract: OBJECTIVE
  To report a case of severe hepatotoxicity from a four-day course of trazodone in a patient being treated according to protocol in a detoxification center.
  
  
  METHODS
  A 46-year-old HIV-positive man with a past medical history of intravenous drug abuse and hepatitis C, who was well controlled with HIV medications, was admitted for cocaine withdrawal. The patient was started on a standard protocol at the detoxification center with methadone 50 mg/d, clonidine 0.1 mg twice daily for four days, and trazodone 200 mg/d for four days. Laboratory results showed acute hepatitis and cholestasis five days following admission. Trazodone and clonidine were discontinued at that time. His methadone and HIV regimens remained unchanged. Liver function test results were greatly improved 10 days after trazodone and clonidine discontinuation.
  
  
  CONCLUSIONS
  This is the first case report of trazodone-induced liver damage after only a few days of therapy. Previous reports describe hepatitis developing after weeks to months of trazodone therapy. All comorbidities thought to affect the described laboratory abnormalities were ruled out as a cause by a hepatologist. The observation of the sudden rise and fall of liver enzymes is characteristic of a drug reaction in the absence of trauma and severe shock.
  
  
  CONCLUSIONS
  Due to the temporal relationship of the introduction and withdrawal of trazodone in the medication regimen and the elevations in liver enzymes, we conclude that this patient experienced acute hepatitis induced by trazodone 200 mg/d therapy for four days. The findings of this case warrant caution and closer monitoring in a patient with multiple risk factors for liver damage.
