A 66-year-old male patient developed jaundice after 7 months of treatment with the anabolic steroid, stanozolol. When the drug was withdrawn he made a full and uneventful recovery. A liver biopsy showed the histology of a hypersensitivity reaction. This is believed to be the first time jaundice has been recorded with stanozolol therapy and the first time a hypersensitivity-type jaundice has been recorded with any anabolic steroid.
