After two days of administration, the patient had become jaundiced and her urine was dark. She felt tired, anorexic and nauseated with mild epigastric pain. A liver scan four days after the episode indicated hepatocellular dysfunction. She denied any other factors which may have contributed to the episode.[Ref]
