[Toxic hepatitis caused by ketoconazole: a report of 4 cases]

The authors describe four cases of toxic hepatitis due to ketoconazole. All patients were female and were given the drug from 8 to 16 weeks (200mg/day). The clinical condition of the four patients was similar to that of viral hepatitis. Normalization of clinical and laboratory findings occurred 60 to 90 days after discontinuation of the drug and no patient died. One patient received ketoconazole again after her clinical and laboratory results were normalized, and a new toxic hepatitis appeared within 15 days; the second discontinuation of the drug lead to cure of the hepatitis.
