Hepatotoxicity Serious hepatic toxicity caused by ketoconazole treatment is rare (1/15000). Acute hepatocellular injury has been primarily observed as has cholestatic injury or a mixed pattern of toxicity. Fatal cases have been reported particularly when treatment is continued despite liver enzyme elevation. Increases in liver enzymes (≤ 5N and > 5N) were observed in ~13.5 % and ~2.5% of patients respectively occurring mostly within the first 6 months of treatment. Liver enzyme levels returned to normal within 2-12 weeks after a dose decrease or withdrawal of ketoconazole. Hepatotoxicity does not appear to be dose dependent. All potential associated factors of hepatotoxicity, and abnormal liver enzyme levels detected before ketoconazole initiation, should be taken into account before considering ketoconazole treatment. Ketoconazole should not be administered when liver enzymes are greater than 2 times the upper limit of normal or in association with other hepatotoxic medicinal products. Liver enzyme monitoring should be performed once weekly during the first month of treatment and then monthly for 6 months. In the case an increase of liver enzymes is detected which is less than 3 times the upper limit of normal, closer monitoring of liver function should be performed and the daily dose should be decreased by at least 200 mg. In the case of increase of liver enzymes levels above 3 times the upper limit of normal, Ketoconazole should be stopped immediately and should not be reintroduced because of the risk of serious hepatic toxicity.
