What should I know about ketoconazole before taking it?

Ketoconazole may interact with some dietary supplements or prescription drugs, such as rifabutin, other antifungals, seizure medicines, protease inhibitors, nefazodone, delavirdine, erythromycin, methadone, disopyramide, dronedarone, ranolazine or fluconazole. Tell your doctor if you have a personal or family history of long QT syndrome, liver disease, kidney disease, any heart rhythm disorder or decreased stomach acid (achlorhydria). Because of the risk of liver damage or dangerous interactions with other drugs, oral ketoconazole should never be the first-choice treatment for a fungal infection.
