WARNING: Ketoconazole can cause serious (possibly fatal) side effects and drug interactions. Therefore, it should only be used when other treatments have not worked, are not available, or cannot be taken by you. Discuss the risks and benefits of this medication, as well as other effective and possibly safer treatments for fungal infections, with your doctor.

Ketoconazole has rarely caused very serious (possibly fatal) liver problems. Get medical help right away if you develop symptoms of liver problems, including persistent nausea/vomiting, stomach/abdominal pain, dark urine, yellowing eyes/skin, loss of appetite, or light colored stools. To reduce your risk for liver problems, your doctor should obtain liver function tests every week while you are taking this medication. Do not drink alcoholic beverages while taking ketoconazole because alcohol increases the risk of serious liver problems. See also Notes section.

Ketoconazole must not be used with certain other medications because a serious, possibly fatal, drug interaction may occur. Ketoconazole interacts with drugs such as cisapride, disopyramide, dofetilide, dronedarone, methadone, pimozide, quinidine, ranolazine, among others. These interactions may increase the risk of a certain condition that affects the heart rhythm (QT prolongation). QT prolongation can infrequently result in serious (rarely fatal) fast/irregular heartbeat and other symptoms (such as severe dizziness, fainting) that need medical attention right away. Tell your doctor and pharmacist about all the medications and products you may be taking before you start ketoconazole treatment. See also Precautions section.
