Ketoconazole can cause serious (possibly fatal) side effects and drug interactions. 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 nausea/vomiting that doesn't stop, 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. Ketoconazole must not be used with certain other medications because a serious, possibly fatal, drug interaction may occur. Ketoconazole interacts with drugs such as 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 rarely cause 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.

See also Warning and How to Use sections. Ketoconazole interacts with many prescription and nonprescription drugs. While you are taking ketoconazole, it is very important to tell your doctor or pharmacist of any changes in medications that you are taking. Some products that may interact with this drug include: other drugs that can cause liver problems (such as acetaminophen). Other medications can affect the removal of ketoconazole from your body, which may affect how ketoconazole works. Examples include isoniazid, nevirapine, rifamycins (such as rifabutin, rifampin), St. John's wort, among others. This medication can slow down the removal of many other medications from your body, which may affect how they work. Examples of affected drugs include some benzodiazepines (such as alprazolam, midazolam, triazolam), domperidone, eletriptan, eplerenone, ergot drugs (such as ergotamine), nisoldipine, drugs used to treat erectile dysfunction-ED or pulmonary hypertension (such as sildenafil, tadalafil), some drugs used to treat seizures (such as phenytoin), some statin drugs (such as lovastatin, simvastatin), among others. Ketoconazole requires acid in the stomach to be well absorbed. If you are taking drugs that decrease the amount of stomach acid including antacids, heartburn/ulcer drugs (H2 blockers such as cimetidine, famotidine, ranitidine), sucralfate, or if you are taking drugs that slow down gut movement (anticholinergics such as dicyclomine, propantheline), take ketoconazole at least 2 hours before any of these drugs. If you are taking proton pump inhibitors (PPIs such as lansoprazole, omeprazole), ask your doctor or pharmacist for advice on how to reduce or avoid this interaction. Ketoconazole is very similar to levoketoconazole. Do not use medications containing levoketoconazole while using ketoconazole.
