Applies to: Nizoral (ketoconazole) and toremifene
Talk to your doctor before using toremifene together with ketoconazole. Combining these medications may significantly increase the blood levels of toremifene. This can make you more likely to develop side effects such as vaginal bleeding, blood clots, or an irregular heart rhythm that may be serious or life-threatening. You may not be able to take toremifene during treatment with ketoconazole, or you may need a dose adjustment and/or more frequent monitoring by your doctor to safely use both medications. Contact your doctor if you experience potential signs and symptoms of blood clots such as chest pain, shortness of breath, sudden loss of vision, and pain, redness or swelling your arms or legs. You should also seek immediate medical attention if you develop sudden dizziness, lightheadedness, fainting, or fast or pounding heartbeats during treatment with toremifene. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
Drug and food interactions
ketoconazole food
Applies to: Nizoral (ketoconazole)
You should avoid the use of alcohol while being treated with ketoconazole. Ketoconazole may cause liver damage and using it with alcohol or products containing alcohol may increase that risk. In addition, consumption of alcoholic beverages or products containing alcohol during treatment with ketoconazole may trigger a disulfiram-like reaction in some patients, with unpleasant symptoms such as flushing, palpitations, and nausea. Ketoconazole may be taken with or without food. You should avoid consumption of grapefruit, grapefruit juice, or any supplements that contain grapefruit extract during treatment with ketoconazole unless directed otherwise by your doctor. Grapefruit juice may increase the blood levels of ketoconazole. This may increase the risk and/or severity of side effects and liver problems. You should seek immediate medical attention if you develop signs and symptoms of liver damage during treatment with ketoconazole, such as joint pain or swelling, unusual bleeding or bruising, skin rash, itching, loss of appetite, fatigue, nausea, vomiting, dark colored urine, light colored stools, and yellowing of the skin or eyes. Talk to your doctor if you have any questions or concerns. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
