Drug Interaction Report

Taking the nilotinib and magnesium oxide doses too close together may interfere with the absorption of nilotinib and reduce its effectiveness. To prevent or minimize the interaction, nilotinib and magnesium oxide dosing should be separated by at least two hours. Contact your doctor if your condition worsens. 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.

Do not consume grapefruit or grapefruit juice during treatment with nilotinib unless directed otherwise by your doctor. Grapefruit juice can increase the blood levels of nilotinib to dangerous levels, increasing the risk of an irregular heart rhythm that may be serious. You should seek immediate medical attention if you develop sudden dizziness, lightheadedness, fainting, shortness of breath, or heart palpitations during treatment with nilotinib. Food may also increase the blood levels of nilotinib. Therefore, you should take nilotinib on an empty stomach, meaning no food should be eaten for at least two hours before or one hour after taking nilotinib.
