IMPORTANT WARNING:
Nilotinib may cause QT prolongation (an irregular heart rhythm that can lead to fainting, loss of consciousness, seizures, or sudden death). Tell your doctor if you or anyone in your family has or has ever had long QT syndrome (an inherited condition in which a person is more likely to have QT prolongation) or you have or have ever had low levels of potassium or magnesium in your blood, an irregular heartbeat, or liver disease. Tell your doctor and pharmacist if you are taking amiodarone (Nexterone, Pacerone); antifungals such as ketoconazole, itraconazole (Sporanox, Tolsura), or voriconazole (Vfend); chloroquine (Plaquenil); clarithromycin; disopyramide (Norpace); erythromycin (E.E.S., Eryc, PCE); certain medications for human immunodeficiency virus (HIV) or acquired immunodeficiency syndrome (AIDS) such as indinavir (Crixivan), nelfinavir (Viracept), ritonavir (Norvir, in Kaletra), and saquinavir (Invirase); haloperidol (Haldol); methadone (Dolophine, Methadose); moxifloxacin; nefazodone; pimozide (Orap); procainamide; quinidine (in Nuedexta); sotalol (Betapace, Betapace AF, others); and thioridazine. If you experience any of the following symptoms, stop taking nilotinib and call your doctor immediately: fast, pounding, or irregular heartbeat; fainting; loss of consciousness; or seizures.
Do not eat any food for at least 2 hours before taking nilotinib and for 1 hour after taking this medication.
Keep all appointments with your doctor and the laboratory. Your doctor will order certain tests, such as blood tests and electrocardiograms (EKGs, tests that record the electrical activity of the heart) before and during your treatment to be sure that it is safe for you to take nilotinib.
Your doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when you begin treatment with nilotinib and each time you refill your prescription. Read the information carefully and ask your doctor or pharmacist if you have any questions. You can also visit the Food and Drug Administration (FDA) website (http://www.fda.gov/Drugs/DrugSafety/ucm085729.htm) or the manufacturer's website to obtain the Medication Guide.
Talk to your doctor about the risks of taking nilotinib.
