Nilotinib sometimes causes side effects due to the rapid destruction of cancer cells (tumor lysis syndrome). To lower your risk, your doctor may add a medication and tell you to drink plenty of fluids. Tell your doctor right away if you have symptoms such as: low back/side pain (flank pain), signs of kidney problems (such as painful urination, change in the amount of urine), muscle spasms/weakness.

This drug can rarely cause serious (possibly fatal) irregular heartbeats (QT prolongation). Nilotinib should not be used in people with low blood levels of certain minerals (potassium, magnesium) or a certain heart problem (long QT syndrome). To lower your risk, your doctor will order certain blood tests (potassium/magnesium levels, liver function tests) before and during treatment with nilotinib. You should have a heart test (EKG) before starting nilotinib. The EKG should be repeated 7 days after your first dose, when your dose is changed, and periodically while you are taking nilotinib.

Nilotinib may come in different forms (such as tablet, capsule). Do not switch between different forms without consulting your doctor.

If you are taking the capsule form of this medication, do not eat for 2 hours before or 1 hour after taking your dose. Other drugs/foods may increase the risk of an irregular heartbeat. Before taking this drug, tell your doctor or pharmacist of all the products you use. Keep a list of all your medications with you, and share the list with your doctor and pharmacist. See also How to Use and Drug Interactions sections.

Nilotinib may cause a 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.

The risk of QT prolongation may be increased if you have certain medical conditions or are taking other drugs that may cause QT prolongation. Before using nilotinib, tell your doctor or pharmacist of all the drugs you take and if you have any of the following conditions: certain heart problems (heart failure, slow heartbeat, QT prolongation in the EKG), family history of certain heart problems (QT prolongation in the EKG, sudden cardiac death).

Low levels of potassium or magnesium in the blood may also increase your risk of QT prolongation. This risk may increase if you use certain drugs (such as diuretics/"water pills") or if you have conditions such as severe sweating, diarrhea, or vomiting. Talk to your doctor about using nilotinib safely.

Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).
