This drug can infrequently 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.
To decrease the risk of this effect, 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. Therefore, 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 is used to treat a certain type of blood cancer (chronic myelogenous leukemia-CML). It works by slowing or stopping the growth of cancer cells.
