Nilotinib is used to treat a type of blood cancer called Philadelphia chromosome positive chronic myeloid leukemia (CML) in adults and children who are at least 1 year old. Nilotinib is usually taken every 12 hours on an empty stomach.
Nilotinib can cause a serious heart problem, especially if you use certain other medicines at the same time. Nilotinib is usually given after other treatments have failed.
