Read the information carefully and ask your doctor or pharmacist if you have any questions.

WHY is this medicine prescribed?
Nilotinib is used to treat certain types of chronic myeloid leukemia (CML; a type of cancer of the white blood cells), including treatment in people whose disease could not be treated successfully with imatinib (Gleevec) or people who cannot take imatinib. Nilotinib is in a class of medications called kinase inhibitors. It works by blocking the action of the abnormal protein that signals cancer cells to multiply. This helps to stop or slow the spread of cancer cells.
HOW should this medicine be used?
Nilotinib comes as a capsule to take by mouth. It is usually taken without food twice a day. Nilotinib should be taken on an empty stomach, at least 1 hour before or 2 hours after eating any food. Take nilotinib at around the same times every day. Try to space your doses about 12 hours apart. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take nilotinib exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Swallow the capsules whole with a glass of water; do not split, chew, or crush them. If you are not able to swallow the capsules whole, mix the contents of a capsule in one teaspoon of applesauce. Swallow the mixture immediately (within 15 minutes.) Do not store the mixture for future use.
Your doctor may decrease your dose of nilotinib during your treatment. This will depend on how well the medication works for you and any side effects you may experience. Continue to take nilotinib even if you feel well. Do not stop taking nilotinib without talking to your doctor.
