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.

Talk to your doctor about the risks of taking nilotinib.

Nilotinib is used to treat certain types of chronic myeloid leukemia (CML; a type of cancer of the white blood cells) who have recently found to have this condition in adults and children 1 year of age and older. It is also used to treat certain types of CML in adults whose disease could not be treated successfully with imatinib (Gleevec) or adults who cannot take imatinib because of side effects. Nilotinib is also used to treat certain types of CML in children 1 year of age or older whose disease could not be treated successfully with other tyrosine kinase inhibitor therapies or who cannot take these medications because of side effects. 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.

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 2 hours before or 1 hour 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 nilotinib dose or stop your treatment depending on how well the medication works for you and if you experience any side effects. Continue to take nilotinib even if you feel well. Do not stop taking nilotinib without talking to your doctor.

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location — one that is up and away and out of their sight and reach. https://www.upandaway.org

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet.
