Why is this medication prescribed?
Sunitinib is used to treat gastrointestinal stromal tumors (GIST; a type of tumor that grows in the stomach, intestine (bowel), or esophagus (tube that connects the throat with the stomach) in people with tumors that were not treated successfully with imatinib (Gleevec) or people who cannot take imatinib. Sunitinib is also used to treat advanced renal cell carcinoma (RCC, a type of cancer that begins in the cells of the kidneys). Sunitinib is also used to help prevent the return of RCC in people who have RCC that has not spread and have had a kidney removed. Sunitinib is also used to treat pancreatic neuroendocrine tumors (pNET, a type of tumor that begins in certain cells of the pancreas) in people with tumors that have worsened and cannot be treated with surgery. Sunitinib 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 stop or slow the spread of cancer cells and may help shrink tumors.
How should this medicine be used?
Sunitinib comes as a capsule to take by mouth with or without food. For the treatment of gastrointestinal stromal tumors (GIST), or for the treatment renal cell carcinoma (RCC), sunitinib is usually taken once a day for 4 weeks (28 days) followed by a 2-week break before beginning the next dosing cycle and repeated every 6 weeks for as long as your doctor recommends. For the prevention of RCC, sunitinib is usually taken once a day for 4 weeks (28 days) followed by a 2-week break before beginning the next dosing cycle and repeating every 6 weeks for 9 cycles. For the treatment of pancreatic neuroendocrine tumors (pNET), sunitinib is usually taken once daily. Take sunitinib at around the same time every day.

What should I know about storage and disposal of this medication?
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. http://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. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA’s Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.
