Why is this medicine prescribed?
Tivozanib is used to treat advanced renal cell carcinoma (RCC; cancer that begins in the kidneys) that has returned or did not respond to at least two other medications. Tivozanib 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.
Are there other uses for this medicine?
This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
How should this medicine be used?
Tivozanib comes as a capsule to take by mouth. It is usually taken once daily with or without food for the first 21 days of a 28-day cycle. The cycle may be repeated as recommended by your doctor. Take tivozanib at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take tivozanib 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 open them.
Your doctor may decrease your dose or temporarily or permanently stop your treatment if you experience certain side effects. This depends on how well the medication works for you and the side effects you experience. Be sure to tell your doctor how you are feeling during your treatment with tivozanib.
What special precautions should I follow?
Before taking tivozanib,
- tell your doctor and pharmacist if you are allergic to tivozanib, aspirin, tartrazine (a yellow dye in some processed foods and drugs), any other medications, or any of the ingredients in tivozanib capsules. Ask your pharmacist for a list of the ingredients.
- tell your doctor and pharmacist what other prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking or plan to take. Be sure to mention any of the following: apalutamide (Erleada), carbamazepine (Carbatrol, Epitol, Equetro, Tegretol, Teril), enzalutamide (Xtandi), phenytoin (Dilantin, Phenytek), and rifampin (Rifadin, Rimactane, in Rifamate, in Rifater). Your doctor may need to change the doses of your medications or monitor you carefully for side effects.
- tell your doctor and pharmacist what herbal products you are taking, especially St. John's wort. Do not take St. John's wort while taking tivozanib.
- tell your doctor if you have an unhealed wound or if you have or have ever had a bleeding problem; a blood clot; heart failure; a heart attack; high blood pressure; seizures; or heart, thyroid, kidney or liver disease.
- tell your doctor if you are pregnant, plan to become pregnant, or if you plan to father a child. You or your partner should not become pregnant while you are taking tivozanib. If you are female, you will need to have a pregnancy test before you start treatment, and you should use birth control to prevent pregnancy during your tivozanib treatment and for 1 month after your final dose. If you are male, you and your partner should use birth control to prevent pregnancy during your treatment with tivozanib and for 1 month after your final dose. Talk to your doctor about birth control methods that you can use during your treatment. Tivozanib may decrease fertility in men and women. However, you should not assume that you or your partner cannot become pregnant. If you or your partner become pregnant while taking tivozanib, call your doctor. Tivozanib may harm the fetus.
- tell your doctor if you are breastfeeding. You should not breastfeed during your treatment with tivozanib and for 1 month after your final dose.
- you should know that tivozanib may cause high blood pressure. Your blood pressure should be checked regularly while you are taking tivozanib.
- if you are having surgery, including dental surgery, tell the doctor or dentist that you are taking tivozanib. Your doctor will probably tell you to stop taking tivozanib at least 24 days before your scheduled surgery because it can affect wound healing. Your doctor will tell you when to start taking tivozanib again after your surgery.

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.
What other information should I know?
Keep all appointments with your doctor and the laboratory. Your doctor will order certain lab tests to check your body's response to tivozanib.
Do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription.
It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
