Uses For ponatinib
Ponatinib is used to treat chronic myeloid leukemia (CML) or Philadelphia chromosome positive acute lymphoblastic leukemia (Ph+ ALL) after other medicines did not work well. Leukemia is a type of cancer where the body makes abnormal white blood cells.
Ponatinib is an antineoplastic (cancer) medicine. It interferes with the growth of cancer cells, which are eventually destroyed by the body. Since the growth of normal cells may also be affected by ponatinib, other side effects can occur. Before you begin treatment, talk to your doctor about the benefits of ponatinib as well as the possible risks of using it.
ponatinib is available only with your doctor's prescription.
Before Using ponatinib
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For ponatinib, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to ponatinib or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Appropriate studies have not been performed on the relationship of age to the effects of ponatinib in the pediatric population. Safety and efficacy have not been established.
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of ponatinib in the elderly. However, elderly patients are more likely to have unwanted effects (eg, decreased appetite, extra fluid, muscle spasms, trouble breathing), which may require caution and an adjustment in the dose for patients receiving ponatinib.
Studies in women breastfeeding have demonstrated harmful infant effects. An alternative to this medication should be prescribed or you should stop breastfeeding while using ponatinib.

Precautions While Using ponatinib
It is very important that your doctor check your progress at regular visits to make sure that ponatinib is working properly. Blood tests may be needed to check for unwanted effects.
Using ponatinib while you are pregnant can harm your unborn baby. Use a highly effective form of birth control to keep from getting pregnant during treatment and for 3 weeks after your last dose of ponatinib. If you think you have become pregnant while using the medicine, tell your doctor right away.
ponatinib may cause blood clotting problems. Check with your doctor right away if you have chest pain, numbness or weakness in your arm, leg, or on one side of your body, trouble breathing, speech problems, or leg pain or swelling.
Check with your doctor right away if you have stomach pain, pale stools or dark urine, a loss of appetite, or yellow eyes or skin. These could be symptoms of a serious liver problem.
ponatinib may cause fluid retention and heart failure. Check with your doctor if you are rapidly gaining weight, have chest pain or discomfort, extreme tiredness or weakness, trouble breathing, or swelling of the hands, wrist, ankles, or feet. These may be symptoms of heart problems or too much water in your body.
Pancreatitis may occur with ponatinib. Tell your doctor right away if you have sudden and severe stomach pain, chills, constipation, nausea, vomiting, fever, or lightheadedness.
Check with your doctor immediately if you have vision changes, such as blurred vision, difficulty reading, or eye pain, dryness, irritation, or swelling, during treatment. Your doctor may want you to have your eyes checked by an eye doctor.
Check with your doctor right away if you are having decreased or increased sensitivity to pain or touch, or burning, numbness, tingling, or painful sensations in the arms, hands, legs, or feet. These could be symptoms of a nerve problem (eg, cranial or peripheral neuropathy).
Ponatinib can temporarily lower the number of white blood cells in your blood, increasing the chance of getting an infection. It can also lower the number of platelets, which are necessary for proper blood clotting. If this occurs, there are certain precautions you can take, especially when your blood count is low, to reduce the risk of infection or bleeding:
- If you can, avoid people with infections. Check with your doctor immediately if you think you are getting an infection or if you get a fever or chills, cough or hoarseness, lower back or side pain, or painful or difficult urination.
- Check with your doctor immediately if you notice any unusual bleeding or bruising, black, tarry stools, blood in the urine or stools, or pinpoint red spots on your skin.
- Be careful when using a regular toothbrush, dental floss, or toothpick. Your medical doctor, dentist, or nurse may recommend other ways to clean your teeth and gums. Check with your medical doctor before having any dental work done.
- Do not touch your eyes or the inside of your nose unless you have just washed your hands and have not touched anything else in the meantime.
- Be careful not to cut yourself when you are using sharp objects such as a safety razor or fingernail or toenail cutters.
- Avoid contact sports or other situations where bruising or injury could occur.
ponatinib may increase your chance of having blood clots or a brain condition called reversible posterior leukoencephalopathy syndrome (RPLS). Tell your doctor right away if you develop sudden and severe headaches, fainting spells, seizures, unusual drowsiness, confusion, or problems with vision, speech, or walking while you are using ponatinib.
ponatinib may cause a serious type of reaction called tumor lysis syndrome. Your doctor may give you a medicine to help prevent this. Call your doctor right away if you have a decrease or change in urine amount, joint pain, stiffness, or swelling, lower back, side, or stomach pain, a rapid weight gain, swelling of the feet or lower legs, or unusual tiredness or weakness.
ponatinib may affect the way your body heals from cuts and wounds. Make sure any doctor who treats you knows that you are using ponatinib. You might need to stop using ponatinib several weeks before having surgery. If you have questions about this, talk to your doctor.
If you plan to have children, talk with your doctor before using ponatinib. Some women using ponatinib have become infertile (unable to have children).
Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal (eg, St. John's wort) or vitamin supplements.
