Cancer Home > Precautions and Warnings With Ponatinib
Ponatinib may increase your risk for blood clots, liver damage, and other complications. To help minimize your risk for these and other problems, talk to your healthcare provider about your medical history before starting treatment with ponatinib. Other warnings and precautions with this chemotherapy drug apply to people taking certain medications and those who have certain allergies.
- Liver disease, such as hepatitis, cirrhosis, or liver failure
- Ever had a blood clot or stroke
- Heart problems of any kind
- High blood pressure (hypertension)
- Ever had pancreatitis
- An upcoming surgery
- Any allergies, including to foods, dyes, or preservatives.
Also, let your healthcare provider know if you are:
- A frequent alcohol drinker
- Pregnant or thinking of becoming pregnant
You should also tell your healthcare provider about all other medications you are taking, including prescription and nonprescription medicines, vitamins, and herbal supplements.
Some warnings and precautions to be aware of prior to taking this medication include the following:
- Ponatinib may increase the risk for blood clots in the arteries or veins. This can lead to heart attacks, strokes, or other serious complications. This very serious risk must be considered before you start treatment. As many as 27 percent of people taking this medication will develop a blood clot of some sort.
- This medicine can cause liver toxicity, including fatal liver failure. Your healthcare provider should monitor your liver function, using simple blood tests, starting before you begin treatment and continuing at least once a month.
- Up to 71 percent of people taking ponatinib develop high blood pressure (hypertension). Your healthcare provider should monitor your blood pressure during treatment.
- Ponatinib may increase the risk for pancreatitis (dangerous inflammation of the pancreas). In order to monitor for this problem, your healthcare provider should check your serum lipase, using a blood test, at least once every two weeks for the first two months, followed by monthly thereafter. People who have had pancreatitis in the past or who abuse alcohol may need even more frequent lipase testing.
- This medication may cause irregular heart rhythms (arrhythmias). Let your healthcare provider know immediately if you experience any signs of this problem, such as:
- Chest palpitations.
- This medication may cause low blood cell counts, including low platelets (thrombocytopenia), low red blood cells (anemia), and low white blood cells (neutropenia). A low platelet count increases the risk for dangerous bleeding, while a low white blood cell count increases the risk for infection. Your healthcare provider will monitor your blood counts with blood tests routinely during treatment. Let your healthcare provider know right away if you develop a fever, signs of infection, or unusual bleeding or bruising.
- Ponatinib can cause the body to retain fluid, which could lead to potentially serious problems, especially if the fluid builds up around the lining of the heart, lungs, or stomach. Let your healthcare provider know if you have signs of fluid retention (known as edema), such as:
- Unexplained weight gain
- Swelling in any area of your body
- Shortness of breath
- Chest pain.
- Based on the way it works, ponatinib could, at least theoretically, interfere with wound healing. Therefore, it is usually recommended to stop taking the drug for one week before major surgeries.
- Ponatinib may react with a number of other medications (see Drug Interactions With Ponatinib).
- Ponatinib is a pregnancy Category D medication, which means it may harm an unborn child. Talk to your healthcare provider about the risks and benefits of using this medication when pregnant (see Iclusig and Pregnancy).
- It is unknown whether ponatinib passes through breast milk. Therefore, if you are breastfeeding or plan to start, discuss this with your healthcare provider prior to taking the drug (see Iclusig and Breastfeeding).
