Ponatinib has caused serious (sometimes fatal) blood clots (such as heart attack, stroke, pulmonary embolus-PE, deep vein thrombosis-DVT). Get medical help right away if you develop symptoms of a blood clot, including chest/jaw/left arm pain, confusion, slurred speech, weakness on one side of the body, severe headache, severe dizziness, sudden vision changes, trouble breathing, pain/swelling/redness of arms/legs.
Ponatinib can also rarely cause very serious (possibly fatal) liver disease. Your doctor will order blood tests to check your liver before you start and while you are taking ponatinib. Tell your doctor immediately if you develop symptoms of liver disease, including persistent nausea, stomach/abdominal pain, dark urine, yellowing eyes/skin. Your doctor may need to change your dosage or discontinue the drug.
Ponatinib is used to treat certain types of blood cancer (chronic myelogenous leukemia-CML, acute lymphoblastic leukemia-ALL). It works by slowing or stopping the growth of cancer cells. It belongs to a class of drugs known as kinase inhibitors.
The U.S. Food and Drug Administration (FDA) has asked the manufacturer to stop marketing and selling ponatinib because of the risk of serious blood clots (see Warning section). If you are responding to ponatinib treatment and your doctor feels this outweighs the risks of using ponatinib, then your doctor can get permission from the FDA to continue treatment with ponatinib. It is important to talk to your doctor about the risks of treatment with ponatinib.
