Summary
Ponatinib is used to treat certain types of leukemia, which is a cancer of the blood and bone marrow. It is specifically effective for chronic myeloid leukemia and Philadelphia chromosome-positive acute lymphoblastic leukemia, helping to control the disease and improve symptoms like fatigue and fever.
Ponatinib works by blocking specific proteins called tyrosine kinases, which promote cancer cell growth. By inhibiting these proteins, it helps stop the growth and spread of cancer cells, making it effective for treating certain types of leukemia.
The usual starting dose of Ponatinib for adults is 45 mg once daily. It is taken orally, with or without food. The dose may be adjusted by a doctor based on response and side effects. It's important to follow the doctor's specific dosing instructions.
Common side effects of Ponatinib include fatigue, which is feeling very tired, headaches, and stomach upset like nausea or diarrhea. These effects vary from person to person and should be discussed with a doctor if they become severe or persistent.
Ponatinib can increase the risk of blood clots, which can lead to heart attack or stroke. It may also cause liver problems and high blood pressure. It should not be used by individuals with a history of blood clots or severe liver issues.
