What is the most important information I should know about dasatinib?
Dasatinib is a cancer medication that slows the growth and spread of cancer cells in the body.
Dasatinib can lower blood cells that help your body fight infections and help your blood to clot. You may get an infection or bleed more easily. Call your doctor if you have unusual bruising or bleeding, or signs of infection (fever, chills, body aches).
Some people using dasatinib have developed a rare but serious condition called pulmonary arterial hypertension (PAH). PAH may be irreversible if not promptly treated, and this condition can be fatal. Talk to your doctor about your specific risk of developing PAH.
What should I discuss with my health care provider before taking dasatinib?
Some people using dasatinib have developed a rare but serious condition called pulmonary arterial hypertension (PAH). PAH occurs when blood pressure increases inside the arteries in your lungs. This makes it harder for your heart to pump blood through the lungs, which also weakens muscles in the heart. PAH may be irreversible if not promptly treated, and this condition can be fatal. Talk to your doctor about your specific risk of developing PAH.
To make sure dasatinib is safe for you, tell your doctor if you have:
low levels of potassium or magnesium in your blood;
anemia (lack of red blood cells);
heart disease or a heart rhythm disorder; or
a personal or family history of Long QT syndrome.
FDA pregnancy category D. Do not use dasatinib if you are pregnant. It could harm the unborn baby. Tell your doctor if you become pregnant during treatment.
Use birth control to prevent pregnancy while you are receiving dasatinib, whether you are a man or a woman. Dasatinib use by either parent may cause birth defects. A man taking dasatinib should use a condom during any sexual activity.
This medication may affect fertility (your ability to have children), whether you are a man or a woman.
