Before using dasatinib, tell your doctor if you have liver disease, low levels of potassium or magnesium in your blood, heart disease or a heart rhythm disorder, or if you have a personal or family history of "Long QT syndrome."

There are many other medicines that can interact with dasatinib. Tell your doctor about all the prescription and over-the-counter medications you use.

Dasatinib can lower the blood cells that help your body fight infections. This can make it easier for you to bleed from an injury or get sick from being around others who are ill. To be sure your blood cells do not get too low, your blood will need to be tested on a regular basis. It is important that you not miss any scheduled visits to your doctor.

Avoid contact with people who have colds, the flu, or other contagious illnesses. Contact your doctor immediately if you develop signs of infection.
