I have excessive thrombocytosis and have been taking anagrelide for over eight years now, and I have been told by my regular doctor that I have many symptoms of leukemia. I will see my oncologist soon who put me on this drug. I have a high white blood cell count, enlarged spleen, night sweats, and pain in the lower left side area and my upper left back. I am worried that this drug has caused leukemia. Can anyone give me some answers?
