polycythemia vera
"Been taking Jakafi for 9 months .... 10mg 2x daily. Just now counts slightly increasing so my Dr is adding another 5mg daily to my dose. This med has improved my life significantly .... my over functioning has improved 100% but still with some issues.

It's scary to change medications, I hope my comment will give others courage and hope ... if their Dr thinks it's worth giving it a try."
