Polycythemia and hydrea
I wasn’t able to tolerate hydrea myself. Two attempts to use it and both times I became unable to exert myself, even small stairs left me breathless. Other non tolerance symptoms as well. Also, I too had heart racing and discomfort all around.
I am now on JAKAFI (Ruxolitnib). The JAKAFI is working well, but it too has side effects that are treatable. JAKAFI made my diastolic blood pressure rise, which is a potential side effect, and I am now taking 20 mg of Lisinopril daily and my blood pressure has returned to normal.
