I am 58 and was diagnosed with ET 5 years ago after a routine blood test my count os presently approx 700. But for the diagnosis i feel well though have cardiovascular disease and take asprin,  statins and blood pressure meds. I run 5k twice per week, go the gym and am generally very active. I was asked by my consultant to take Hydrauxeria. But i read about the side affects and chose not to as i felt fine. My Consultant sees me reguarly to check my count, my condition and to see if i will change my mind. She says that at this moment she will not make me take it. But she says that once I'm 60 she will be less tolerant and will insist. Is anyone else not taking the medocation, and what is the prognosis for someone who doesn't take it, dedpite how active they are?
