I have been on Hydroxyurea for PV for 3 years or so, and have now developed marked breathlessness which is beginning to get problematic. I am having cardiac investigation 24-hr holter), but just read Maz's response from some months ago about side-effects on the lungs from Hydrea: sounds like me! What kind of tests are needed for this condition to be diagnosed? I know my haematologist will want me to stay on Hydrea as it is controlling my blood counts well, but quality of life is definitely deteriorating.
