I have had PV for ten years and am a 66 year old male. Phlebotomies & aspirin worked well for that time. Aquagenic priurits (itchiness on contact with water) had become unbearable by June 2022.
I went onto 500mg per day HU (Hydroxyurea).The itchiness started to decrease and now after 6 months has almost gone away.
I have come to the conclusion , for my body at least, that the White Blood Cell account (which had increased to around 18.0 (4.5-11 normal range) was the main driver of this painful side effect. I could not shower for 9 months.
WBC counts continue to drop to a more normal level.
I mention this as HU gets a lot of complaints on this site. For me it nothing short of a miracle. I feel fantastic.Do not dismiss this classic and effective treatment before trying it out.
