I was diagnosed with Polycythaemia a year ago. I was initially treated with Asprin, followed by venesection . Three months ago I started Hydroxycarbamide 500 mg daily and Allopurinol 300mg. I had four venesections in total, before the consultant stopped them and increased the dose of Hydroxy to 1000mg mon,wed,fri, and 500mg the remaining days. In the last fortnight it has been increased to 1000mg x 4days and 300mgx 3days.
My blood pressure was monitored before and after each venesection and prior to having monthly blood tests where it was always within normal limits. During my latest visit to my GP surgery It was found to be high and when checked at the Haematology clinic a week ago it remains high . My consultant does not feel this is related to the meds which he has prescribed, yet there has been no other changes to other medication which I take .
I do note that, although not very common, Allopurinol has been found to cause high blood pressure, 1 in 10,000 cases.
I just wondered if anyone else has experienced this sudden onset Hypertension.
