had DVT (pulmonary Thromboembolism) 4 years ago and have been on Warfarin since then two years ago I have been diagnosed with Polycythemia Vera and after many phlebotomies I was put on Hydroxy urea. Is there any one out there with both these ailments ?? The reason for this query is if I manage my PT-INR, my hemocrit levels go overboard; on the other hand, if I manage my hemocrit levels, my PT-INR goes for a six!!
