Is that your daily dosage? I was wondering how often you need phlebotomies? I’m taking 500mg 5 days on 2 off because 7 days a week, along with phlebotomy, lowered my platelets too much. I was just diagnosed about 11 weeks ago and I’m thinking it takes a while to get on some sort of schedule/routine? I was lucky not to ever have the itching. Headaches and tingling were my two PV symptoms.
