I have had PV for almost eight years, and have had only half a dozen phlebotomies--necessary only when my hematocrit is 45% or above. The process is nothing to be afraid of, like donating a pint of blood if you've ever done that. It usually takes up to an hour, because a certain amount of normal saline is run through afterwards to clear the vein.

Not having any more phlebotomies is generally a good thing. Whenever your Dr. orders a procedure, changes your dosage, etc., they should explain to you what they are doing, and why. I write down what they tell me and then keep a notebook at home, because every once in awhile something gets missed. It is important for us to understand the what and why’s, look at our own labs and other test results, and to ask questions about anything we don’t understand. All the best to you,

That's a really important question to bring up with your hematologist, but here's some helpful context to guide that conversation.

Hydroxycarbamide (also known as Hydroxyurea) is a cytoreductive medication that slows down how many blood cells your bone marrow produces. It's typically recommended for people in the high-risk PV group — those aged 60 or older, or those with a history of blood clots. Even when taking Hydroxycarbamide, phlebotomy often remains part of the treatment plan. The two approaches can work together because:

- Phlebotomy directly reduces the number of excess red blood cells
- It helps keep hematocrit levels below 45%, which is the key target
- Hydroxycarbamide helps slow production, but may not always control hematocrit on its own The right combination really depends on your current blood counts, how well your hematocrit is being controlled, and how you're tolerating your current treatment. Your hematologist is best placed to assess whether phlebotomy should be added or continued alongside your Hydroxycarbamide.

It's worth asking at your next appointment: *"Is my hematocrit well-controlled enough, or should phlebotomy be part of my plan?"*

I ttook Hydroxurea for about 15 years and need phlebotomies frequently in the last 5 of those. After a few rounds of Ojjaara and Jakafi, I am off those and back on a daily dose of Hydroxurea. Just had a phlebotomy a couple of weeks ago. HCT was at 49.5. When it gets about 43 for me I get uncontrolled HBP and other issues so I know when it is time. No other control for PV/ While on Jakafi I didn't need any but I get anemic on it.
