About therapeutic phlebotomy▼

Therapeutic phlebotomy is the primary treatment for polycythemia vera. It reduces blood volume and hematocrit, improving circulation and reducing clot risk. The goal is to maintain HCT below 45%.

Expect a temporary dip in energy and recovery scores immediately after a draw — this is normal and typically resolves within 5–10 days as your body regenerates red blood cells.

Frequency depends on your HCT response. Some patients need draws every 4–8 weeks initially; once HCT is stable below 45%, the interval often lengthens to every few months.
