Polycythemia Vera Resource Guide

At a Glance

Polycythemia Vera (PV) is a highly manageable, chronic blood cancer that causes the body to overproduce red blood cells. By maintaining a hematocrit level below 45% through treatments like phlebotomy and medication, patients can effectively control symptoms and minimize the risk of blood clots.

Receiving a diagnosis of Polycythemia Vera (PV) can feel overwhelming. The term “blood cancer” is frightening, but PV is a highly manageable, chronic condition. By understanding your diagnosis and partnering with the right care team, you can take control of your health and protect your future.

This guide is designed to empower you with the facts. It breaks down the biology of the disease, explains how to read your lab reports, and prepares you for conversations with your specialist.

Common questions in this guide

Is Polycythemia Vera a type of cancer?
Yes, Polycythemia Vera is classified as a blood cancer, specifically a myeloproliferative neoplasm (MPN). However, it is a highly manageable, chronic condition that can be controlled with routine monitoring and treatment.
What is the target hematocrit level for Polycythemia Vera?
The standard of care for Polycythemia Vera aims to keep your hematocrit level strictly below 45 percent. Maintaining this level is critical because it significantly reduces your risk of blood clots and cardiovascular complications.
What are the common symptoms of Polycythemia Vera?
Hallmark symptoms of Polycythemia Vera include profound fatigue, brain fog, and intense itching, which is especially common after a hot shower or contact with water. Managing your blood counts can help alleviate many of these symptoms.
What treatments are used for Polycythemia Vera?
Treatment typically includes a daily low-dose aspirin and therapeutic phlebotomy to physically remove excess blood. Depending on your risk level for blood clots, doctors may also prescribe cytoreductive medications like Hydroxyurea, Interferon, or Jakafi to lower your blood counts.

Questions to Ask Your Doctor

Curated prompts to bring to your next appointment.

  1. 1.What is my current hematocrit level, and what target are we aiming for?
  2. 2.Am I considered 'low risk' or 'high risk' for blood clots, and how does that affect my treatment plan?
  3. 3.Do you specialize in myeloproliferative neoplasms (MPNs), and how many patients with PV do you treat?
