Primary Polycythemia
Condition
(Polycythemia Vera [PCV]; Polycythemia Rubra Vera [PRV]; Erythremia)
Definition
Polycythemia is a condition of the bone marrow. It makes too many red blood cells and platelets. Sometimes, white blood cells are affected. The increase of blood cells can make the blood thicken and clot.
Early treatment lowers the risk of serious problems.

Causes
This condition is caused by changes to a gene. It is not clear what causes this to happen.
Risk Factors
Polycythemia is more common in men and people 40 years of age and higher. The risk is higher in people of Ashkenazi Jewish decent.
Symptoms
Some people with polycythemia have no symptoms. Others may have symptoms such as:
- Night sweats or hot flashes
- Reddish skin color
- Burning feeling in feet and hands
- Weight loss
- Bone pain or headaches
- Dizziness, tiredness, or weakness
- Problems with breathing, vision, or thinking
- Ringing in the ears—tinnitus
Blood clots increase the risk of a heart attack or stroke.
Diagnosis
Polycythemia is sometimes found during a routine blood test. The doctor will ask about symptoms and past health. A physical exam will be done.
Tests may include:
- Blood tests
- Genetic tests
- Abdominal ultrasound or CT scan—to see if the spleen is enlarged
- Bone marrow biopsy—to look for other problems or make the diagnosis
Treatment
Treatment depends on how severe the disease is. The goal is to manage the disease and problems linked to it—such as blood clots. For some, a mix of treatments works best.
Options may be:
- Medicines such as:
- Low-dose aspirin—to reduce the risk of blood clots
- Chemotherapy—to lower blood cell production, control blood thickness, and improve the immune system.
- JAK inhibitors—to reduce spleen size and improve the balance of other blood cells
- Ropeginterferon alfa-2b—to boost the immune system
- Blood taken from the veins at times—to lower the amount of red blood cells
- Surgery to remove the spleen—if it is causing problems
Prevention
There are no guidelines prevent polycythemia.
