Which treatment is primarily used for managing symptoms in polycythemia vera?

Phlebotomy is primarily used in the management of polycythemia vera because this condition is characterized by an excessive production of red blood cells, which can lead to increased blood viscosity and a higher risk of thrombotic events. By performing phlebotomy, blood is removed from the body, thereby reducing the concentration of red blood cells and improving blood flow. This treatment helps alleviate symptoms such as headaches, dizziness, and hypertension that are commonly associated with the elevated hematocrit seen in patients with polycythemia vera.

Other treatment options like chemotherapy and radiation therapy are generally not first-line interventions for symptom management in this condition. While bone marrow transplant may be considered in some severe cases or when other treatments are ineffective, it is not a primary approach for managing symptoms of polycythemia vera. Phlebotomy remains the most direct and effective method to manage the heightened blood cell levels and associated complications in these patients.
