Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Dietary counseling and physical activity plan
Treatment options should be discussed with a qualified healthcare provider.
Low-dose aspirin therapy
Antiplatelet therapy to reduce thrombotic risk by inhibiting platelet aggregation, typically used as first-line pharmacologic intervention for symptomatic patients.
Therapeutic phlebotomy
Regular blood removal to reduce hematocrit levels and blood viscosity, decreasing thrombosis risk particularly in patients with marked erythrocytosis.
Additional treatment options
Cytoreductive therapy
Hydroxyurea or other agents to reduce platelet production in high-risk patients or those failing aspirin/phlebotomy, lowering thrombotic complications.
medicationCardiovascular risk reduction
Smoking cessation, regular exercise, maintaining healthy weight, and managing hypertension/diabetes to minimize thrombotic risk factors.
lifestyleRegular hematologic monitoring
Frequent complete blood count monitoring to track platelet trends, assess treatment response, and detect progression toward secondary myelofibrosis or acute leukemia.
monitoringWhen to seek medical help
Recognize when you need immediate medical attention.
