2

Folic Acid Supplementation

Daily folic acid supplementation to support increased erythropoiesis in patients with chronic hemolysis. This helps compensate for increased RBC turnover and prevents folate deficiency complications.

dietary
3

Hematologic Monitoring

Regular monitoring of hemoglobin levels, reticulocyte count, and bilirubin to assess hemolysis activity and transfusion needs. Includes periodic ultrasound evaluation for hepatosplenomegaly.

monitoring

Additional treatment options

Oxidative Stress Avoidance

Use of antioxidants and avoidance of oxidative stressors including certain antibiotics (sulfonamides), antimalarials, and foods like fava beans that can trigger hemolytic episodes.

medication

Blood Transfusion Support

Transfusion therapy for severe symptomatic anemia, typically reserved for crisis situations or when hemoglobin drops significantly below baseline.

medication

Splenomegaly Management

Avoidance of contact sports and activities that increase splenic injury risk when hepatosplenomegaly is present. Physical activity modifications based on anemia severity.
