Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Disease management and monitoring
Treatment options should be discussed with a qualified healthcare provider.
Iron supplementation
Replacement therapy for iron deficiency anemia secondary to chronic blood loss from mucocutaneous telangiectasias.
Laser ablation therapy
Pulsed dye laser or similar modalities to ablate visible telangiectasias, reducing bleeding episodes and improving cosmetic appearance.
Additional treatment options
Antifibrinolytic agents
Tranexamic acid or similar drugs to reduce bleeding tendency by stabilizing fibrin clots in telangiectasia-affected tissues.
medicationRegular hemoglobin and iron studies
Scheduled blood work to monitor for anemia progression and guide iron replacement therapy timing and dosing.
monitoringBleeding precautions
Avoidance of NSAIDs, antiplatelet agents, and trauma risk; use soft-bristled toothbrush and gentle nasal care.
