華法林(warfarin)是一種維生素 K 拮抗劑,透過抑制凝血因子合成來達到抗凝血效果。其治療窗窄,必須嚴格監測國際標準化比值(INR)。服用抗凝血劑的病人若出現黑色柏油樣便(tarry stools,即黑便),代表上消化道有潛在出血(GI bleeding),這是危及生命的警訊,必須立即介入處理。
Warfarin is an anticoagulant with a narrow therapeutic window that increases the risk of bleeding. Tarry stools indicate gastrointestinal hemorrhage, a serious adverse effect that requires immediate reporting and intervention to prevent life-threatening complications.
