Warfarin 是一種維生素 K 拮抗劑（Vitamin K Antagonist），其藥效極易受飲食中維生素 K 攝取量影響。護理衛教的重點是「維持攝取穩定」，因為攝取量忽高忽低會導致國際標準化比值（INR）波動。此外，由於藥物會抑制凝血因子，病人需採取出血預防措施，並嚴禁在未經醫師同意下服用 NSAIDs 或阿斯匹靈，以免加重出血風險。
Warfarin is a vitamin K antagonist, and its effect is highly influenced by dietary vitamin K intake. The key point in nursing education is to maintain a consistent intake, because fluctuating intake leads to fluctuations in the International Normalized Ratio (INR). In addition, because the medication suppresses clotting factors, the client must take bleeding precautions, and the use of NSAIDs or aspirin is strictly prohibited without the physician's approval in order to avoid an increased risk of bleeding.
