Warfarin 的機制與維生素 K 拮抗有關。病人不需完全禁食綠色蔬菜，而是要保持維生素 K 攝取量「一致」，以利藥效穩定。完全禁食或突然大量攝取都會導致 INR 失控。阿斯匹靈具抗血小板作用，易增加出血風險。
Warfarin works by antagonizing vitamin K. The client does not need to eliminate green leafy vegetables but must keep vitamin K intake consistent to maintain stable drug effect. Complete avoidance or sudden large intake destabilizes INR. Aspirin has antiplatelet action and increases bleeding risk.
