Warfarin is a commonly used oral anticoagulant for the prevention and treatment of various thromboembolic diseases. Usually only a few milligrams are enough to achieve the therapeutic purpose. The therapeutic window of warfarin is relatively narrow, so it can't play an anticoagulant role (ineffective) when the dose is small, and it will increase the risk of bleeding when the dose is large. Hemorrhage is the most common and dangerous side effect of warfarin, which can be life-threatening in severe cases.
Extended data:
Warfarin will be affected by some foods and drugs. As for diet, the general principle is to try to keep a stable eating habit. You don't have to deliberately avoid eating, and you don't have to deliberately not eat or eat less green vegetables, so you can maintain a normal daily consumption. Some foods can increase or decrease the effect of warfarin, so we should pay attention to it when taking medicine.
Foods that increase the anticoagulant effect of warfarin: alcohol, grapefruit juice, garlic, ginger, fennel, mango juice and pineapple.
Foods that reduce the anticoagulant effect of warfarin: soybean milk, some foods rich in vitamin K, such as broccoli, celery, cabbage, rapeseed oil, cucumber, cucumber skin (excluding peeled cucumber), kiwi fruit, lettuce leaves, mint leaves, green mustard, olive oil, pistachios, spinach leaves, soybeans, soybean oil and tea.
