Foods that are high in vitamin K can affect the way warfarin works in your body. Vitamin K helps your blood clot and works against warfarin. The more vitamin K-rich foods you eat, the lower the levels of warfarin in your body. This means your INR will be lower, and you will be more likely to form a blood clot.
Herein, what do you do if INR is too high?
The PT is reported as the International Normalized Ratio (INR). If the INR is too low, blood clots will not be prevented, but if the INR is too high, there is an increased risk of bleeding. This is why those who take warfarin must have their blood tested so frequently.
How do you treat high INR?
Before vitamin K is administered, the potential for warfarin resistance must be balanced against the risk of bleeding — determined according to the patient's indication for anticoagulation. The treatment options for patients who have been over-anticoagulated are: Dose omission. Oral phytomenadione (vitamin K1)
What does it mean to have a high INR level?
If your PT/INR test result is too high, it means that your blood is clotting too slowly, and you are at risk of bleeding. Your dose of warfarin is too high. On the other hand, if your PT/INR test result is too low, your dose of warfarin may not be enough to protect your blood from clotting.
