What should be done for a patient on warfarin with an INR greater than 8 and no bleeding?

For a patient on warfarin with an INR greater than 8 and no bleeding, the appropriate management is to stop warfarin and administer 1-5 mg of oral Vitamin K. This recommendation aligns with established guidelines for such scenarios.

The rationale behind this approach is that an INR greater than 8 indicates a significantly increased risk of bleeding, even in the absence of active bleeding. By discontinuing warfarin, you remove the anticoagulant effect, and administering Vitamin K aids in reversing the anticoagulation effect of warfarin by promoting the synthesis of clotting factors that are dependent on Vitamin K. This method is effective for managing elevated INR levels without the associated risks of more invasive interventions.

Other options, like increasing the warfarin dosage, would further exacerbate the problem by raising INR levels even higher, which is contraindicated. Administering fresh frozen plasma is often reserved for cases where there is significant bleeding, as it provides immediate clotting factors but is not necessary when there is no bleeding and only an elevated INR. Starting immediate hemodialysis is not appropriate in this context; hemodialysis plays no role in the management of warfarin excess and would be a drastic and unnecessary measure. Thus,
