The use of fresh frozen plasma or vitamin K is considered an effective way to reverse elevated INR levels caused by warfarin. Warfarin is an anticoagulant that works by inhibiting vitamin K-dependent clotting factors in the liver. When INR levels are too high, which indicates a greater risk of bleeding, administering vitamin K can help restore the production of those clotting factors and bring the INR back into a safer range.

Fresh frozen plasma is another option because it contains all the clotting factors. By administering it, you essentially provide the necessary components to aid in blood coagulation, thereby effectively countering the effects of warfarin.

In contrast, simply stopping the dosage of warfarin may reduce INR levels over time, but this method does not provide immediate correction for an already elevated INR. While it can lead to a gradual decrease in INR, it may not be sufficient in emergency situations where rapid reversal is necessary. Calcium supplements and blood transfusions do not address the specific issue of elevated INR and the need for restoring clotting factor levels affected by warfarin.
