How do you reverse vitamin K?
Rapid reversal required (within 24 hours; e.g. for surgery) • Hold warfarin. Give Vitamin K 2 mg -4 mg orally (INR should be reduced within 24 hours). If INR remains high, give an additional dose of Vitamin K 1 mg -2 mg orally. Restart warfarin at lower dose once INR is within therapeutic range.
