Comparison of Oral vs Intravenous Phytonadione ( Vitamin K 1 ) in Patients With Excessive Anticoagulation

Background: Treatment of patients with excessive anticoagulation is routinely done by intravenous phytonadione (vitamin K1). Oral administration of phytonadione has been shown to be an effective alternative to the intravenous route, but these methods have never been compared directly. Our objective was to compare efficacy and safety of intravenous vs oral phytonadione treatment in patients with excessive anticoagulation without bleeding.
