Vitamin k may let blood thinner users skip Pre-Surgery drug holiday

This small pilot study tests whether giving a one-time dose of vitamin K before surgery can safely lower the blood-thinning effect of warfarin, so patients can keep taking their regular medication without interruption. The study will enroll 20 adults who have been on warfarin for at least 3 months and use home INR testing. The main goals are to see if this approach is practical and how well it works to bring INR levels down to a safe range for surgery.
