What is the INR value indicating maintenance of coagulation while on Coumadin?

The correct INR value indicating the maintenance of coagulation while on Coumadin (warfarin) is typically between 2.0 and 3.0 for most conditions requiring anticoagulation. However, for certain conditions, such as the treatment of mechanical heart valves or specific thromboembolic disorders, a slightly higher range of 2.5 to 3.5 may be indicated to ensure adequate therapeutic effects while minimizing the risk of clot formation. Coumadin's anticoagulant effect is closely monitored with INR testing, and the target range may vary depending on the patient's specific clinical scenario, but for those needing higher anticoagulation intensity, maintaining an INR within the 2.5 to 3.5 range is often necessary to effectively prevent thrombosis while balancing the risk of bleeding.
