What is the desired INR range for a patient on Coumadin?

For a patient on Coumadin (warfarin), the desired International Normalized Ratio (INR) range is typically between 2.0 and 3.0, particularly for the management of conditions such as atrial fibrillation, venous thromboembolism, or to prevent stroke. This range is crucial because it indicates an appropriate level of anticoagulation that effectively reduces the risk of thromboembolic events while minimizing the potential for bleeding complications.

An INR below this range could indicate insufficient anticoagulation, leading to an increased risk of clot formation, while an INR above this range suggests excessive anticoagulation, raising the risk of bleeding. Therefore, monitoring and managing a patient's INR within the established therapeutic range is essential for ensuring safe and effective treatment with Coumadin.
