What INR range is considered therapeutic for patients taking anticoagulants like Coumadin?

For patients taking anticoagulants like Coumadin (warfarin), the therapeutic International Normalized Ratio (INR) range is typically 2.0 to 3.0. This range is important because it indicates an effective level of anticoagulation that helps prevent blood clots while minimizing the risk of excessive bleeding.

The INR is a standardized measure that allows healthcare providers to monitor the coagulation status of patients on warfarin. An INR lower than 2.0 could indicate insufficient anticoagulation, leading to the risk of thrombosis, while an INR significantly above 3.0 may increase the risk of bleeding complications.

Thus, the correct range that reflects therapeutic use in this scenario is 2.5 to 3.0.
