WHAT IT DOES

Enter a patient's current weekly warfarin dose and latest INR result. WarfarinWisely determines whether the INR falls within the therapeutic target range, calculates a guideline-based dose adjustment, and outputs a recommended new weekly dose alongside a practical daily dosing schedule.
