The target INR range can vary depending on the individual's condition and the indication for anticoagulation. Generally, a target INR of 2.0 to 3.0 is recommended for most indications, but it may be higher (2.5 to 3.5) in patients with mechanical heart valves or other high-risk conditions. It is vital to keep the INR within the recommended range to balance the risk of bleeding against the risk of clotting.
