Not related: The INR is not used to come off the warfarin. Inr is a measure of the blood clotting ability and is used to monitor the effect of the warfarin. The goal is between 2 and 3. If less than 2, the warfarin effect is not enough to protect one and > 3 it causes excess bleeding risk. The duration of therapy depends on circumstances surrounding the DVT and can range from 3 months to lifetime treatment.

Time not level: As dr. Depietro said, keeping your INR beteen 2 and 3 while you take Coumadin (warfarin) is important but how long you stay on Coumadin (warfarin) depends on a number of factors that aren't determined by your inr.
