The dose that works.: There is no exact upper limit to Coumadin (warfarin) although the most I have seen someone need is about 12mg daily. Because Coumadin (warfarin) is so closely monitored with blood tests the right answer is the limit is the dose that gets you to your goal inr. Some people are genetically "coumadin resistant" and need much higher doses and people with high vitamin k diets also need higher doses.

Depends on why: You are taking it. Atrial fibrillation? Stroke. Artificial heart valve? Death. Deep venous thrombosis? Pulmonary embolus. Pulmonary embolus? Death. Not a good idea to stop it if your doctor put you on it, unless there is a serious bleeding complication, then it should be stopped under a doctor's supervision.

What are the risks of Coumadin (warfarin) levels of 3.1 is it a concern?

Not concerned.: Target range for INR is generally 2-3. 3.1 is barely out of range. It very slightly raises your risk of bleeding over your risk when you are at 3.0. Depending upon your doc this level may or may not produce a change in your dosing.
