What is the initial dose of coumadin in a patient with newly diagnosed venous thromboembolism (VTE)?

By William Aird

Suggested initial dosing is 5-10 mg (warfarin) orally to target INR 2-3. VKA is initiated with parenteral anticoagulation for ≥ 5 days and until INR is ≥ 2 for at least 24 hours, at which point parenteral anticoagulation can be discontinued. Learn more here.
