After a pulmonary embolism how long do i need to take coumadin (warfarin)?

See your doctor: May need 6 months. If you have abnormal clotting factors in your blood, you may need it longer.

It depends: We always treat patients with DVT and pulmonary embolus for a minimum of 6 months and usually 12. Work-up for hypercoagulability (predisposition for abnormal blood clotting) is always performed, usually after the year of Coumadin (warfarin) treatment. If you have a hypercoagulable state as determined by blood testing, you may need anti coagulation for life.
