Deep vein thrombosis with blood clot in leg vein in pregnancy. how long do i need to take medicine for it?

6 months : Dvt in pregnancy is treated with a variation of Heparin called Lovenox which is injected just under the skin twice a day. Coumadin (warfarin) is fatal to the fetus and should never be given during pregnancy. A 3 to 6 month recommendation is given depending on the patient's other ongoing risk factors after delivery.

Until after delivery: I completely agree with dr. Vorhies. Pregnancy increases the risk for getting a blood clot in the leg and the risk increases the further you are into the pregnancy. That risk doesn't return to normal until 6 weeks after delivery. Sometimes there are other risks for getting a blood clot in addition to being pregnant. How long you stay on blood thinners, depends on what other risks you have.

3 months: I would recommend that you are treated for a minimum of 3 months post pregnancy with anti-coagulation. You should also wear your compression stockings for 2 to 3 years. This can decrease your risk of developing post thrombotic syndrome which is when the valves in the deep veins do not work and you have chronic swelling and pain.
