Gonzalezz3. Lovonox, a blood thinner, used with abdominal surgery is indicated in patients at higher risk for deep vein thrombosis, which is blood clots in the legs. Severe problems can arise if the clot breaks off and goes to the lungs. Many practices, including ours, includes the medicine as part of the surgical cost, because of its importance. It costs us around $10 per syringe, but we buy in bulk. You may be able to buy it cheaper on line or at Walmart pharmacies. There is also an increased risk for blood clots when flying, so be sure to move around and walk frequently on your trip home from Miami, and don't fly too soon after surgery. Best of luck!
