    • What is this medication and its most common uses?

      Heparin sodium injection is a blood thinner used to treat and reduce the risk of developing a blood clot in the legs, lungs, and arteries. It is also used to prevent blood clots in people undergoing certain types of surgeries. In addition, heparin sodium injection is used to treat atrial fibrillation (an irregular, fast heartbeat) in people who have an obstruction in their blood vessel. Additionally, it is used to treat disseminated intravascular coagulation (a bleeding and clotting disorder). Heparin sodium injection is also used to prevent the formation of clots during blood transfusions and dialysis. Heparin sodium injection is administered intravenously (through a vein in your arm) or subcutaneously (just below the skin).

      What: By lowering the chance of blood clots forming in your body, heparin sodium injection may reduce your risk of having a stroke, heart attack, or other serious conditions.

    • What are the possible side effects of this medication?
