This medication has caused very serious blood clots (such as heart attack, stroke, pulmonary embolus-PE, deep vein thrombosis-DVT). You may be at increased risk for blood clots if you have a history of blood clots, heart/blood vessel disease, liver disease, or if you are immobile (such as being bedridden after surgery). Talk with your doctor about the risks and benefits of this medication. Get medical help right away if you develop symptoms of a blood clot, such as pain/swelling/redness/weakness of the arms or legs, calf pain/swelling that is warm to the touch, shortness of breath, coughing up blood, chest/jaw/left arm pain, sudden vision changes, weakness on one side of the body, trouble speaking, or confusion.
This medication is used to treat and prevent bleeding in people with certain conditions (such as hemophilia type A or B, low levels of factor VII, Glanzmann's thrombasthenia). People with these conditions are at risk for bleeding longer after an injury/surgery and for bleeding inside the body (especially into the joints and muscles). This product contains a man-made form of factor VIIa, which is a protein (clotting factor) in the blood that works with other clotting factors to help the blood clot and stop bleeding.
