Arixtra contains a synthetic substance called fondaparinux sodium. This stops a clotting factor Xa (“tenA”) from working in the blood, and so prevents unwanted blood clots (thromboses) from forming in the blood vessels.
Arixtra is used to:
- prevent the formation of blood clots in the blood vessels of the legs or lungs after orthopaedic surgery (such as hip or knee surgery) or abdominal surgery
- prevent the formation of blood clots during and shortly after a period of restricted mobility due to acute illness.
- treat some types of heart attack and severe angina (pain caused by narrowing of the arteries in the heart).
- treat blood clots in blood vessels that are near the surface of the skin of the legs (superficial vein thrombosis).
Always use this medicine exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure.
The recommended dose is 2.5 mg once a day, injected at about the same time each day.
If you have kidney disease, the dose may be reduced to 1.5 mg once a day.
