What Arixtra is used for
Arixtra is used to prevent blood clots forming in patients who are recovering from orthopaedic or abdominal surgery. Arixtra is also used to treat blood clots once they have formed. Arixtra contains the medication fondaparinux sodium, a synthetic compound which helps prevent blood clots forming in blood vessels. This type of blood clot, also called deep venous thrombosis, or DVT, can occur in patients who are confined to bed after hip or knee surgery.
Your doctor may have prescribed Arixtra for another reason. Ask your doctor if you have any questions about why Arixtra has been prescribed for you.
Arixtra is not addictive.
This medicine is available only with a doctor's prescription.
