Blood Home > Arixtra
Available by prescription, Arixtra is a drug licensed to treat and prevent blood clots. This medication comes in the form of an injection and is administered just under the skin once daily. It works by slowing down clot formation, allowing the body to break down the clots naturally. Potential side effects may include bleeding and skin reactions.
What Is Arixtra?Arixtra® (fondaparinux sodium) is a prescription medication approved to prevent and treat blood clots. It is taken by injection just below the skin.
How Does Arixtra Work?Arixtra works by inhibiting a specific clotting factor known as factor Xa (pronounced "ten A"). It is more selective than heparin (including both unfractionated heparin and low molecular weight heparins), which inhibits other clotting factors as well. Notably, this medication does not affect blood platelets. It is not a heparin medication.
