What Is A Generic?×
A generic drug is essentially a copycat version of a brand-name medication, offering the same safety, quality, and effectiveness, but often at a lower cost. When a brand-name drug's patent expires, other companies can produce the generic version. These generics contain the same active ingredients and work in the same way in the body as the original brand-name drug. However, they might differ in color, shape, or inactive ingredients. The appeal of generic drugs lies in their affordability; they provide a more cost-effective option for consumers without sacrificing the benefits of the original medication. This makes healthcare more accessible to a larger portion of the population, ensuring that more people can receive the treatment they need without the burden of high costs associated with brand-name drugs.
Arixtra, also known as fondaparinux, is an anticoagulant drug that inhibits Factor X blood clotting. Anticoagulants prevent blood clotting and are often known as blood thinners. Arixtra is administered as a subcutaneous injection.
It may be given to treat blood clots in patients where clots are already present. It’s also prescribed before surgical procedures that are associated with high blood clot risks. These procedures include abdominal surgeries, knee and hip replacements, and hip fracture repair. Doctors also use Arixtra treat angina (heart pain) and heart attacks.
Arixtra is delivered by subcutaneous injection, which means it is injected under the skin. Most often Arixtra is injected in the skin over the stomach or abdomen. Other injection sites may also be appropriate, but Arixtra should not be injected into a muscle.
Fondaparinux is typically prescribed for daily use. Patients may inject themselves with the medication or a caregiver or medical professional can administer the drug. In some cases, the first dose of Arixtra is delivered via IV.

How does Arixtra Work?
Arixtra’s mechanism of action inhibits Factor X blood clotting. Clotting Factor X is an enzyme that initiates the formation of a blood clot in the arteries, veins, and heart. Clotting is typically a healthy response to the injury of a blood vessel. However, blood clots can pose dangerous risks if they become loose and move about the body. Mobile clots can cause breathing problems, heart attacks, and stroke. Fondaparinux prevents the Factor X enzyme from beginning the clotting process. This prevents clot formation which reduces the risk of stroke, heart attack, and breathing problems.
Arixtra is often administered alongside other anticoagulants or blood thinners.
Precautions and Warnings of Arixtra
Arixtra impacts a patient’s blood and circulatory system, which can have wide-ranging effects throughout the body. Since Arixtra reduces blood clotting, it interferes with the body’s normal response to injuries and wounds. Patients must immediately inform their medical team if they are injured or involved in an accident. Avoid contact sports and using sharp items like razors while on this medication.
Do not use fondaparinux if you are allergic to it. Inform your doctor or pharmacist of all your allergies. The packaging and prefilled syringe include non-active ingredients that may contain allergens such as latex.

- Antiplatelet medications
- Other blood thinners including warfarin or coumadin
- Nonsteroidal anti-inflammatory drugs (NSAIDs)
Arixtra can be dangerous for patients with certain previous and existing medical conditions. Tell your doctor or pharmacist if you have any history of the following:
- Bacterial endocarditis (heart infection)
- Current bleeding such as a bleeding ulcer
- Low platelet count
- Blood-clotting conditions
- Eye problems caused by diabetes
- High blood pressure
- Kidney issues
- Stomach or other digestive problems
- Recent spinal procedures
- Spinal deformity
- Recent surgery
- Low body weight
