Fondaparinux: Frequently Asked Questions Answered

What is Fondaparinux?

Fondaparinux is a common blood thinner or anticoagulant. It helps treat deep vein thrombosis (DLT) by avoiding the formation of blood clots in the legs. Fondaparinux is also used to treat blood clots in the lungs. 

If the blood clots in the legs are not treated, they can travel to the heart, lungs, or brain, which may cause fatal issues like serious breathing problems, stroke, or a heart attack.

How does Fondaparinux work?

This drug is very similar to heparin, which works by blocking certain substances in the bloodstream that cause clotting.

It is also used to prevent blood clots after surgeries like hip fracture, knee, and hip replacement, which have a high risk of blood clot formation.

    Frequently Asked Questions about Fondaparinux

    Yes, it is. It acts by blocking substances in the blood that lead to the clotting reaction. Fondaparinux, thus, is a drug of choice to treat DVT in the legs as well as clots in the lungs. It is also used to prevent blood clotting after surgeries like hip replacement that cause severe bleeding.

    Fondaparinux should be stopped 36-42 hours before a surgery that carries a high risk for hemorrhage or spinal anesthesia procedure. This drug is more commonly used after surgery to prevent blood clots, and the doctor may advise taking it 6 to 8 hours after a knee/hip replacement surgery and continuing.

    Fondaparinux belongs to a class of medications called Factor Xa inhibitors that work by reducing the ability of blood to clot, which may cause strokes.

    Enoxaparin is used to prevent and treat blood clots. It helps blood flow smoothly through blood vessels by lowering the activity of clotting proteins in the bloodstream.

    Both Lovenox and Fondaparinux are used to prevent blood clots. Lovenox, though, is a specialized drug to prevent blood clots that cause the dangerous DVT.

    The way the two drugs act is vastly dissimilar too. Fondaparinux is a Factor Xa inhibitor. Enoxaparin works by inhibiting a blood protein called Thrombin, preventing clotting.

    No, Fondaparinux is not low molecular weight heparin (LMWHs), but Enoxaparin is. Fondaparinux is the first in a new breed of anticoagulants called Factor Xa inhibitors.

    Both LMWHs and Factor Xa inhibitors do similar work but have slightly different mechanisms of actions, profiles, and contraindications and FDA safety indications.

    Yes, Fondaparinux Sodium injections are not taken together with a few selected anticoagulants, thrombolytics, antiplatelets/Mifepristone, other heparins, NSAIDS, Salicylates and a host of other medicines.

    When taken together, these drugs may have serious interactions. Always consult your doctor before taking any medicine if you are on the anticoagulant Fondaparinux.

    Fondaparinux is given by injection under the skin of the stomach, usually once daily. Do take care that you don’t inject into a muscle.

    Follow the doctor’s advice regarding the dosage and length of treatment. Use this drug regularly and inject at the same time daily to get the most benefit from it.

    Follow the instructions of your doctor on how to store this medicine. Store Fondaparinux injection out of reach of children and pets. Don’t freeze it.

    Do not throw the unused injections in trash or flush the liquid down the toilet. Do only dispose of this medicine through a medicine take-back program.

    This is not recommended as the drug may be dangerous. There is a lack of sufficient safety data in humans but experts know enough about this drug to avoid medicating pregnant women. Do tell your doctor if you are pregnant, he will prescribe a less harmful blood thinner for you.

    Using Fondaparinux while breastfeeding is not recommended, because there is an absence of sufficient human data. Research in animals shows it is excreted into animal milk. According to some researchers, this medicine can be used if really needed and the benefits of its use far outweigh the risk.
