fondaparinux SubQ Warnings
Tell your doctor you use/have used fondaparinux before having any procedures involving puncture of the spine or needles left in the spine to give pain-blocking medication (including lumbar punctures, indwelling spinal/epidural catheters). Also, before starting fondaparinux, tell your doctor if you have had any of these procedures. Using this medication before/after these procedures has rarely caused severe bruising/bleeding in the area of the spine (epidural/spinal hematoma). This effect may cause paralysis that may be permanent. Discuss the risks and benefits of treatment with your doctor. Tell your doctor immediately if you have any of these serious side effects: back pain, tingling, weakness, numbness, or difficulty urinating. (See also Precautions section.)
This risk is increased the longer the needles are left in the spine or the more often these spinal puncture procedures are done. Using other "blood-thinning" or anti-platelet medications such as aspirin, clopidogrel, or warfarin, or nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen or naproxen, also increases the risk. Do not stop taking any prescribed medication without first consulting your doctor. Your doctor will monitor you closely while you are using this medication.
fondaparinux SubQ Uses
Fondaparinux is used to treat serious blood clots in the legs and/or lungs. It is usually used with another "blood thinner" medication (warfarin). If untreated, blood clots can travel to the lungs, heart, or brain, causing serious (possibly fatal) breathing problems, heart attack, or stroke. This drug may also be used to prevent blood clots after certain surgeries with an increased risk of blood clots (e.g., hip fracture, abdominal, knee/hip replacement).
Fondaparinux is known as a "blood thinner" (anticoagulant). It is a drug similar to heparin that works by blocking certain natural substances in the blood that cause clotting.How to use fondaparinux SubQ
This medicine comes with a Patient Information Leaflet. Read it carefully. Learn all preparation and usage instructions in the product package. Ask your doctor, nurse, or pharmacist any questions that you may have about this medicine.
Before injecting each dose, clean the injection site with rubbing alcohol. It is important to change the location of the injection site daily to avoid problem areas under the skin.
Before using, check this product visually for particles or discoloration. If either is present, do not use the liquid. Do not mix any other medication in the same injection.
Inject this medication under the skin of the stomach/abdomen, usually once daily or as directed by your doctor. Do not inject into a muscle. To lower the risk of bruising, do not rub the injection site after a shot.
When treating a blood clot, another "blood thinner" (warfarin) is usually started within 3 days after you start using fondaparinux. Your doctor will direct you to use both of these medications until the warfarin is working well. Do not stop either of these medications until your doctor directs you to stop.
To prevent blood clots due to surgery, your doctor may direct you to start using this medication (usually 6 to 8 hours after surgery) and continue for several days. Follow your doctor's directions closely. Starting this medication too soon after surgery may increase the risk of serious bleeding.
Use this medication regularly to get the most benefit from it. To help you remember, use it at the same time each day. Dosage and length of treatment are based on your medical condition and response to treatment. Dosage may also be based on your weight.
