Precautions
Drug information provided by: Merative, Micromedex®
It is very important that your doctor check your progress at regular visits to make sure this medicine is working properly. Blood tests will be needed to check for unwanted effects. Be sure to keep all appointments.
Fondaparinux may cause bleeding problems. This risk is higher if you have a catheter in your back for pain medicine or anesthesia (sometimes called an "epidural"), or if you have kidney problems. The risk of bleeding increases if your kidney problems get worse. Check with your doctor right away if you have any unusual bleeding or bruising, black, tarry stools, bleeding gums, blood in the urine or stools, tingling, numbness, or weakness of the lower legs, or pinpoint red spots on your skin.
You may bleed or bruise more easily while you are using this medicine. Stay away from rough sports or other situations where you could be bruised, cut, or injured. Be careful when using sharp objects, including razors and fingernail clippers. Avoid nose picking and forceful nose blowing.
Be careful when using a regular toothbrush, dental floss, or toothpick. Your medical doctor, dentist, or nurse may recommend other ways to clean your teeth and gums. Check with your medical doctor before having any dental work done.
Make sure any doctor or dentist who treats you knows that you are using this medicine. You may need to stop using fondaparinux several days before having surgery or medical tests.
Also, tell your doctor if you have received fondaparinux or heparin before and had a reaction called thrombocytopenia (low platelet count in the blood), or if new blood clots formed while you were receiving the medicine.
This medicine may increase your risk of having spinal or epidural blood clots when it is used together with certain other medicines or procedures. Check with your doctor right away if you have midline back pain, numbness, tingling, or weakness in the legs or feet, or loss of control of the bowel or bladder (incontinence).
The needle guard of the prefilled syringe of this medicine contains dry natural latex rubber. Tell your doctor if you have any allergies with latex or rubber.
Check with your doctor before you start or stop taking any other medicine, or change the amount you are taking. This includes prescription or nonprescription (over-the-counter [OTC]) medicines, and herbal or vitamin supplements. Many medicines change the way this medicine affects your body.
