Tell your doctor you use Arixtra before you have any type of spinal puncture or epidural/spinal anesthesia. Patients who have these procedures while they use Arixtra are at risk of developing a blood clot on or near the spinal cord. This could result in long-term or permanent paralysis.
The risk is increased in patients who have an indwelling epidural catheter, traumatic or repeated epidural or spinal puncture, a history of a deformed spine or spinal surgery, and in patients who use medicines that may affect blood clotting, such as warfarin, aspirin, platelet inhibitors (eg, clopidogrel), and nonsteroidal anti-inflammatory drugs (NSAIDs) (eg, ibuprofen, naproxen).
If you have a spinal puncture or epidural/spinal anesthesia while you use Arixtra, tell your doctor immediately if you notice any signs or symptoms of nerve problems, such as numbness or tingling, muscle weakness, or paralysis.
Arixtra is used for:
Preventing blood clots in patients who will be having certain types of surgery. Arixtra is also used with warfarin to treat blood clots in the leg or lungs. It may also be used for other conditions as determined by your doctor.
Arixtra is an anticoagulant. It works by inhibiting one of the steps necessary for the formation of blood clots, which helps prevent clots from developing or worsening.
Do NOT use Arixtra if:
- you are allergic to any ingredient in Arixtra
- you have severe kidney problems, inflammation of the heart due to a bacterial infection (eg, bacterial endocarditis), active major bleeding, or severe bleeding problems
- you have a low platelet count and the presence of antiplatelet antibodies
- you weigh less than 110 pounds (50 kg) and are using Arixtra to treat a blood clot in the lungs or legs
- you weigh less than 110 pounds (50 kg) and will be having hip or knee replacement surgery or abdominal surgery, or you have had a hip fracture
Contact your doctor or health care provider right away if any of these apply to you.
