What is Bevyxxa?
Bevyxxa is used to prevent blood clots in adults who have a serious illness and decreased ability to move. Blood clots are more likely when you are bedridden and you cannot move around.
Bevyxxa may also be used for purposes not listed in this medication guide.
Because Bevyxxa keeps your blood from clotting, this medicine can make it easier for you to bleed. Contact your doctor or seek emergency medical attention if you have unusual bruising or any bleeding that will not stop.
Tell your doctor about all other medicines you use. Many drugs can further increase your risk of bleeding while you are taking Bevyxxa.
Bevyxxa can cause a very serious blood clot around your spinal cord if you undergo a spinal tap or receive spinal anesthesia (epidural), especially if you have a genetic spinal defect, if you have a spinal catheter in place, if you have a history of spinal surgery or repeated spinal taps, or if you are also using other drugs that can affect blood clotting. This type of blood clot can lead to long-term or permanent paralysis.
Get emergency medical help if you have symptoms of a spinal cord blood clot such as back pain, numbness or muscle weakness in your lower body, or loss of bladder or bowel control.
Before taking this medicine
You should not use Bevyxxa if you are allergic to betrixaban, or if you have active or uncontrolled bleeding.
Bevyxxa may cause you to bleed more easily, especially if you have kidney disease or you use other medicines such as:
medicines to treat or prevent blood clots;
certain antidepressants, antibiotics, antifungal medicines, HIV medicines, or heart rhythm medicines; or
aspirin or an NSAID (nonsteroidal anti-inflammatory drug) such as ibuprofen (Advil, Motrin), naproxen (Aleve), diclofenac, indomethacin, or meloxicam.
Bevyxxa can cause a very serious blood clot around your spinal cord if you undergo a spinal tap or receive spinal anesthesia (epidural). This type of blood clot could cause long-term paralysis, and may be more likely to occur if:
you have a genetic spinal defect;
you have a spinal catheter in place or if a catheter has been recently removed;
you have had spinal surgery, or repeated spinal taps or epidural anesthesia; or
you take an NSAID, or use other medicines to treat or prevent blood clots.
To make sure Bevyxxa is safe for you, tell your doctor if you have ever had:
liver or kidney disease;
an artificial heart valve; or
a bleeding or blood clotting disorder.
It is not known whether Bevyxxa will harm an unborn baby. However, taking this medicine during pregnancy may increase the risk of bleeding while you are pregnant or during your delivery. Tell your doctor if you are pregnant or plan to become pregnant.
It is not known whether betrixaban passes into breast milk or if it could affect the nursing baby. Tell your doctor if you are breast-feeding.
How should I take Bevyxxa?
Take Bevyxxa exactly as prescribed by your doctor. Follow all directions on your prescription label. Do not take this medicine in larger or smaller amounts or for longer than recommended.
Bevyxxa is usually taken once per day for up to 42 days. Follow your doctor's dosing instructions very carefully.
Take with food.
Because Bevyxxa keeps your blood from coagulating (clotting) to prevent unwanted blood clots, this medicine can also make it easier for you to bleed. Contact your doctor or seek emergency medical attention if you have unusual bruising, or any bleeding that will not stop.
If you need surgery or dental work, tell the doctor or dentist ahead of time that you take Bevyxxa. You may need to stop taking the medicine for a short time before you have surgery or other medical procedures.
Do not stop taking Bevyxxa unless your doctor tells you to. Stopping suddenly can increase your risk of blood clot or stroke.
Store at room temperature away from moisture and heat.
