What is betrixaban?
Betrixaban blocks the activity of certain clotting substances in the blood.
Betrixaban 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.
Betrixaban may also be used for purposes not listed in this medication guide.
Because betrixaban keeps your blood from clotting, betrixaban 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 betrixaban.
Betrixaban 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.
