Precautions while using betrixaban
It is very important that your doctor check your progress at regular visits to make sure that betrixaban is working properly and to decide if you should continue to take it. Blood tests may be needed to check for unwanted effects.
Check with your doctor right away if you have any unusual bleeding or bruising, black, tarry stools, blood in the urine or stools, headache, dizziness, or weakness, pain, swelling, or discomfort in a joint, pinpoint red spots on your skin, unusual nosebleeds, or unusual vaginal bleeding that is heavier than normal. These may be signs of bleeding problems.
Be extra careful to avoid injuries. Stay away from rough sports or other situations where you could be bruised, cut, or injured. Gently brush and floss your teeth. Be careful when using sharp objects, including razors and fingernail clippers.
Betrixaban may increase the risk of blood clots in the spine or epidural area, which may lead to long-term or permanent paralysis. This is more likely to occur if you have an epidural catheter placed in your back, are taking NSAID or blood clotting medicine, a history of repeated epidural punctures or problems with your spine, or have had surgery on your spine. Tell your doctor right away if you have tingling, numbness, or muscle weakness, especially in your legs and feet.
Make sure any doctor who treats you knows that you are using betrixaban. You may need to stop using betrixaban for several days before having surgery, including dental procedures.
