Betrixaban, which is also known as Bevyxxa, is an oral blood thinner that blocks the activity of certain clotting substances in the blood. It is worth noting that blood clots “are more likely when you are bedridden and you cannot move around” (as stated by drugs.com). And because Betrixaban prevents blood clots, this medication can eventually make it easier for you to bleed. However, if you start having uncontrolled bleeding as a result of using Bevyxxa, you should stop using it altogether. You should also call your doctor immediately if you start noticing symptoms associated with spinal blood clot such as back pain, muscle weakness in your lower body, or urinary incontinence. According to the aforementioned website, “headache, dizziness, weakness, feeling like you might pass out” are also some of the side effects that can occur upon taking Bevyxxa. Remember to consult your doctor before using this blood thinner if you are pregnant or you’re planning to conceive, considering it is still not known whether this drug affects an unborn child. Bear in mind that Bevyxxa may not be a safe drug to take while you’re breastfeeding. So, make sure you ask your doctor if you can take it.
