What is Xarelto?
Xarelto (rivaroxaban) blocks the activity of certain clotting substances in the blood.
Xarelto is used to prevent or treat a type of blood clot called deep vein thrombosis (DVT), which can lead to blood clots in the lungs (pulmonary embolism). A DVT can occur after knee or hip replacement surgery.
Xarelto is sometimes used to lower your risk of a DVT or PE coming back after you have received treatment for blood clots for at least 6 months.
Xarelto is used in people with atrial fibrillation (a heart rhythm disorder) to lower the risk of stroke caused by a blood clot.
Xarelto is used to help prevent blood clots in certain people hospitalized for an acute illness who are at risk of getting blood clots and who do not have a high risk of bleeding.
Xarelto is also given together with aspirin to lower the risk of stroke, heart attack, or other serious heart problems in people with coronary artery disease (decreased blood flow to the heart) or peripheral artery disease (decreased blood flow to the legs).
Do not stop taking Xarelto without first talking to your doctor. Stopping suddenly can increase your risk of blood clot or stroke.
Xarelto can cause you to bleed more easily. Call your doctor at once if you have signs of bleeding such as: bleeding gums, nosebleeds, heavy menstrual periods or abnormal vaginal bleeding, blood in your urine, bloody or tarry stools, coughing up blood or vomit that looks like coffee grounds, headaches, or dizziness/fainting.
You should not use Xarelto if you have an artificial heart valve.
Many other drugs can increase your risk of bleeding when used with rivaroxaban. Tell your doctor about all medicines you have recently used.
Xarelto can cause a very serious blood clot around your spinal cord if you undergo a spinal tap or receive spinal anesthesia (epidural). Tell any doctor who treats you that you are taking rivaroxaban.
