What is rivaroxaban?
Blood clots can develop when you are very ill and cannot move around as much as normal, such as during or after a stay in the hospital. Blood clots may also develop after knee or hip replacement surgery.
Rivaroxaban is sometimes used to lower your risk of a blood clot coming back after you have received treatment for blood clots for at least 6 months.
Rivaroxaban is also used in people with atrial fibrillation (a heart rhythm disorder) to lower the risk of stroke caused by a blood clot.
Rivaroxaban 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).
Rivaroxaban may also be used for purposes not listed in this medication guide.
Do not stop taking rivaroxaban without first talking to your doctor. Stopping suddenly can increase your risk of blood clot or stroke.
Call your doctor at once if you have signs of bleeding such as: headaches, feeling very weak or dizzy, 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.
Many other drugs can increase your risk of bleeding when used with rivaroxaban. Tell your doctor about all medicines you have recently used.
Rivaroxaban 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.
