Tell your doctor you are using rivaroxaban before having certain spinal procedures (spinal puncture or spinal/epidural anesthesia). Using this medication before these procedures has rarely caused major bleeding or blood clots in or around the spine. This effect may cause loss of muscle function (paralysis) that can be permanent. The risk is increased if you have a history of spinal surgery, or spinal deformity, or receive pain medication through a tube placed in the spine (epidural catheter). Also, the risk is higher if you use other \"blood thinning\" or anti-platelet medications such as aspirin, clopidogrel, warfarin, or nonsteroidal anti-inflammatory drugs (NSAIDs) including ibuprofen or naproxen. Discuss the risks and benefits of treatment with your doctor. Tell your doctor right away if you have any symptoms such as tingling, numbness (especially in the legs), or muscle weakness.
If you have a certain irregular heartbeat (atrial fibrillation), you have a higher chance of forming a blood clot in the heart that can travel to the brain and cause a stroke, or to other parts of the body. If you are taking rivaroxaban to prevent these harmful blood clots and have to stop taking it, you may have a higher risk of forming a blood clot. Your doctor may direct you to take a different \"blood thinning\" or anti-platelet medication to reduce your risk. Get medical help right away if you have any of the following symptoms: chest/jaw/left arm pain, shortness of breath, unusual sweating, weakness on one side of the body, slurred speech, sudden vision changes, or confusion.

This medication is used to prevent harmful blood clots (for example, in your legs or lungs) from forming after hip or knee replacement surgery. Rivaroxaban is also approved for use to help prevent strokes and harmful blood clots that may form due to a certain irregular heartbeat (atrial fibrillation). In Canada, this medication is also used to treat harmful blood clots in the legs.
Rivaroxaban is an anticoagulant that works by blocking certain clotting proteins in your blood.
