Xarelto is the brand name for rivaroxaban, a direct oral anticoagulant (DOAC) that inhibits factor Xa to help prevent or treat blood clots.
Typical uses
- Reduce stroke risk in nonvalvular atrial fibrillation
- Treat DVT (deep vein thrombosis) or PE (pulmonary embolism)
- Prevent DVT after certain surgeries (e.g., hip or knee replacement)
How it’s taken and dose
- Dosing depends on the condition and kidney function. Some regimens must be taken with food; others may not. Your doctor will give you the exact dose and instructions.
- There’s no routine INR test for rivaroxaban like there is with warfarin, but kidney function, liver enzymes, and bleeding risk are monitored as needed.
What to know about safety
- Common side effects: unusual bleeding or bruising, nosebleeds, heavier menstrual bleeding, and sometimes anemia, nausea, or stomach upset.
- Serious bleeding risk: can occur; symptoms include severe/extreme bleeding, blood in urine or stool, coughing up blood, or vomiting blood. Seek urgent medical care if you have unusual or heavy bleeding.
- Neuraxial anesthesia (spinal/epidural) with rivaroxaban increases risk of spinal hematoma; tell your healthcare team if you’re having anesthesia.
- Not for use in pregnancy or when breastfeeding unless specifically advised by a clinician. Do not use if you have active major bleeding or certain severe liver problems.
- Interactions: avoid or limit other anticoagulants/antiplatelets unless your clinician says it’s safe. Be cautious with NSAIDs (like ibuprofen, naproxen) and with strong inhibitors or inducers of CYP3A4 and P-glycoprotein (e.g., certain antifungals, HIV meds, st. John’s wort, rifampin). Always tell your prescriber about all medicines and supplements you take.
If you’re asking about your own situation
- Are you being treated for a specific condition (AF, DVT/PE, or post-surgery prophylaxis)?
- Do you have kidney or liver problems, or are you taking other blood thinners or NSAIDs?
- Are you pregnant or breastfeeding, or planning surgery soon?
