Compare Xarelto vs. Coumadin

Head-to-head comparisons of medication uses, side effects, warnings, and more.

Key takeaways

Rivaroxaban (Xarelto) and warfarin (Coumadin) are both medications used to prevent and treat blood clots, such as deep vein thrombosis (DVT) and pulmonary embolism (PE). They are both anticoagulants, but they work differently. Rivaroxaban is a direct-acting oral anticoagulant (DOAC) that blocks factor Xa, while warfarin is a vitamin K antagonist that prevents blood clots by blocking vitamin K. Rivaroxaban is taken once or twice daily, depending on the condition, and does not require regular blood tests, while warfarin is typically taken once daily with regular blood tests to monitor international normalized ratio (INR) levels. Rivaroxaban is only available as a brand-name medication, whereas warfarin is available as a lower-cost generic. Bleeding, bruising, and skin discoloration are common side effects of both medications. Rivaroxaban and warfarin can interact with many medications, including other medications that thin the blood such as nonsteroidal anti-inflammatory drugs (NSAIDs). Warfarin requires dietary consistency with vitamin K intake for optimal effects. Both medications have serious bleeding risks, and they both have an antidote available in case of emergency.
