Side-by-Side Comparison
Every dose decision below belongs to your prescriber. The table describes what the labels say in general terms, not what you should take.
| Feature | Apixaban (Eliquis) | Rivaroxaban (Xarelto) |
|---|---|---|
| Drug class | Factor Xa inhibitor anticoagulant; blocks a natural substance that helps clots form (MedlinePlus, 2025; FDA, 2012) | Factor Xa inhibitor anticoagulant; same clotting target (Drugs.com, undated; FDA, 2018) |
| How it's taken | Tablet by mouth, with or without food (MedlinePlus, 2025) | Tablet by mouth; the label directs certain uses to be taken with food or with the evening meal (FDA, 2018) |
| How often | Twice a day, at around the same times each day (MedlinePlus, 2025) | Once daily for atrial fibrillation; twice daily for an initial period in clot treatment, then once daily (FDA, 2018) |
| Common side effects | The most common adverse reactions are bleeding-related (FDA, 2012) | Bleeding was the most common adverse reaction (FDA, 2018) |
| One notable difference | The prescriber adjusts the amount using a combination of age, body weight and a kidney blood test (FDA, 2012) | The prescriber adjusts the amount using measured kidney function, creatinine clearance (FDA, 2018) |
Neither medicine is recommended for people with prosthetic heart valves (FDA, 2012; FDA, 2018). Both carry warnings about blood clots forming near the spine if you have epidural or spinal anesthesia or a spinal injection while taking them (MedlinePlus, 2025; FDA, 2018) — tell any anesthesiologist, surgeon or dentist which anticoagulant you are on.
