Drug Interactions
Rivaroxaban is metabolized by CYP3A4 and is a substrate of P-glycoprotein. Many serious interactions involve combined CYP3A4/P-gp inhibition or induction, or additive bleeding risk.
- Strong combined CYP3A4 and P-gp inhibitors (e.g., ketoconazole, itraconazole, ritonavir, lopinavir/ritonavir): Significantly increase rivaroxaban levels and bleeding risk. Co-administration is contraindicated.
- Strong combined CYP3A4 and P-gp inducers (e.g., rifampin, phenytoin, carbamazepine, St. John wort): Markedly reduce rivaroxaban exposure and may cause therapeutic failure. Avoid concurrent use.
- Other anticoagulants and antiplatelet agents (warfarin, heparins, clopidogrel, prasugrel): Additive bleeding risk. Combine only when clinically necessary (e.g., post-PCI) and for the shortest possible duration.
- NSAIDs and aspirin: Increase bleeding risk, particularly GI. Use the lowest effective NSAID dose for the shortest duration; consider PPI co-therapy in higher-risk patients.
- SSRIs and SNRIs: Modestly increase bleeding risk through platelet dysfunction. Monitor for bleeding signs.
- Dronedarone: Increases rivaroxaban exposure; avoid in patients with reduced renal function.
