Frequently Asked Questions

Can I take a higher dose of Rivaroxaban if my symptoms don't improve?

No. Never increase the dose of Rivaroxaban without medical advice. If your current dose is insufficient, contact your healthcare provider to discuss a dose adjustment or alternative treatment.

What should I do if I miss a dose of my anticoagulant?
