What is rivaroxaban?

Rivaroxaban (Xarelto®) is a blood thinner (also known as an anticoagulant).  It is used to treat patients who have a blood clot. It can also be used to prevent a blood clot from forming in patients who are at risk.

This medicine is available as 10 mg, 15 mg, and 20 mg tablets that are taken by mouth.

Possible side effects of rivaroxaban

  • Easy bruising

Special instructions for rivaroxaban

  • Doses higher than 10 mg should be taken with a meal.
  • Rivaroxaban is taken either one (1) time a day or twice daily depending on what it is being used for. Be sure you understand how you should take this medicine before starting.
    • The dose you are taking may change while you are taking this medicine. Your medical team should make you aware if changes will occur. If you are unsure, contact your medical team right away.
    • Do not stop this medicine unless instructed by your doctor.
  • It is important to take this medicine at about the same time each day and avoid missing doses.
    • If you miss a dose and remember on the same day you were supposed to take it, take it right away (regardless of when the next dose is due).
    • If you miss a dose and remember on a different day than you were supposed to take it, the dose should not be made up. Do not take an extra dose.
  • Tell all medical providers who are caring for you about this medicine.
    • If you are in an accident or experience trauma, make sure the medical team (EMT, emergency room) caring for you is aware that you are taking a blood thinner.
