Xarelto (generic: rivaroxaban) is a prescription medication used to prevent certain types of blood clots and strokes. Xarelto can be used in people who are having hip or knee replacement surgery, and for people with an irregular heart rhythm. Xarelto, a "blood thinner", belongs to a group of drugs called factor Xa inhibitors. Factor Xa is an enzyme required for blood to clot. Xarelto inhibits factor Xa, slowing down blood clot formation.

This medication comes in tablet form and is usually taken once daily, with or without food. For people taking it for atrial fibrillation (irregular heart rhythm), Xarelto is taken once daily with the evening meal.

Common side effects of Xarelto include itching, muscle spasms, and bleeding.
