Question: how long does it take xarelto to take effect?
Answer: Xarelto® (rivaroxaban) begins to reduce blood clotting within a few hours after the first dose. If you stop taking it, its effect on clotting begins to wear off within 24 hours for most people. Take it exactly prescribed by your doctor and at the same time each day. You MUST take the 15 mg and 20 mg tablets with food.
