†Plasma concentrations.

• Instruct patient to take medication as directed. Adults: Take missed doses as soon as remembered that day. If taking 2.5 mg twice daily, take a single 2.5 mg dose at next scheduled dose. If taking 15 mg twice daily, may take two 15-mg tablets to achieve 30 mg daily dose, then return to regular schedule. If taking 10 mg, 15 mg, or 20 mg once daily, take missed dose immediately; do not double dose. Pediatric Patients: If taken once a day, take missed dose as soon as possible once noticed, but only on the same day. If not possible, skip dose and continue with next dose as prescribed; do not take two doses to make up for a missed dose. If rivaroxaban is taken two times a day, take missed morning dose as soon as possible once it is noticed; a missed morning dose may be taken together with the evening dose. A missed evening dose can only be taken in the same evening. If rivaroxaban is taken three times a day, if a dose is missed, patient should skip missed dose and go back to the regular dosing schedule at the usual time without compensating for missed dose. If patient vomits or spits up dose within 30 min after receiving dose, give a new dose; if >30 min after dose is taken, do not readminister dose; take next dose as scheduled. If patient vomits or spits up dose repeatedly, contact child’s doctor right away. Inform health care professional of missed doses at time of checkup or lab tests. Inform patients that anticoagulant effect may persist for 2–5 days following discontinuation. Advise patient to read the Medication Guide before starting therapy and with each Rx refill in case of changes. Caution patients not to discontinue medication early without consulting health care professional.
• Advise patient to report any symptoms of unusual bleeding or bruising (bleeding gums; nosebleed; black, tarry stools; hematuria; excessive menstrual flow) and symptoms of spinal or epidural hematoma (tingling; numbness, especially in lower extremities; muscular weakness) to health care professional immediately.
• Instruct patient not to drink alcohol or take other Rx, OTC, or herbal products, especially those containing aspirin, NSAIDs, or St. John's wort, or to start or stop any new medications during rivaroxaban therapy without advice of health care professional.
• Advise females of reproductive potential to notify health care professional if pregnancy is planned or suspected, or if breastfeeding. Monitor for bleeding in fetus and/or neonate of women taking rivaroxaban during pregnancy. In pregnant women, rivaroxaban should be used only if potential benefit justifies the potential risk to the mother and fetus.
