From the Guidelines

Xarelto (rivaroxaban) should be taken once daily with the evening meal to ensure adequate absorption. This recommendation is based on the guidelines provided by the American College of Cardiology/American Heart Association Task Force on Practice Guidelines and the Heart Rhythm Society, as stated in the 2014 AHA/ACC/HRS guideline for the management of patients with atrial fibrillation 1. The guideline specifically mentions that rivaroxaban should be administered as a single daily dose with the evening meal.

Key Considerations

  • For patients taking the 15mg or 20mg dose for conditions like atrial fibrillation or deep vein thrombosis, evening administration is recommended.
  • It's essential to take Xarelto at the same time each day to maintain consistent blood levels of the medication.
  • Never skip doses, as this can increase your risk of blood clots.
  • If you miss a dose, take it as soon as you remember on the same day, but never take a double dose to make up for a missed one.
  • Evening dosing is often preferred because if bleeding complications occur, they can be addressed during waking hours.

Additional Guidance

The American Heart Association and American Stroke Association also published an advisory on oral antithrombotics for stroke prevention in nonvalvular atrial fibrillation, which supports the use of rivaroxaban as a reasonable alternative to warfarin in patients at moderate to high risk of stroke 1. However, the primary consideration for the timing of Xarelto administration remains the guideline recommendation for evening dosing with food to ensure adequate absorption 1.

From the FDA Drug Label

If you take XARELTO for: Atrial fibrillation that is not caused by a heart valve problem: Take XARELTO 1 time a day with your evening meal Blood clots in the veins of your legs or lungs: Take XARELTO 1 or 2 times a day as prescribed by your doctor. Hip or knee replacement surgery: Take XARELTO 1 time a day with or without food. Blood clots in people hospitalized for an acute illness: Take XARELTO 1 time a day, with or without food Reducing the risk of serious heart problems, heart attack and stroke in coronary artery disease: Take XARELTO 2.5 mg 2 times a day with or without food. Reducing the risk of a sudden decrease in blood flow to the legs, major amputation, serious heart problems or stroke in people with peripheral artery disease including those who have recently had a procedure to improve blood flow to the legs: Take XARELTO 2.5 mg 2 times a day with or without food.

The time XARELTO should be taken depends on the condition being treated.

  • For atrial fibrillation, take XARELTO 1 time a day with your evening meal.
  • For blood clots in the veins of your legs or lungs, take XARELTO 1 or 2 times a day as prescribed by your doctor.
  • For hip or knee replacement surgery, take XARELTO 1 time a day with or without food.
  • For blood clots in people hospitalized for an acute illness, take XARELTO 1 time a day with or without food.
  • For reducing the risk of serious heart problems, heart attack and stroke in coronary artery disease or peripheral artery disease, take XARELTO 2.5 mg 2 times a day with or without food. 2

From the Research

Xarelto Dosage Timing

  • The studies provided do not specify the exact time of day when Xarelto (rivaroxaban) should be taken 3, 4, 5, 6, 7.
  • However, it is mentioned that rivaroxaban is a once-daily oral anticoagulant, which implies that it can be taken at any time of day, as long as it is taken consistently at the same time every day 3, 4.
  • The dosage of rivaroxaban is typically 20 mg daily for patients with normal renal function and 15 mg daily for those with reduced renal function 4.
  • It is essential to follow the prescribed dosage and administration instructions provided by a healthcare professional to ensure the safe and effective use of rivaroxaban.

Factors Influencing Dosage Timing

  • Renal function is a crucial factor in determining the dosage of rivaroxaban, and patients with reduced renal function may require a lower dose 4, 5.
  • Other factors, such as prior stroke or transient ischemic attack, reduced renal function, prior myocardial infarction, peripheral artery disease, heart failure, or age ≥ 75 years, may also influence the treatment effect of rivaroxaban 7.
  • However, these factors do not appear to affect the timing of dosage, but rather the dosage itself or the overall treatment strategy.
