Rivaroxaban Renal Dose Adjustment Calculator

Adjust rivaroxaban dosing for renal impairment in atrial fibrillation and VTE, reducing dose from 20 mg to 15 mg OD for AF at CrCl 15-49 and assessing contraindication thresholds below CrCl 15 mL/min.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Adjust rivaroxaban dosing for renal impairment in atrial fibrillation and VTE, reducing dose from 20 mg to 15 mg OD for AF at CrCl 15-49 and assessing contraindication thresholds below CrCl 15 mL/min

Each component has a specific meaning:

  • 20 mg — The 20 mg recorded for the scenario being assessed.

Note: Interpret the rivaroxaban renal dose result against the thresholds and context described above.

How to Use

Enter the 20 mg for the scenario you are assessing. Adjust rivaroxaban dosing for renal impairment in atrial fibrillation and VTE, reducing dose from 20 mg to 15 mg OD for AF at CrCl 15-49 and assessing contraindication thresholds below CrCl 15 mL/min. Use the rivaroxaban renal dose result to inform your calculation.
