Rivaroxaban 20 mg once daily is used for NVAF or VTE.

• A. True
• B. False
• C. Not applicable
• D. Only VTE

Answer: (A)

Dosing of rivaroxaban is specific to the condition and treatment phase, and 20 mg once daily serves as the maintenance dose for both nonvalvular atrial fibrillation (NVAF) and for long-term treatment of venous thromboembolism (VTE). For NVAF, the standard plan is 20 mg once daily taken with the evening meal. For VTE, treatment starts with 15 mg twice daily for 21 days, then switches to 20 mg once daily (also with meals) for longer-term management. The key is that the 20 mg daily dose is indeed used in both scenarios, though the initial VTE phase uses a different loading regimen.
