Rivaroxaban

What is Rivaroxaban?

Rivaroxaban is a once-daily oral anticoagulant that lowers the risk of harmful blood clots without routine INR testing.

How it works

It directly inhibits factor Xa, reducing thrombin generation and clot formation throughout the body.

Common uses

• Preventing stroke in non-valvular atrial fibrillation
• Treating deep vein thrombosis or pulmonary embolism
• Preventing clots after knee or hip replacement surgery

Monitoring & Safety

• Labs: Kidney labs (creatinine, egfr, bun) guide dosing and safety.
• Main risk is bleeding; easy bruising and nosebleeds are common early signs.

Dosing (简要)

• Doses vary by indication; many regimens are once daily with food to improve absorption.
• Take at the same time every day; do not double up if a dose is missed.

Drug interactions

• Strong CYP3A4 or P-gp inhibitors/inducers can change drug levels.
• Other blood thinners or antiplatelets increase bleeding risk.
