CardiovascularAnticoagulantsBlood Thinners

Drug Class

Direct Oral Anticoagulant (Factor Xa Inhibitor)

Pregnancy

Not assigned a legacy letter (post-2015 labeling). Use during pregnancy is generally avoided because rivaroxaban crosses the placenta and may increase the risk of bleeding in the fetus and during delivery. Low-molecular-weight heparin remains the anticoagulant of choice in pregnancy. An FDA Boxed Warning addresses spinal hematoma risk with neuraxial anesthesia and increased thrombosis risk with premature discontinuation.

Available Forms

Oral tablet (2.5 mg, 10 mg, 15 mg, 20 mg), Starter pack (15 mg and 20 mg combined for first 30 days of DVT/PE treatment), Oral suspension (1 mg/mL after reconstitution)

What It's Used For

is prescribed to treat:

• Preventing blood clots and stroke in atrial fibrillation • Various related conditions in the cardiovascular category • Associated symptoms and complications

It is an important medication that helps manage these conditions effectively.

Dosage Quick Reference

These are general dosage guidelines. Your doctor will determine the appropriate dose for your specific situation.

Condition	Starting Dose	Maintenance Dose
Nonvalvular atrial fibrillation (CrCl > 50 mL/min)	20 mg orally once daily with the evening meal	20 mg once daily; 15 mg if CrCl 15–50 mL/min
DVT / PE treatment	15 mg orally twice daily with food for 21 days	Then 20 mg once daily with food for at least 3 months
DVT / PE recurrence prevention (after ≥ 6 months)	10 mg orally once daily	10 mg once daily, continued indefinitely if risk persists
VTE prophylaxis after hip or knee replacement	10 mg orally once daily, started 6–10 hours after surgery	35 days (hip) or 12 days (knee)
CAD / PAD (with low-dose aspirin)	2.5 mg orally twice daily	2.5 mg twice daily long term

Side Effects

Common side effects may include:

• Nausea or stomach upset • Headache • Dizziness or lightheadedness • Fatigue or tiredness • Mild rash or itching

Serious side effects (seek immediate medical attention):

• Severe allergic reactions (rash, hives, swelling, difficulty breathing) • Unusual bleeding or bruising • Severe stomach pain • Signs of liver problems (yellowing of skin/eyes, dark urine) • Chest pain or irregular heartbeat • Severe dizziness or fainting • Signs of serious adverse effects

Drug Interactions

Rivaroxaban is metabolized by CYP3A4 and is a substrate of P-glycoprotein. Many serious interactions involve combined CYP3A4/P-gp inhibition or induction, or additive bleeding risk.

Strong combined CYP3A4 and P-gp inhibitors (e.g., ketoconazole, itraconazole, ritonavir, lopinavir/ritonavir): Significantly increase rivaroxaban levels and bleeding risk. Co-administration is contraindicated.
Strong combined CYP3A4 and P-gp inducers (e.g., rifampin, phenytoin, carbamazepine, St. John wort): Markedly reduce rivaroxaban exposure and may cause therapeutic failure. Avoid concurrent use.
Other anticoagulants and antiplatelet agents (warfarin, heparins, clopidogrel, prasugrel): Additive bleeding risk. Combine only when clinically necessary (e.g., post-PCI) and for the shortest possible duration.
NSAIDs and aspirin: Increase bleeding risk, particularly GI. Use the lowest effective NSAID dose for the shortest duration; consider PPI co-therapy in higher-risk patients.
SSRIs and SNRIs: Modestly increase bleeding risk through platelet dysfunction. Monitor for bleeding signs.
Dronedarone: Increases rivaroxaban exposure; avoid in patients with reduced renal function.

Frequently Asked Questions

The 15 mg and 20 mg doses must be taken with food to ensure adequate absorption — without food, blood levels drop substantially. The 2.5 mg and 10 mg doses can be taken with or without food. For atrial fibrillation, taking the 20 mg dose with the evening meal helps maintain protective drug levels through the early-morning hours when stroke risk is highest.

For once-daily dosing (15 mg or 20 mg), take the missed dose as soon as you remember on the same day; if it is already the next day, skip it. For twice-daily dosing during DVT/PE treatment, take the missed dose immediately even if it means taking two tablets at once to reach the daily total. Never double-up in a way that exceeds the daily dose. When in doubt, contact your pharmacy.

Yes. Andexanet alfa (Andexxa) is the FDA-approved specific reversal agent for life-threatening bleeding on rivaroxaban or apixaban. Four-factor prothrombin complex concentrate (4F-PCC, e.g., Kcentra) is a non-specific alternative used when andexanet is unavailable. Carry a wallet card or wear medical alert jewelry indicating you take a Factor Xa inhibitor.

Rivaroxaban does not require regular INR monitoring, has fewer dietary restrictions, and produces a more predictable anticoagulant effect. In nonvalvular atrial fibrillation it shows similar stroke prevention to warfarin with significantly less intracranial bleeding. Warfarin remains preferred for mechanical heart valves, moderate-to-severe mitral stenosis, and severe renal impairment.

Seek emergency care for any of the following: severe or unstoppable bleeding (nose, gums, cuts), red or black tarry stools, vomiting blood or material that looks like coffee grounds, pink or brown urine, severe headache, sudden weakness or vision change, or any head injury — even if you feel fine. Routine bruising and minor nosebleeds are common but should be reported if frequent or worsening.

Questions to Ask Your Doctor

Consider discussing these topics at your next appointment:

✓How long do I need to stay on rivaroxaban given my specific clot history or atrial fibrillation?
✓Should my dose be adjusted because of my kidney function?
✓What should I do about rivaroxaban before any procedure, dental work, or surgery?
✓Are there any of my over-the-counter medications or supplements I should stop or change?
