FDA boxed warning

WARNING: (A) PREMATURE DISCONTINUATION OF XARELTO INCREASES THE RISK OF THROMBOTIC EVENTS, (B) SPINAL/EPIDURAL HEMATOMA A. Premature discontinuation of XARELTO increases the risk of thrombotic events Premature discontinuation of any oral anticoagulant, including XARELTO, increases the risk of thrombotic events. If anticoagulation with XARELTO is discontinued for a reason other than pathological bleeding or completion of a course of therapy, consider coverage with another anticoagulant [see Dosage and Administration (2.3 , 2.4) , Warnings and Precautions (5.1) , and Clinical Studies (14.1) ] . B. Spinal/epidural hematoma Epidural or spinal hematomas have occurred in patients treated with XARELTO who are receiving neuraxial anesthesia or undergoing spinal puncture. These hematomas may result in long-term or permanent paralysis. Consider these risks when scheduling patients for spinal procedures. Factors that can increase the risk of developing epidural or spinal hematomas in these patients include: use of indwelling epidural catheters concomitant use of other drugs that affect hemostasis, such as non-steroidal anti-inflammatory drugs (NSAIDs), platelet inhibitors, other anticoagulant...

What the FDA label says

Approved uses

XARELTO is a factor Xa inhibitor indicated: to reduce risk of stroke and systemic embolism in nonvalvular atrial fibrillation ( 1.1 ) for treatment of deep vein thrombosis (DVT) ( 1.2 ) for treatment of pulmonary embolism (PE) ( 1.3 ) for reduction in the risk of recurrence of DVT or PE ( 1.4 ) for the prophylaxis of DVT, which may lead to PE in patients undergoing knee or hip replacement surgery ( 1.5 ) for prophylaxis of venous thromboembolism (VTE) in acutely ill medical patients ( 1.6 ) to reduce the risk of major cardiovascular events in patients with coronary artery disease (CAD) ( 1.7 ) to reduce the risk of major thrombotic vascular events in patients with peripheral artery disease (PAD), including patients after recent lower extremity revascularization due to symptomatic PAD ( 1.8 ) for treatment of VTE and reduction in the risk of recurrent VTE in pediatric patients from birth to less than 18 years ( 1.9 ) for thromboprophylaxis in pediatric patients 2 years and older with congenital heart disease after the Fontan procedure ( 1.10 ) 1.1 Reduction of Risk of Stroke and Systemic Embolism in Nonvalvular Atrial Fibrillation XARELTO is indicated to reduce the risk of stroke an...

Contraindications

XARELTO is contraindicated in patients with: active pathological bleeding [see Warnings and Precautions (5.2) ] severe hypersensitivity reaction to XARELTO (e.g., anaphylactic reactions) [see Adverse Reactions (6.2) ] Active pathological bleeding ( 4 ) Severe hypersensitivity reaction to XARELTO ( 4 )

Warnings and precautions

Risk of bleeding: XARELTO can cause serious and fatal bleeding ( 5.2 ) Pregnancy-related hemorrhage: Use XARELTO with caution in pregnant women due to the potential for obstetric hemorrhage and/or emergent delivery ( 5.7 , 8.1 ) Prosthetic heart valves: XARELTO use not recommended ( 5.8 ) Increased Risk of Thrombosis in Patients with Triple Positive Antiphospholipid Syndrome: XARELTO use not recommended ( 5.10 ) 5.1 Increased Risk of Thrombotic Events after Premature Discontinuation Premature discontinuation of any oral anticoagulant, including XARELTO, in the absence of adequate alternative anticoagulation increases the risk of thrombotic events. An increased rate of stroke was observed during the transition from XARELTO to warfarin in clinical trials in atrial fibrillation patients. If XARELTO is discontinued for a reason other than pathological bleeding or completion of a course of therapy, consider coverage with another anticoagulant [see Dosage and Administration (2.3 , 2.4) and Clinical Studies (14.1) ] . 5.2 Risk of Bleeding XARELTO increases the risk of bleeding, including in any organ, and can cause serious or fatal bleeding. In deciding whether to prescribe XARELTO to pat...

Adverse reactions (label)

The following clinically significant adverse reactions are also discussed in other sections of the labeling: Increased Risk of Stroke After Discontinuation in Nonvalvular Atrial Fibrillation [see Boxed Warning and Warnings and Precautions (5.1) ] Bleeding Risk [see Warnings and Precautions (5.2 , 5.4 , 5.5 , 5.6 , 5.7) ] Spinal/Epidural Hematoma [see Boxed Warning and Warnings and Precautions (5.3) ] The most common adverse reaction (>5%) in adult patients was bleeding ( 6.1 ) The most common adverse reactions (>10%) in pediatric patients were bleeding, cough, vomiting, and gastroenteritis ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Janssen Pharmaceuticals, Inc. at 1-800-526-7736 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice. During clinical development for the approved indications, 34,947 adult patients were exposed to XARELTO. Hemorrhage The most common adverse reacti...

Side-effect reports sent to the FDA

These are counts of reports people filed, not rates of harm. Anyone can file one, and nobody checks whether the drug was the cause. Millions of doses are taken for every report sent, so the useful part is how this drug compares with the average across all drugs.

192,118reports that mention this drug
191,292of those blame this drug, not another one the person was taking
83%of reports describe a serious outcome, such as a hospital stay (average for all drugs: 57%)
13.3%of reports include a death, from any cause (average for all drugs: 9.1%)

2,771 reports blaming this drug for every million Medicare prescriptions filled, which is 1.0× the typical drug on this site. (18,458 reports in 2024–2026, against 6,660,246 Medicare fills in one year. This is the one number here that accounts for how many people take the drug.)

Counts measure how much evidence exists and how transparent it is, not how big the benefit is. For that, ask your prescriber: if 100 people like me took this, how many would get better because of it, and how many would be harmed? (Doctors call these the "number needed to treat" and "number needed to harm.") It differs by condition and is the number drug ads leave out. Sources: PubMed, ClinicalTrials.gov.

Questions to ask your prescriber

  1. This drug carries a boxed warning. Which specific risk does it cover, and does it apply to me?
  2. The most-reported problems in FDA's adverse event data are gastrointestinal haemorrhage, haemorrhage, dyspnoea. How would we recognize and handle those?
  3. Off-label use is among the most-reported items for this drug. Is my use on-label, and if not, what evidence supports it?
  4. Why this one over apixaban, betrixaban, edoxaban? What would make you pick one of those instead?
  5. The manufacturer pays physicians heavily to promote this drug. Have you received anything from them?
  6. What result are we expecting, by when, and what is the plan if it does not happen?
  7. If 100 people like me took this drug, how many would actually get better because of it, and how many would be harmed by it? (Doctors call these the number needed to treat and the number needed to harm.)
