🩺 Clinical
Rivaroxaban is used to: prevent and treat deep vein thrombosis (DVT; a blood clot) and pulmonary embolism (PE; a blood clot in the lung). lower the risk of a heart attack, stroke, or death in people with coronary artery disease (narrowing of the blood vessels that bring blood to the heart) or peripheral arterial disease (poor blood flow to the arms and legs). Rivaroxaban is in a class of medications called factor Xa inhibitors. It works by blocking a natural substance that helps blood clots to form.

🚨 Boxed Warning ▾
WARNING: (A) PREMATURE DISCONTINUATION OF RIVAROXABAN FOR ORAL SUSPENSION INCREASES THE RISK OF THROMBOTIC EVENTS, (B) SPINAL/EPIDURAL HEMATOMA A. Premature discontinuation of rivaroxaban for oral suspension increases the risk of thrombotic events Premature discontinuation of any oral anticoagulant, including rivaroxaban for oral suspension, increases the risk of thrombotic events. If anticoagulation with rivaroxaban for oral suspension 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 )].
B. Spinal/epidural hematoma Epidural or spinal hematomas have occurred in patients treated with rivaroxaban for oral suspension 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 anticoagulants • a history of traumatic or repeated epidural or spinal punctures • a history of spinal deformity or spinal surgery • optimal timing between the administration of rivaroxaban for oral suspension and neuraxial procedures is not known [see Warnings and Precautions ( 5.2 , 5.3 ) and Adverse Reactions ( 6.2 )].
Monitor patients frequently for signs and symptoms of neurological impairment. If neurological compromise is noted, urgent treatment is necessary [see Warnings and Precautions ( 5.3 )]. Consider the benefits and risks before neuraxial intervention in patients anticoagulated or to be anticoagulated for thromboprophylaxis [see Warnings and Precautions ( 5.3 )].

Its use is therefore not recommended in children less than 6 months of age with any of the following: Less than 37 weeks of gestation at birth Less than 10 days of oral feeding Body weight of less than 2.6 kg. To increase absorption, all doses should be taken with feeding or with food. Monitor the child’s weight and review the dose regularly, especially for children below 12 kg.
This is to ensure a therapeutic dose is maintained. All pediatric patients (except less than 2 years old with catheter-related thrombosis): Therapy with rivaroxaban for oral suspension should be continued for at least 3 months in children with thrombosis. Treatment can be extended up to 12 months when clinically necessary.
The benefit of continued therapy beyond 3 months should be assessed on an individual basis taking into account the risk for recurrent thrombosis versus the potential risk of bleeding. Pediatric patients less than 2 years old with catheter-related thrombosis: Therapy with rivaroxaban for oral suspension should be continued for at least 1 month in children less than 2 years old with catheter-related thrombosis. Treatment can be extended up to 3 months when clinically necessary.

⛔ Contraindications ▾
4 CONTRAINDICATIONS Rivaroxaban is contraindicated in patients with: active pathological bleeding [see Warnings and Precautions (5.2) ] severe hypersensitivity reaction to rivaroxaban for oral suspension (e.g., anaphylactic reactions) [see Adverse Reactions (6.2) ] Active pathological bleeding ( 4 ) Severe hypersensitivity reaction to rivaroxaban for oral suspension ( 4 )
⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Risk of bleeding: Rivaroxaban for oral suspension can cause serious and fatal bleeding. An agent to reverse the activity of rivaroxaban is available. ( 5.2 ) Pregnancy-related hemorrhage: Use rivaroxaban for oral suspension with caution in pregnant women due to the potential for obstetric hemorrhage and/or emergent delivery.
( 5.7 , 8.1 ) Prosthetic heart valves: Rivaroxaban for oral suspension use not recommended. ( 5.8 ) Increased Risk of Thrombosis in Patients with Triple Positive Antiphospholipid Syndrome: Rivaroxaban for oral suspension use not recommended. ( 5.10 )
5.1Increased Risk of Thrombotic Events after Premature Discontinuation Premature discontinuation of any oral anticoagulant, including rivaroxaban, 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 tablets to warfarin in clinical trials in another indication in patients. If rivaroxaban 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 )] .
5.2Risk of Bleeding Rivaroxaban increases the risk of bleeding, including in any organ, and can cause serious or fatal bleeding. In deciding whether to prescribe rivaroxaban to patients at increased risk of bleeding, the risk of thrombotic events should be weighed against the risk of bleeding. Promptly evaluate any signs or symptoms of blood loss and consider the need for blood replacement.
Discontinue rivaroxaban in patients with active pathological hemorrhage. The terminal elimination half-life of rivaroxaban is 5 to 9 hours in healthy subjects aged 20 to 45 years. Concomitant use of other drugs that impair hemostasis increases the risk of bleeding.
These include aspirin, P2Y 12 platelet inhibitors, dual antiplatelet therapy, other antithrombotic agents, fibrinolytic therapy, non-steroidal anti-inflammatory drugs (NSAIDs) [see Drug Interactions (7.4) ] , selective serotonin reuptake inhibitors, and serotonin norepinephrine reuptake inhibitors. Concomitant use of drugs that are known combined P-gp and strong CYP3A inhibitors increases rivaroxaban exposure and may increase bleeding risk [see Drug Interactions (7.2) ] . Risk of Hemorrhage in Acutely Ill Medical Patients at High Risk of Bleeding Acutely ill medical patients with the following conditions are at increased risk of bleeding with the use of rivaroxaban for primary VTE prophylaxis: history of bronchiectasis, pulmonary cavitation, or pulmonary hemorrhage, active cancer (i.e., undergoing acute, in-hospital cancer treatment), active gastroduodenal ulcer in the three months prior to treatment, history of bleeding in the three months prior to treatment, or dual antiplatelet therapy.
Rivaroxaban is not for use for primary VTE prophylaxis in these hospitalized, acutely ill medical patients at high risk of bleeding. Reversal of Anticoagulant Effect An agent to reverse the anti-factor Xa activity of rivaroxaban is available. Because of high plasma protein binding, rivaroxaban is not dialyzable [see Clinical Pharmacology ( 12.3 )] .
Protamine sulfate and vitamin K are not expected to affect the anticoagulant activity of rivaroxaban. Use of procoagulant reversal agents, such as prothrombin complex concentrate (PCC), activated prothrombin complex concentrate or recombinant factor VIIa, may be considered but has not been evaluated in clinical efficacy and safety studies. Monitoring for the anticoagulation effect of rivaroxaban using a clotting test (PT, INR or aPTT) or anti-factor Xa (FXa) activity is not recommended.
5.3Spinal/Epidural Anesthesia or Puncture When neuraxial anesthesia (spinal/epidural anesthesia) or spinal puncture is employed, patients treated with anticoagulant agents for prevention of thromboembolic complications are at risk of developing an epidural or spinal hematoma which…

6.1Clinical 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. Pediatric Patients Treatment of Venous Thromboembolism and Reduction in Risk of Recurrent Venous Thromboembolism in Pediatric Patients The safety assessment is based on data from the EINSTEIN Junior Phase 3 study in 491 patients from birth to less than 18 years of age.
Patients were randomized 2:1 to receive body weight- adjusted doses of rivaroxaban or comparator (unfractionated heparin, low molecular weight heparin, fondaparinux or VKA). Discontinuation due to bleeding events occurred in 6 (1.8%) patients in the rivaroxaban group and 3 (1.9%) patients in the comparator group. Table 14 shows the number of patients experiencing bleeding events in the EINSTEIN Junior study.
In female patients who had experienced menarche, ages 12 to less than 18 years of age, menorrhagia occurred in 23 (27%) female patients in the rivaroxaban group and 5 (10%) female patients in the comparator group.

🔄 Drug Interactions ▾
7 DRUG INTERACTIONS Avoid combined P-gp and strong CYP3A inhibitors and inducers ( 7.2 , 7.3) Anticoagulants: Avoid concomitant use ( 7.4 )
7.1General Inhibition and Induction Properties Rivaroxaban is a substrate of CYP3A4/5, CYP2J2, and the P-gp and ATP-binding cassette G2 (ABCG2) transporters. Combined P-gp and strong CYP3A inhibitors increase exposure to rivaroxaban and may increase the risk of bleeding. Combined P-gp and strong CYP3A inducers decrease exposure to rivaroxaban and may increase the risk of thromboembolic events.
7.2Drugs that Inhibit Cytochrome P450 3A Enzymes and Drug Transport Systems Interaction with Combined P-gp and Strong CYP3A Inhibitors Avoid concomitant administration of rivaroxaban with known combined P-gp and strong CYP3A inhibitors (e.g., ketoconazole and ritonavir) [see Warnings and Precautions (5.6) and Clinical Pharmacology (12.3)] . Although clarithromycin is a combined P-gp and strong CYP3A inhibitor, pharmacokinetic data suggests that no precautions are necessary with concomitant administration with rivaroxaban as the change in exposure is unlikely to affect the bleeding risk [see Clinical Pharmacology (12.3) ] .
Interaction with Combined P-gp and Moderate CYP3A Inhibitors in Patients with Renal Impairment Rivaroxaban should not be used in patients with CrCl 15 to less than 80 mL/min who are receiving concomitant combined P-gp and moderate CYP3A inhibitors (e.g., erythromycin) unless the potential benefit justifies the potential risk [see Warnings and Precautions (5.4) and Clinical Pharmacology (12.3) ] .
7.3Drugs that Induce Cytochrome P450 3A Enzymes and Drug Transport Systems Avoid concomitant use of rivaroxaban with drugs that are combined P-gp and strong CYP3A inducers (e.g., carbamazepine, phenytoin, rifampin, St. John’s wort) [see Warnings and Precautions (5.6) and Clinical Pharmacology (12.3) ] .
7.4Anticoagulants and NSAIDs/Aspirin Coadministration of enoxaparin, warfarin, aspirin, clopidogrel and chronic NSAID use may increase the risk of bleeding [see Clinical Pharmacology (12.3) ]. Avoid concurrent use of rivaroxaban with other anticoagulants due to increased bleeding risk unless benefit outweighs risk. Promptly evaluate any signs or symptoms of blood loss if patients are treated concomitantly with aspirin, other platelet aggregation inhibitors, or NSAIDs [see Warnings and Precautions (5.2) ] .
👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS Renal impairment: Avoid or adjust dose ( 8.6 ) Hepatic impairment: Avoid use in Child-Pugh B and C hepatic impairment or hepatic disease associated with coagulopathy ( 8.7 )
8.1Pregnancy Risk Summary The limited available data on rivaroxaban in pregnant women are insufficient to inform a drug- associated risk of adverse developmental outcomes. Use rivaroxaban with caution in pregnant patients because of the potential for pregnancy related hemorrhage and/or emergent delivery. The anticoagulant effect of rivaroxaban cannot be reliably monitored with standard laboratory testing.
Consider the benefits and risks of rivaroxaban for the mother and possible risks to the fetus when prescribing rivaroxaban to a pregnant woman [see Warnings and Precautions ( 5.2 , 5.7 )] . Adverse outcomes in pregnancy occur regardless of the health of the mother or the use of medications. The estimated background risk of major birth defects and miscarriage for the indicated populations is unknown.
In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. Clinical Considerations Disease-Associated Maternal and/or Embryo/Fetal Risk Pregnancy is a risk factor for venous thromboembolism and that risk is increased in women with inherited or acquired thrombophilias. Pregnant women with thromboembolic disease have an increased risk of maternal complications including pre-eclampsia.
Maternal thromboembolic disease increases the risk for intrauterine growth restriction, placental abruption and early and late pregnancy loss. Fetal/Neonatal Adverse Reactions Based on the pharmacologic activity of Factor Xa inhibitors and the potential to cross the placenta, bleeding may occur at any site in the fetus and/or neonate. Labor or Delivery All patients receiving anticoagulants, including pregnant women, are at risk for bleeding and this risk may be increased during labor or delivery [see Warnings and Precautions (5.7) ].
The risk of bleeding should be balanced with the risk of thrombotic events when considering the use of rivaroxaban in this setting. Data Human Data There are no adequate or well-controlled studies of rivaroxaban in pregnant women, and dosing for pregnant women has not been established. Post-marketing experience is currently insufficient to determine a rivaroxaban-associated risk for major birth defects or miscarriage.
In an in vitro placenta perfusion model, unbound rivaroxaban was rapidly transferred across the human placenta. Animal Data Rivaroxaban crosses the placenta in animals. Rivaroxaban increased fetal toxicity (increased resorptions, decreased number of live fetuses, and decreased fetal body weight) when pregnant rabbits were given oral doses of ≥10 mg/kg rivaroxaban during the period of organogenesis.
This dose corresponds to about 4 times the human exposure of unbound drug, based on AUC comparisons at the highest recommended human dose of 20 mg/day. Fetal body weights decreased when pregnant rats were given oral doses of 120 mg/kg during the period of organogenesis. This dose corresponds to about 14 times the human exposure of unbound drug.
In rats, peripartal maternal bleeding and maternal and fetal death occurred at the rivaroxaban dose of 40 mg/kg (about 6 times maximum human exposure of the unbound drug at the human dose of 20 mg/day).
8.2Lactation Risk Summary Rivaroxaban has been detected in human milk. There are insufficient data to determine the effects of rivaroxaban on the breastfed child or on milk production. Rivaroxaban and/or its metabolites were present in the milk of rats.
The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for rivaroxaban and any potential adverse effects on the breastfed infant from rivaroxaban or from the underlying maternal condition (see Data) .

🧒 Pediatric Use ▾
8.4Pediatric Use The safety and effectiveness of rivaroxaban have been established in pediatric patients from birth to less than 18 years for the treatment of VTE and the reduction in risk of recurrent VTE. Use of rivaroxaban is supported in these age groups by evidence from adequate and well-controlled studies of rivaroxaban in adults with additional pharmacokinetic, safety and efficacy data from a multicenter, prospective, open-label, active-controlled randomized study in 500 pediatric patients from birth to less than 18 years of age.
Rivaroxaban was not studied and therefore dosing cannot be reliably determined or recommended in children less than 6 months who were less than 37 weeks of gestation at birth; had less than 10 days of oral feeding, or had a body weight of less than 2.6 kg [see Dosage and Administration (2.2 ), Adverse Reactions (6.1) , Clinical Pharmacology (12.3) and Clinical Studies (14.8 )] . The safety and effectiveness of rivaroxaban have been established for use in pediatric patients aged 2 years and older with congenital heart disease who have undergone the Fontan procedure.
Use of rivaroxaban is supported in these age groups by evidence from adequate and well- controlled studies of rivaroxaban in adults with additional data from a multicenter, prospective, open-label, active controlled study in 112 pediatric patients to evaluate the single- and multiple- dose pharmacokinetic properties of rivaroxaban and the safety and efficacy of rivaroxaban when used for thromboprophylaxis for 12 months in children with single ventricle physiology who had the Fontan procedure [see Dosage and Administration (2.2 ), Adverse Reactions (6.1) , Clinical Pharmacology (12.3) and Clinical Studies (14.9) ] .
Although not all adverse reactions identified in the adult population have been observed in clinical trials of children and adolescent patients, the same warnings and precautions for adults should be considered for children and adolescents.
🧓 Geriatric Use ▾
8.5Geriatric Use Of the total number of adult patients in clinical trials for the approved indications of rivaroxaban (N=64,943 patients), 64 percent were 65 years and over, with 27 percent 75 years and over. In clinical trials the efficacy of rivaroxaban in the elderly (65 years or older) was similar to that seen in patients younger than 65 years. Both thrombotic and bleeding event rates were higher in these older patients [see Clinical Pharmacology (12.3) and Clinical Studies (14) ] .
🆘 Overdosage ▾
10 OVERDOSAGE Overdose of rivaroxaban may lead to hemorrhage. Discontinue rivaroxaban and initiate appropriate therapy if bleeding complications associated with overdosage occur. Rivaroxaban systemic exposure is not further increased at single doses less than 50 mg due to limited absorption.
The use of activated charcoal to reduce absorption in case of rivaroxaban overdose may be considered. Due to the high plasma protein binding, rivaroxaban is not dialyzable [see Warnings and Precautions (5.2) and Clinical Pharmacology (12.3) ] . Partial reversal of laboratory anticoagulation parameters may be achieved with use of plasma products.
An agent to reverse the anti-factor Xa activity of rivaroxaban is available.

12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Rivaroxaban is a selective inhibitor of FXa. It does not require a cofactor (such as Anti-thrombin III) for activity. Rivaroxaban inhibits free FXa and prothrombinase activity. Rivaroxaban has no direct effect on platelet aggregation, but indirectly inhibits platelet aggregation induced by thrombin. By inhibiting FXa, rivaroxaban decreases thrombin generation.
12.2Pharmacodynamics Rivaroxaban produces dose-dependent inhibition of FXa activity. Clotting tests, such as prothrombin time (PT), activated partial thromboplastin time (aPTT) and HepTest ® , are also prolonged dose-dependently. In children treated with rivaroxaban, the correlation between anti-factor Xa to plasma concentrations is linear with a slope close to 1.
Monitoring for anticoagulation effect of rivaroxaban using anti-FXa activity or a clotting test is not recommended. Specific Populations Renal Impairment The relationship between systemic exposure and pharmacodynamic activity of rivaroxaban was altered in adult subjects with renal impairment relative to healthy control subjects [see Use in Specific Populations (8.6) ] . Table 18: Percentage Increase in Rivaroxaban PK and PD Measures in Adult Subjects with Renal Impairment Relative to Healthy Subjects from Clinical Pharmacology Studies Measure Parameter Creatinine Clearance (mL/min) 50 to 79 30 to 49 15 to 29 ESRD (on dialysis)* ESRD (post-dialysis)* Exposure AUC 44 52 64 47 56 FXa Inhibition AUEC 50 86 100 49 33 PT Prolongation AUEC 33 116 144 112 158 * Separate stand-alone study.
PT = Prothrombin time; FXa = Coagulation factor Xa; AUC = Area under the plasma concentration-time curve; AUEC = Area under the effect-time curve Hepatic Impairment Anti-Factor Xa activity was similar in adult subjects with normal hepatic function and in mild hepatic impairment (Child-Pugh A class). There is no clear understanding of the impact of hepatic impairment beyond this degree on the coagulation cascade and its relationship to efficacy and safety.
12.3Pharmacokinetics Absorption The absolute bioavailability of rivaroxaban is dose-dependent. For the 2.5 mg and 10 mg dose, it is estimated to be 80% to 100% and is not affected by food. XARELTO 2.5 mg and 10 mg tablets can be taken with or without food.
The maximum concentrations (C max ) of rivaroxaban appear 2 to 4 hours after tablet intake. The pharmacokinetics of rivaroxaban were not affected by drugs altering gastric pH. Coadministration of rivaroxaban (30 mg single dose) with the H 2 -receptor antagonist ranitidine (150 mg twice daily), the antacid aluminum hydroxide/magnesium hydroxide (10 mL) or rivaroxaban (20 mg single dose) with the PPI omeprazole (40 mg once daily) did not show an effect on the bioavailability and exposure of rivaroxaban (see Figure 3).
Absorption of rivaroxaban is dependent on the site of drug release in the GI tract. A 29% and 56% decrease in AUC and C max compared to tablet was reported when rivaroxaban granulate is released in the proximal small intestine. Exposure is further reduced when drug is released in the distal small intestine, or ascending colon.
Avoid administration of rivaroxaban distal to the stomach which can result in reduced absorption and related drug exposure. In a study with 44 healthy subjects, both mean AUC and C max values for 20 mg rivaroxaban administered orally as a crushed tablet mixed in applesauce were comparable to that after the whole tablet. However, for the crushed tablet suspended in water and administered via an NG tube followed by a liquid meal, only mean AUC was comparable to that after the whole tablet, and C max was 18% lower.
Distribution Protein binding of rivaroxaban in human plasma is approximately 92% to 95%, with albumin being the main binding component. The steady-state volume of distribution in healthy subjects is approximately 50 L. Metabolism Approximately 51% of an orally administered [ 14 C]-rivaroxaban dose was recovered as inactive metabolites in…
