Dosage Form Body Weight 1 mg XARELTO = 1 mL Suspension Dosage Total Daily Dose All doses should be taken with feeding or with food since exposures match that of 20 mg daily dose in adults. Once a Day Once a day: approximately 24 hours apart; 2 times a day: approximately 12 hours apart; 3 times a day: approximately 8 hours apart 2 Times a Day 3 Times a Day Oral Suspension Only 2.6 kg to 2.9 kg 0.8 mg 2.4 mg 3 kg to 3.9 kg 0.9 mg 2.7 mg 4 kg to 4.9 kg 1.4 mg 4.2 mg 5 kg to 6.9 kg 1.6 mg 4.8 mg 7 kg to 7.9 kg 1.8 mg 5.4 mg 8 kg to 8.9 kg 2.4 mg 7.2 mg 9 kg to 9.9 kg 2.8 mg 8.4 mg 10 kg to 11.9 kg 3 mg 9 mg 12 kg to 29.9 kg 5 mg 10 mg Oral Suspension or Tablets 30 kg to 49.9 kg 15 mg 15 mg ≥50 kg 20 mg 20 mg Dosing of XARELTO was not studied and therefore dosing cannot be reliably determined in the following patient populations. 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 <2 years old with catheter-related thrombosis): Therapy with XARELTO 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 <2 years old with catheter-related thrombosis: Therapy with XARELTO 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. The benefit of continued therapy beyond 1 month should be assessed on an individual basis taking into account the risk for recurrent thrombosis versus the potential risk of bleeding. Thromboprophylaxis in Pediatric Patients with Congenital Heart Disease after the Fontan Procedure Table 3: Recommended Dosage for Thromboprophylaxis in Pediatric Patients with Congenital Heart Disease Dosage Form Body Weight 1 mg XARELTO = 1 mL Suspension Dosage Total Daily Dose All doses can be taken with or without food since exposures match that of 10 mg daily dose in adults.

For thromboprophylaxis after Fontan procedure, the dose can be taken with or without food. Vomit or Spit up: If the patient vomits or spits up the dose within 30 minutes after receiving the dose, a new dose should be given. However, if the patient vomits more than 30 minutes after the dose is taken, the dose should not be re-administered and the next dose should be taken as scheduled. If the patient vomits or spits up the dose repeatedly, the caregiver should contact the child's doctor right away. Tablets: XARELTO tablet must not be split in an attempt to provide a fraction of a tablet dose. For children unable to swallow 10, 15, or 20 mg whole tablets, XARELTO oral suspension should be used. XARELTO 2.5 mg tablets are not recommended for use in pediatric patients . Use in Renal Impairment in Pediatric Patients Patients 1 Year of Age or Older Mild renal impairment (eGFR: 50 to ≤ 80 mL/min/1.73 m 2 ): No dose adjustment is required. Moderate or severe renal impairment (eGFR: <50 mL/min/1.73 m 2 ): avoid use, as limited clinical data are available. Estimated glomerular filtration rate (eGFR) can be done using the updated Schwartz formula, eGFR (Schwartz) = (0.413 × height in cm)/serum creatinine in mg/dL, if serum creatinine (SCr) is measured by an enzymatic creatinine method that has been calibrated to be traceable to isotope dilution mass spectrometry (IDMS). If SCr is measured with routine methods that have not been recalibrated to be traceable to IDMS (e.g., the traditional Jaffé reaction), the eGFR should be obtained from the original Schwartz formula: eGFR (mL/min/1.73 m 2 ) = k * height (cm)/SCr (mg/dL), where k is proportionality constant: k = 0.55 in children 1 year to 13 years k = 0.55 in girls > 13 and < 18 years k = 0.70 in boys > 13 and < 18 years Patients Less than 1 Year of Age Determine renal function using serum creatinine. Avoid use of XARELTO in pediatric patients younger than 1 year with serum creatinine results above 97.5 th percentile, as no clinical data are available. Table 4: Reference Values of Serum Creatinine in Pediatric Patients <1 Year of Age Age 97.5 th Percentile of Creatinine (mg/dL) 97.5 th Percentile of Creatinine (µmol/L) Week 2 0.52 46 Week 3 0.46 41 Week 4 0.42 37 Month 2 0.37 33 Month 3 0.34 30 Month 4–6 0.34 30 Month 7–9 0.34 30 Month 10–12 0.36 32 2.3 Switching to and from XARELTO Switching from Warfarin to XARELTO - When switching patients from warfarin to XARELTO, discontinue warfarin and start XARELTO as soon as the International Normalized Ratio (INR) is below 3.0 in adults and below 2.5 in pediatric patients to avoid periods of inadequate anticoagulation. Switching from XARELTO to Warfarin – Adults: No clinical trial data are available to guide converting patients from XARELTO to warfarin. XARELTO affects INR, so INR measurements made during coadministration with warfarin may not be useful for determining the appropriate dose of warfarin. One approach is to discontinue XARELTO and begin both a parenteral anticoagulant and warfarin at the time the next dose of XARELTO would have been taken. Pediatric Patients: To ensure adequate anticoagulation during the transition from XARELTO to warfarin, continue XARELTO for at least 2 days after the first dose of warfarin. After 2 days of co-administration, an INR should be obtained prior to the next scheduled dose of XARELTO. Co-administration of XARELTO and warfarin is advised to continue until the INR is ≥ 2.0. Once XARELTO is discontinued, INR testing may be done reliably 24 hours after the last dose. Switching from XARELTO to Anticoagulants other than Warfarin - For adult and pediatric patients currently taking XARELTO and transitioning to an anticoagulant with rapid onset, discontinue XARELTO and give the first dose of the other anticoagulant (oral or parenteral) at the time that the next XARELTO dose would have been taken . Switching from Anticoagulants other than Warfarin to XARELTO - For adult and pediatric patients currently receiving an anticoagulant other than warfarin, start XARELTO 0 to 2 hours prior to the next scheduled administration of the drug (e.g., low molecular weight heparin or non-warfarin oral anticoagulant) and omit administration of the other anticoagulant. For unfractionated heparin being administered by continuous infusion, stop the infusion and start XARELTO at the same time

Discontinuation for Surgery and other Interventions If anticoagulation must be discontinued to reduce the risk of bleeding with surgical or other procedures, XARELTO should be stopped at least 24 hours before the procedure to reduce the risk of bleeding . In deciding whether a procedure should be delayed until 24 hours after the last dose of XARELTO, the increased risk of bleeding should be weighed against the urgency of intervention. XARELTO should be restarted after the surgical or other procedures as soon as adequate hemostasis has been established, noting that the time to onset of therapeutic effect is short . If oral medication cannot be taken during or after surgical intervention, consider administering a parenteral anticoagulant

Missed Dose Adults For patients receiving 2.5 mg twice daily: if a dose is missed, the patient should take a single 2.5 mg XARELTO dose as recommended at the next scheduled time. For patients receiving 15 mg twice daily: The patient should take XARELTO immediately to ensure intake of 30 mg XARELTO per day. Two 15 mg tablets may be taken at once. For patients receiving 20 mg, 15 mg or 10 mg once daily: The patient should take the missed XARELTO dose immediately. The dose should not be doubled within the same day to make up for a missed dose. Pediatric Patients If XARELTO is taken once a day, the patient should take the missed dose as soon as possible once it is noticed, but only on the same day. If this is not possible, the patient should skip the dose and continue with the next dose as prescribed. The patient should not take two doses to make up for a missed dose. If XARELTO is taken two times a day, the patient should take the missed morning dose as soon as possible once it is noticed. A missed morning dose may be taken together with the evening dose. A missed evening dose can only be taken in the same evening. If XARELTO is taken three times a day, if a dose is missed, the patient should skip the missed dose and go back to the regular dosing schedule at the usual time without compensating for the missed dose. On the following day, the patient should continue with their regular regimen

Administration Options For adult patients who are unable to swallow whole tablets, XARELTO tablets (all strengths) may be crushed and mixed with applesauce immediately prior to use and administered orally. After the administration of a crushed XARELTO 15 mg or 20 mg tablet, the dose should be immediately followed by food. Administration with food is not required for the 2.5 mg or 10 mg tablets . Administration of XARELTO tablets via nasogastric (NG) tube or gastric feeding tube: After confirming gastric placement of the tube, XARELTO tablets (all strengths) may be crushed and suspended in 50 mL of water and administered via an NG tube or gastric feeding tube. Since rivaroxaban absorption is dependent on the site of drug release, avoid administration of XARELTO distal to the stomach which can result in reduced absorption and thereby, reduced drug exposure. After the administration of a crushed XARELTO 15 mg or 20 mg tablet, the dose should then be immediately followed by enteral feeding. Enteral feeding is not required following administration of the 2.5 mg or 10 mg tablets . Crushed XARELTO tablets (all strengths) are stable in water and in applesauce for up to 4 hours. An in vitro compatibility study indicated that there is no adsorption of rivaroxaban from a water suspension of a crushed XARELTO tablet to PVC or silicone nasogastric (NG) tubing. Administration of XARELTO suspension via NG tube or gastric feeding tube : XARELTO oral suspension may be given through NG or gastric feeding tube. After the administration, flush the feeding tube with water. For the treatment or reduction in risk of recurrent VTE in pediatric patients, the dose should then be immediately followed by enteral feeding to increase absorption. For the thromboprophylaxis in pediatric patients with congenital heart disease who have undergone the Fontan procedure, the dose does not require to be followed by enteral feeding. An in vitro compatibility study indicated that XARELTO suspension can be used with PVC, polyurethane or silicone NG tubing

Preparation Instructions for Pharmacy of XARELTO for Oral Suspension Do not add flavor as product is already flavored (sweet and creamy). Reconstitute before dispensing: Tap the bottle until all granules flow freely. Add 150 mL of purified water for reconstitution. Shake for 60 seconds. Check that all granules are wetted and the suspension is uniform. Push the adaptor into bottleneck and recap bottle. The suspension must be used within 60 days. Write the "Discard after" date on the bottle and carton. Dispensing Instructions: Dispense in the original bottle. Dispense the bottle upright with the syringes provided in the original carton. Store reconstituted suspension at room temperature between 20 °C to 25 °C (68 °F to 77 °F); excursions permitted between 15 °C to 30 °C (59 °F to 86 °F). Do not freeze. It is recommended the pharmacist counsel the caregiver on proper use. Alert the patient or caregiver to read the Medication Guide and Instructions for Use.

Risk of bleeding: XARELTO can cause serious and fatal bleeding Pregnancy-related hemorrhage: Use XARELTO with caution in pregnant women due to the potential for obstetric hemorrhage and/or emergent delivery Prosthetic heart valves: XARELTO use not recommended Increased Risk of Thrombosis in Patients with Triple Positive Antiphospholipid Syndrome: XARELTO use not recommended 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

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 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 XARELTO 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) , 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 . 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 XARELTO 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. XARELTO is not for use for primary VTE prophylaxis in these hospitalized, acutely ill medical patients at high risk of bleeding. Reversal of Anticoagulant Effect A specific agent to reverse the anti-factor Xa activity of rivaroxaban is not available. Because of high plasma protein binding, rivaroxaban is not dialyzable . 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

Spinal/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 can result in long-term or permanent paralysis . To reduce the potential risk of bleeding associated with the concurrent use of XARELTO and epidural or spinal anesthesia/analgesia or spinal puncture, consider the pharmacokinetic profile of XARELTO . Placement or removal of an epidural catheter or lumbar puncture is best performed when the anticoagulant effect of XARELTO is low; however, the exact timing to reach a sufficiently low anticoagulant effect in each patient is not known. An indwelling epidural or intrathecal catheter should not be removed before at least 2 half-lives have elapsed (i.e., 18 hours in young patients aged 20 to 45 years and 26 hours in elderly patients aged 60 to 76 years), after the last administration of XARELTO . The next XARELTO dose should not be administered earlier than 6 hours after the removal of the catheter. If traumatic puncture occurs, delay the administration of XARELTO for 24 hours. Should the physician decide to administer anticoagulation in the context of epidural or spinal anesthesia/analgesia or lumbar puncture, monitor frequently to detect any signs or symptoms of neurological impairment, such as midline back pain, sensory and motor deficits (numbness, tingling, or weakness in lower limbs), bowel and/or bladder dysfunction. Instruct patients to immediately report if they experience any of the above signs or symptoms. If signs or symptoms of spinal hematoma are suspected, initiate urgent diagnosis and treatment including consideration for spinal cord decompression even though such treatment may not prevent or reverse neurological sequelae

Use in Patients with Renal Impairment Nonvalvular Atrial Fibrillation Periodically assess renal function as clinically indicated (i.e., more frequently in situations in which renal function may decline) and adjust therapy accordingly . Consider dose adjustment or discontinuation of XARELTO in patients who develop acute renal failure while on XARELTO . Treatment of Deep Vein Thrombosis (DVT), Pulmonary Embolism (PE), and Reduction in the Risk of Recurrence of DVT and of PE In patients with CrCl <30 mL/min, rivaroxaban exposure and pharmacodynamic effects are increased compared to patients with normal renal function. There are limited clinical data in patients with CrCl 15 to <30 mL/min; therefore, observe closely and promptly evaluate any signs or symptoms of blood loss in these patients. There are no clinical data in patients with CrCl <15 mL/min (including patients on dialysis); therefore, avoid the use of XARELTO in these patients. Discontinue XARELTO in patients who develop acute renal failure while on treatment . Prophylaxis of Deep Vein Thrombosis Following Hip or Knee Replacement Surgery In patients with CrCl <30 mL/min, rivaroxaban exposure and pharmacodynamic effects are increased compared to patients with normal renal function. There are limited clinical data in patients with CrCl 15 to <30 mL/min; therefore, observe closely and promptly evaluate any signs or symptoms of blood loss in these patients. There are no clinical data in patients with CrCl <15 mL/min (including patients on dialysis); therefore, avoid the use of XARELTO in these patients. Discontinue XARELTO in patients who develop acute renal failure while on treatment . Prophylaxis of Venous Thromboembolism in Acutely Ill Medical Patients at Risk for Thromboembolic Complications Not at High Risk of Bleeding In patients with CrCl <30 mL/min, rivaroxaban exposure and pharmacodynamic effects are increased compared to patients with normal renal function. There are limited clinical data in patients with CrCl 15 to <30 mL/min; therefore, observe closely and promptly evaluate any signs or symptoms of blood loss in these patients. There are no clinical data in patients with CrCl <15 mL/min (including patients on dialysis); therefore, avoid the use of XARELTO in these patients. Discontinue XARELTO in patients who develop acute renal failure while on treatment . Pediatric Patients There are limited clinical data in pediatric patients 1 year or older with moderate or severe renal impairment (eGFR <50 mL/min/1.73 m 2 ); therefore, avoid the use of XARELTO in these patients. There are no clinical data in pediatric patients younger than 1 year with serum creatinine results above 97.5 th percentile; therefore, avoid the use of XARELTO in these patients

Use in Patients with Hepatic Impairment No clinical data are available for adult patients with severe hepatic impairment. Avoid use of XARELTO in patients with moderate (Child-Pugh B) and severe (Child-Pugh C) hepatic impairment or with any hepatic disease associated with coagulopathy since drug exposure and bleeding risk may be increased . No clinical data are available in pediatric patients with hepatic impairment

Use with P-gp and Strong CYP3A Inhibitors or Inducers Avoid concomitant use of XARELTO with known combined P-gp and strong CYP3A inhibitors . Avoid concomitant use of XARELTO with drugs that are known combined P-gp and strong CYP3A inducers

Risk of Pregnancy-Related Hemorrhage In pregnant women, XARELTO should be used only if the potential benefit justifies the potential risk to the mother and fetus. XARELTO dosing in pregnancy has not been studied. The anticoagulant effect of XARELTO cannot be monitored with standard laboratory testing. Promptly evaluate any signs or symptoms suggesting blood loss (e.g., a drop in hemoglobin and/or hematocrit, hypotension, or fetal distress)

Patients with Prosthetic Heart Valves On the basis of the GALILEO study, use of XARELTO is not recommended in patients who have had transcatheter aortic valve replacement (TAVR) because patients randomized to XARELTO experienced higher rates of death and bleeding compared to those randomized to an anti-platelet regimen. The safety and efficacy of XARELTO have not been studied in patients with other prosthetic heart valves or other valve procedures. Use of XARELTO is not recommended in patients with prosthetic heart valves

Acute PE in Hemodynamically Unstable Patients or Patients Who Require Thrombolysis or Pulmonary Embolectomy Initiation of XARELTO is not recommended acutely as an alternative to unfractionated heparin in patients with pulmonary embolism who present with hemodynamic instability or who may receive thrombolysis or pulmonary embolectomy

Increased Risk of Thrombosis in Patients with Triple Positive Antiphospholipid Syndrome Direct-acting oral anticoagulants (DOACs), including XARELTO, are not recommended for use in patients with triple-positive antiphospholipid syndrome (APS). For patients with APS (especially those who are triple positive [positive for lupus anticoagulant, anticardiolipin, and anti-beta 2-glycoprotein I antibodies]), treatment with DOACs has been associated with increased rates of recurrent thrombotic events compared with vitamin K antagonist therapy.

Avoid combined P-gp and strong CYP3A inhibitors and inducers Anticoagulants: Avoid concomitant use 7.1 General Inhibition and Induction Properties Rivaroxaban is a substrate of CYP3A4/5, CYP2J2, and the P-gp and ATP-binding cassette G2 (ABCG2) transporters, the latter also known as breast cancer resistance protein (BCRP). 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

Drugs that Inhibit Cytochrome P450 3A Enzymes and Drug Transport Systems Interaction with Combined P-gp and Strong CYP3A Inhibitors Avoid concomitant administration of XARELTO with known combined P-gp and strong CYP3A inhibitors (e.g., ketoconazole and ritonavir) . Although clarithromycin is a combined P-gp and strong CYP3A inhibitor, pharmacokinetic data suggests that no precautions are necessary with concomitant administration with XARELTO as the change in exposure is unlikely to affect the bleeding risk . Interaction with Combined P-gp and Moderate CYP3A Inhibitors in Patients with Renal Impairment XARELTO should not be used in patients with CrCl 15 to <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

Drugs that Induce Cytochrome P450 3A Enzymes and Drug Transport Systems Avoid concomitant use of XARELTO with drugs that are combined P-gp and strong CYP3A inducers (e.g., carbamazepine, phenytoin, rifampin, St. John's wort)

Anticoagulants and NSAIDs/Aspirin Coadministration of enoxaparin, warfarin, aspirin, clopidogrel and chronic NSAID use may increase the risk of bleeding . Avoid concurrent use of XARELTO 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 .
