| INDICATIONS AND USAGE
XARELTO is a factor Xa inhibitor indicated:
(1) to reduce the risk of stroke and systemic embolism in patients with nonvalvular atrial fibrillation.
(2) for the prophylaxis of deep vein thrombosis (DVT), which may lead to pulmonary embolism (PE) in patients undergoing knee or hip replacement surgery
USE IN SPECIFIC POPULATIONS
Nursing mothers: discontinue drug or discontinue nursing
Prophylaxis of DVT: Avoid use in patients with severe impairment (CrCl <30 mL/min).
Use with caution in moderate impairment (CrCl 30 to <50 mL/min)
DOSAGE AND ADMINISTRATION
2.1 Nonvalvular Atrial Fibrillation
For patients with creatinine clearance (CrCl) >50 mL/min, the recommended dose of XARELTO is 20 mg taken orally once daily with the evening meal. For patients with CrCl 15 to 50 mL/min, the recommended dose is 15 mg once daily with the evening meal [see package insert for Use in Specific Populations (8.7)].
Switching from or to Warfarin - When switching patients from warfarin to XARELTO, discontinue warfarin and start XARELTO as soon as the International Normalized Ratio (INR) is below 3.0 to avoid periods of inadequate anticoagulation.
No clinical trial data are available to guide converting patients from XARELTO to warfarin. XARELTO affects INR, so INR measurements made during co-administration 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.
Switching from or to Anticoagulants other than Warfarin - For patients currently receiving an anticoagulant other than warfarin, start XARELTO 0 to 2 hours prior to the next scheduled evening 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.
For 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.
2.2 Prophylaxis of Deep Vein Thrombosis
The recommended dose of XARELTO is 10 mg taken orally once daily with or without food. The initial dose should be taken at least 6 to 10 hours after surgery once hemostasis has been established.
-For patients undergoing hip replacement surgery, treatment duration of 35 days is recommended.
-For patients undergoing knee replacement surgery, treatment duration of 12 days is recommended.
2.3 General Dosing Instructions
No clinical data are available for 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 [see Use in Specific Populations (8.8)].
Nonvalvular Atrial Fibrillation:
Avoid the use of XARELTO in patients with CrCl <15 mL/min. Periodically assess renal function as clinically indicated (i.e., more frequently in situations in which renal function may decline) and adjust therapy accordingly. Discontinue XARELTO in patients who develop acute renal failure while on XARELTO [see Use in Specific Populations (8.7)].
Prophylaxis of Deep Vein Thrombosis:
Avoid the use of XARELTO in patients with severe renal impairment (CrCl <30 mL/min) due to an expected increase in rivaroxaban exposure and pharmacodynamic effects in this patient population. Observe closely and promptly evaluate any signs or symptoms of blood loss in patients with moderate renal impairment (CrCl 30 to 50 mL/min). Patients who develop acute renal failure while on XARELTO should discontinue the treatment [see Use in Specific Populations (8.7)].
Surgery and Intervention:
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. 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. If oral medication cannot be taken after surgical intervention, consider administering a parenteral anticoagulant.
If a dose of XARELTO is not taken at the scheduled time, administer the dose as soon as possible on the same day.
Use with P-gp and Strong CYP3A4 Inhibitors or Inducers:
Avoid concomitant use of XARELTO with combined P-gp and strong CYP3A4 inhibitors (e.g., ketoconazole, itraconazole, lopinavir/ritonavir, ritonavir, indinavir/ritonavir, and conivaptan) [see Drug Interactions (7.1)].
Avoid concomitant use of XARELTO with drugs that are combined P-gp and strong CYP3A4 inducers (e.g., carbamazepine, phenytoin, rifampin, St. John's wort)
