Adults 1) Reduction in the risk of stroke and systemic embolism in patients with nonvalvular atrial fibrillation The recommended dose of this medicine is 20 mg once daily. The recommended dose for patients with moderate renal impairment (creatinine clearance 30-49 mL/min) is 15 mg once daily. The maximum daily dose of this medicine is 20 mg. There is limited experience with concomitant administration of rivaroxaban 15mg once daily [10mg once daily for patients with moderate renal impairment (creatinine clearance 30-49 mL/min)] and a P2Y12 inhibitor for up to 12 months in patients with nonvalvular atrial fibrillation who have undergone percutaneous coronary intervention (PCI) with stent placement. (See '12. Clinical Trial Information') 2) Treatment of deep vein thrombosis and pulmonary embolism / Reduction in the risk of recurrence of deep vein thrombosis and pulmonary embolism The recommended initial dose of this medicine for the treatment of acute deep vein thrombosis and pulmonary embolism is 15 mg twice daily for the first 3 weeks. Thereafter, the recommended maintenance dose for the treatment of deep vein thrombosis and pulmonary embolism and the recommended dose for reducing the risk of recurrence are 20 mg once daily. After completing treatment (at least 6 months) for deep vein thrombosis or pulmonary embolism, the recommended dose for extended treatment to reduce the risk of recurrence is 10mg once daily. The duration and dose of treatment should be determined after an individual assessment of the risk of recurrence of deep vein thrombosis and pulmonary embolism relative to the risk of bleeding. Treatment period / Frequency of administration / Total daily dose Treatment of deep vein thrombosis or pulmonary embolism and reduction in the risk of recurrence Days 1-21 / 15mg twice daily / 30mg From day 22 / 20mg once daily / 20mg Reduction in the risk of recurrence of deep vein thrombosis or pulmonary embolism After at least 6 months of treatment / 10mg once daily / 10mg The maximum daily dose of this medicine is 30 mg during the first 3 weeks of treatment and 20 mg during the remainder of the treatment period. 3) Prevention of venous thromboembolism in adult patients undergoing major orthopedic surgery of the lower limbs (knee or hip replacement) The recommended dose of this medicine is 10 mg once daily. The initial dose should be started 6~10 hours after surgery, once hemostasis has been established. The duration of treatment depends on each patient's risk of venous thromboembolism according to the type of surgery; a treatment duration of 5 weeks is recommended for patients undergoing hip replacement and 2 weeks for patients undergoing knee replacement. 4) If you forget to take this medicine If you forget to take this medicine, take the missed dose as follows. ① Patients taking 15 mg twice daily: Take this medicine immediately; in this case, two 15 mg tablets may be taken at one time. From the following day, continue taking 15 mg twice daily. ② Patients taking 10, 15, or 20 mg once daily: Take the missed dose immediately. From the following day, continue taking 1 tablet once daily. The daily dose must not be doubled to make up for a missed dose. 2. Switching medications 1) Switching from a vitamin K antagonist to this medicine ① Reduction in the risk of stroke and systemic embolism in patients with nonvalvular atrial fibrillation Discontinue vitamin K antagonist therapy and start taking this medicine when the international normalized ratio (INR, International Normalized Ratio) is ≤ 3.0. ② Treatment of deep vein thrombosis and pulmonary embolism / Reduction in the risk of recurrence of deep vein thrombosis and pulmonary embolism Discontinue vitamin K antagonist therapy and start taking this medicine when the INR is ≤ 2.5. Regardless of the dose, the INR value will be falsely elevated after taking this medicine. INR should not be used because it is not suitable for measuring the anticoagulant activity of this medicine. 2) Switching from this medicine to a vitamin K antagonist Inadequate anticoagulation may occur while switching from this medicine to a vitamin K antagonist. Adequate anticoagulation should be maintained continuously while switching to another anticoagulant. Note that this medicine may affect the increase in INR. Patients switching from this medicine to a vitamin K antagonist should receive both medicines until the INR is ≥2.0. During the first 2 days after switching, administer the standard dose of the vitamin K antagonist, and thereafter administer the dose based on INR testing. However, in patients receiving this medicine together with a vitamin K antagonist, INR should not be tested until 24 hours after taking this medicine. Once this medicine is discontinued, INR may be tested 24 hours after the last dose. 3) Switching from a parenteral anticoagulant to this medicine For patients receiving a parenteral anticoagulant, start this medicine 0~2 hours before the next scheduled dose of the parenteral agent (e.g., low-molecular-weight heparin), or when a continuously administered parenteral agent (e.g., intravenous unfractionated heparin) is discontinued. 4) Switching from this medicine to a parenteral anticoagulant Discontinue this medicine and start the parenteral anticoagulant at the time the next dose of this medicine would have been due. 3. Patients with renal impairment No dose adjustment is required in patients with mild renal impairment with creatinine clearance 50-80 mL/min. Limited clinical experience in patients with severe renal impairment (creatinine clearance 15-29 mL/min) indicates that blood concentrations of this medicine increased significantly; therefore, administer this medicine with caution. Administration of this medicine is not recommended in patients with severe renal impairment with creatinine clearance less than 15 mL/min because there is no clinical experience in these patients. 1) Reduction in the risk of stroke and systemic embolism in patients with nonvalvular atrial fibrillation The recommended dose for patients with moderate renal impairment (creatinine clearance 30-49 mL/min) and severe renal impairment (creatinine clearance 15-29 mL/min) is 15 mg once daily. 2) Treatment of deep vein thrombosis and pulmonary embolism / Reduction in the risk of recurrence of deep vein thrombosis and pulmonary embolism / Prevention of venous thromboembolism in adult patients undergoing major orthopedic surgery of the lower limbs (knee or hip replacement) No dose adjustment is required in patients with moderate renal impairment (creatinine clearance 30-49 mL/min). 4. Patients with hepatic impairment Avoid administering this medicine to patients with liver disease associated with coagulopathy and patients with moderate (Child Pugh B) or severe (Child Pugh C) hepatic impairment. Increased exposure to this medicine and an increased risk of bleeding may occur in these patients. 5. Patients who are unable to swallow tablets, Immediately before use, this medicine may be crushed and mixed with water or a beverage such as applesauce for oral administration. This medicine may also be crushed and administered with a small amount of water through a feeding tube. Before administering this medicine through a feeding tube, confirm that the tube is properly positioned, and flush the tube with water after administration.

This medication is an anticoagulant used to prevent or treat thrombus formation by inhibiting blood coagulation. During treatment, there is a risk of bleeding, so careful monitoring for bleeding signs is required. If severe bleeding occurs, discontinue the medication immediately and consult a healthcare professional. This drug should not be administered to patients with certain conditions or illnesses, such as patients with severe bleeding, severely impaired liver function, women who are pregnant or breastfeeding, and those with lactose intolerance. Additionally, patients with a recent history of diseases or surgeries with a high risk of bleeding should be cautious. Patients with impaired renal function or those taking other anticoagulants or medications that increase the risk of bleeding should also use this medication carefully. This drug may have various side effects, with bleeding being the most significant, along with reports of anemia, gastrointestinal symptoms, skin rashes, and liver function abnormalities. If severe skin rashes or mucosal ulcers develop, consult a physician immediately. This medication interacts with many other drugs, so inform your doctor or pharmacist of any current medications. Women who are pregnant or breastfeeding should not take this drug, and women of childbearing potential should ensure contraception during treatment. Elderly patients may also have an increased risk of bleeding and should be cautious, though specific dose adjustments are generally not required. In case of overdose, the risk of bleeding may significantly increase, requiring immediate medical attention. When driving or operating machinery, be cautious as side effects, such as drowsiness or fainting, may occur. If surgical or invasive procedures are planned, this medication should be discontinued at least 12 to 24 hours in advance and resumed post-procedure according to medical advice. If bleeding symptoms or adverse reactions occur while taking this drug, consult a healthcare professional immediately, and regular blood tests may help assess bleeding risk.
