Abdominal Surgery: In patients undergoing abdominal surgery who are at risk for thromboembolic complications, the recommended dose of Enoxaparin Sodium Injection is 40 mg once a day administered by SC injection with the initial dose given 2 hours prior to surgery. The usual duration of administration is 7 to 10 days; up to 12 days administration has been administered in clinical trials.

Hip or Knee Replacement Surgery: In patients undergoing hip or knee replacement surgery, the recommended dose of Enoxaparin Sodium Injection is 30 mg every 12 hours administered by SC injection. Provided that hemostasis has been established, the initial dose should be given 12 to 24 hours after surgery. For hip replacement surgery, a dose of 40 mg once a day SC, given initially 12 (±3) hours prior to surgery, may be considered. Following the initial phase of thromboprophylaxis in hip replacement surgery patients, it is recommended that continued prophylaxis with Enoxaparin Sodium Injection 40 mg once a day be administered by SC injection for 3 weeks. The usual duration of administration is 7 to 10 days; up to 14 days administration has been administered in clinical trials.

Medical Patients During Acute Illness: In medical patients at risk for thromboembolic complications due to severely restricted mobility during acute illness, the recommended dose of Enoxaparin Sodium Injection is 40 mg once a day administered by SC injection. The usual duration of administration is 6 to 11 days; up to 14 days of Enoxaparin Sodium Injection has been administered in the controlled clinical trial.

Treatment of Deep Vein Thrombosis with or without Pulmonary Embolism: In outpatient treatment, patients with acute deep vein thrombosis without pulmonary embolism who can be treated at home, the recommended dose of Enoxaparin Sodium Injection is 1 mg/kg every 12 hours administered SC. In inpatient (hospital) treatment, patients with acute deep vein thrombosis with pulmonary embolism or patients with acute deep vein thrombosis without pulmonary embolism (who are not candidates for outpatient treatment), the recommended dose of Enoxaparin Sodium Injection is 1 mg/kg every 12 hours administered SC or 1.5 mg/kg once a day administered SC at the same time every day. In both outpatient and inpatient (hospital) treatments, warfarin sodium therapy should be initiated when appropriate (usually within 72 hours of Enoxaparin Sodium Injection). Enoxaparin Sodium Injection should be continued for a minimum of 5 days and until a therapeutic oral anticoagulant effect has been achieved (International Normalization Ratio 2.0 to 3.0). The average duration of administration is 7 days; up to 17 days of Enoxaparin Sodium Injection administration has been administered in controlled clinical trials.

Unstable Angina and Non-Q-Wave Myocardial Infarction: In patients with unstable angina or non-Q-wave myocardial infarction, the recommended dose of Enoxaparin Sodium Injection is 1 mg/kg administered SC every 12 hours in conjunction with oral aspirin therapy (100 to 325 mg once daily). Treatment with Enoxaparin Sodium Injection should be prescribed for a minimum of 2 days and continued until clinical stabilization. The usual duration of treatment is 2 to 8 days; up to 12.5 days of Enoxaparin Sodium Injection has been administered in clinical trials [see Warnings and Precautions (5.2) and Clinical Studies (14.5)].

Treatment of Acute ST-Segment Elevation Myocardial Infarction:

In patients with acute ST-segment elevation myocardial infarction, the recommended dose of Enoxaparin Sodium Injection is a single IV bolus of 30 mg plus a 1 mg/kg SC dose followed by 1 mg/kg administered SC every 12 hours (maximum 100 mg for the first two doses only, followed by 1 mg/kg dosing for the remaining doses). Dosage adjustments are recommended in patients ≥75 years of age [see Dosage and Administration (2.3)]. All patients should receive aspirin as soon as they are identified as having STEMI and maintained with 75 to 325 mg once daily unless contraindicated.

When administered in conjunction with a thrombolytic (fibrin-specific or non-fibrin specific), Enoxaparin Sodium Injection should be given between 15 minutes before and 30 minutes after the start of fibrinolytic therapy. In the pivotal clinical study, the Enoxaparin Sodium Injection treatment duration was 8 days or until hospital discharge, whichever came first. An optimal duration of treatment is not known, but it is likely to be longer than 8 days.

For patients managed with percutaneous coronary intervention (PCI): If the last Enoxaparin Sodium Injection SC administration was given less than 8 hours before balloon inflation, no additional dosing is needed. If the last Enoxaparin Sodium Injection SC administration was given more than 8 hours before balloon inflation, an IV bolus of 0.3 mg/kg of Enoxaparin Sodium Injection should be administered [see Warnings and Precautions (5.2)].
