WARNING: SPINAL/EPIDURAL HEMATOMAS Epidural or spinal hematomas may occur in patients who are anticoagulated with low molecular weight heparins (LMWH) or heparinoids and 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 enoxaparin sodium injection and neuraxial procedures is not known Monitor patients frequently for signs and symptoms of neurological impairment. If neurological compromise is noted, urgent treatment is necessary. Consider the benefits and risks before neuraxial intervention in patients anticoagulated or to be anticoagulated for thromboprophylaxis [see Warnings and Precautions (5.1) and Drug Interactions (7) ] .

Adult Dosing
General dosing
See full prescribing information for dosing and administration information. 2.1 Pretreatment Evaluation Evaluate all patients for a bleeding disorder before starting enoxaparin sodium treatment, unless treatment is urgently needed. 2.2 Adult Dosage Abdominal Surgery The recommended dose of enoxaparin sodium is 40 mg by subcutaneous injection once a day (with the initial dose given 2 hours prior to surgery) in patients undergoing abdominal surgery who are at risk for thromboembolic complications. The usual duration of administration is 7 to 10 days . Hip or Knee Replacement Surgery The recommended dose of enoxaparin sodium is 30 mg every 12 hours administered by subcutaneous injection in patients undergoing hip or knee replacement surgery. Administer the initial dose 12 to 24 hours after surgery, provided that hemostasis has been established. The usual duration of administration is 7 to 10 days . A dose of enoxaparin sodium of 40 mg once a day subcutaneously may be considered for hip replacement surgery for up to 3 weeks. Administer the initial dose 12 (±3) hours prior to surgery.
Geriatric Dosing
General dosing
Recommended Dosage for Geriatric Patients with Acute ST-Segment Elevation Myocardial Infarction For treatment of acute ST-segment elevation myocardial infarction in geriatric patients ≥75 years of age, do not use an initial intravenous bolus . Initiate dosing with 0.75 mg/kg subcutaneously every 12 hours (maximum 75 mg for the first two doses only, followed by 0.75 mg/kg dosing for the remaining doses) . No dose adjustment is necessary for other indications in geriatric patients unless kidney function is impaired [see] . 2.5 Administration Do not administer enoxaparin sodium injection by intramuscular injection. Administer enoxaparin sodium by subcutaneous injection only. Enoxaparin sodium injection is a clear, colorless to pale yellow sterile solution, and as with other parenteral drug products, should be inspected visually for particulate matter and discoloration prior to administration. Patients may self-inject by the subcutaneous route of administration only after their physicians determine that it is appropriate and with medical follow-up, as necessary.
