Black Box Warning

SPINAL/EPIDURAL HEMATOMA
See full prescribing information for complete Boxed Warning.
* 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:

Overview

Enoxaparin is an anticoagulant and low molecular weight heparin that is FDA approved for the treatment of acute deep vein thrombosis, acute ST-segment elevation myocardial infarction and prophylaxis of deep vein thrombosis and ischemic complications of unstable angina and non-Q-wave myocardial infarction. There is a Black Box Warning for this drug as shown here. Common adverse reactions include diarrhea, nausea, anemia, major bleeding, thrombocytopenia, increased liver function test, and fever.

  • For inpatient: 1 mg/kg SC q12h or 1.5 mg/kg SC q24h
  • Warfarin therapy should be initiated when appropriate (usually within 72 hours of enoxaparin injection).
  • Duration of administration: 7 days (maximum: 17 days)
  • Enoxaparin should be continued for a minimum of 5 days and until a therapeutic oral anticoagulant effect has been achieved (INR 2.0–3.0).

Prophylaxis of Ischemic Complications of Unstable Angina and Non-Q-Wave Myocardial Infarction

  • Dosing information
  • Recommended dose: 1 mg/kg SC q12h (in conjunction with aspirin 100–325 mg PO qd)

Renal Impairment

Although no dose adjustment is recommended in patients with moderate (creatinine clearance 30–50 mL/min) and mild (creatinine clearance 50–80 mL/min) renal impairment, all such patients should be observed carefully for signs and symptoms of bleeding.

The recommended prophylaxis and treatment dosage regimens for patients with severe renal impairment (creatinine clearance <30 mL/min) are described in Table 1.

Contraindications

Warnings

SPINAL/EPIDURAL HEMATOMA
See full prescribing information for complete Boxed Warning.
* 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:

Cases of epidural or spinal hemorrhage and subsequent hematomas have been reported with the use of Lovenox and epidural or spinal anesthesia/analgesia or spinal puncture procedures, resulting in long-term or permanent paralysis. The risk of these events is higher with the use of post-operative indwelling epidural catheters, with the concomitant use of additional drugs affecting hemostasis such as NSAIDs, with traumatic or repeated epidural or spinal puncture, or in patients with a history of spinal surgery or spinal deformity.
