Preoperative start (day of surgery):
-2500 international units subcutaneously within 2 hours before surgery

Use: Prophylaxis of deep vein thrombosis (DVT), which may lead to pulmonary embolism (PE) in patients undergoing hip replacement surgery.

Usual Adult Dose for Deep Vein Thrombosis Prophylaxis after Abdominal Surgery

Moderate risk of thromboembolic complications: 2500 international units subcutaneously once a day, starting 1 to 2 hours prior to surgery and repeated once a day postoperatively.

High risk of thromboembolic complications (e.g., malignant disorder): 5000 international units subcutaneously the evening before surgery and once a day postoperatively OR 2500 international units subcutaneously 1 to 2 hours before surgery followed 2500 international units subcutaneously 12 hours later and then 5000 international units subcutaneously once a day postoperatively.

Duration of therapy: Usually 5 to 10 days

Use: Prophylaxis of DVT, which may lead to PE in patients undergoing abdominal surgery who are at risk for thromboembolic complications.

Usual Adult Dose for Deep Vein Thrombosis - Prophylaxis

5000 international units subcutaneously once a day

Duration of therapy: Usually 12 to 14 days

Use: Prophylaxis of DVT, which may lead to PE in medical patients who are at risk for thromboembolic complications due to severely restricted mobility during acute illness.

Usual Adult Dose for Venous Thromboembolism

200 international units/kg total body weight subcutaneously once a day for the first month; 150 international units/kg total body weight subcutaneously once a day for months 2 through 6

Maximum dose: 18,000 international units/day

Duration of therapy: 6 months

Comments:
-In patients with CrCl less than 30 mL/min, monitor anti-Xa levels to determine dose (target anti-Xa range is 0.5 to 1.5 international units/mL); sample 4 to 6 hours after dosing and only after the patient has received 3 to 4 doses.

Dose Adjustments

Cancer Patients with Acute Symptomatic Venous Thromboembolism (VTE):
-Platelets 50,000 to 100,000/mm3: Reduce dose by 2500 international units until platelets increase to 100,000/mm3 or greater
-Platelets less than 50,000/mm3: Discontinue therapy until platelets increase above 50,000/mm3

Precautions

US BOXED WARNINGS:
-SPINAL/EPIDURAL HEMATOMAS: Epidural or spinal hematomas, which could lead to long-term or permanent paralysis, may occur in patients who are anticoagulated with low molecular weight heparins (LMWH) or heparinoids and are receiving neuraxial anesthesia or spinal puncture. Factors that can increase the risk of developing epidural or spinal hematomas in these patients include indwelling epidural catheters, concomitant use of other drugs that affect hemostasis (e.g., non-steroidal anti-inflammatory drugs [NSAIDs], platelet inhibitors, and other anticoagulants), a history of traumatic or repeated epidural or spinal punctures, and a history of spinal deformity or surgery. Optimal timing between the administration of this drug and neuraxial procedures remains unknown. 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.

Safety and efficacy have not been established in patients younger than 18 years.

Consult WARNINGS section for additional precautions.
