1 INDICATIONS AND USAGE Lovenox is a low molecular weight heparin (LMWH) indicated for: Prophylaxis of deep vein thrombosis (DVT) in abdominal surgery, hip replacement surgery, knee replacement surgery, or medical patients with severely restricted mobility during acute illness ( 1.1 ) Inpatient treatment of acute DVT with or without pulmonary embolism ( 1.2 ) Outpatient treatment of acute DVT without pulmonary embolism ( 1.2 ) Prophylaxis of ischemic complications of unstable angina and non–Q-wave myocardial infarction (MI) ( 1.3 ) Treatment of acute ST-segment elevation myocardial infarction (STEMI) managed medically or with subsequent percutaneous coronary intervention (PCI) ( 1.4 ) 1.1 Prophylaxis of Deep Vein Thrombosis Lovenox ® is indicated for the prophylaxis of deep vein thrombosis (DVT), which may lead to pulmonary embolism (PE): in patients undergoing abdominal surgery who are at risk for thromboembolic complications [see Clinical Studies (14.1) ] in patients undergoing hip replacement surgery, during and following hospitalization in patients undergoing knee replacement surgery in medical patients who are at risk for thromboembolic complications due to severely restricted mobility during acute illness 1.2 Treatment of Acute Deep Vein Thrombosis Lovenox is indicated for: the inpatient treatment of acute deep vein thrombosis with or without pulmonary embolism , when administered in conjunction with warfarin sodium the outpatient treatment of acute deep vein thrombosis without pulmonary embolism , when administered in conjunction with warfarin sodium 1.3 Prophylaxis of Ischemic Complications of Unstable Angina and Non–Q-Wave Myocardial Infarction Lovenox is indicated for the prophylaxis of ischemic complications of unstable angina and non–Q-wave myocardial infarction, when concurrently administered with aspirin. 1.4 Treatment of Acute ST-Segment Elevation Myocardial Infarction Lovenox, when administered concurrently with aspirin, has been shown to reduce the rate of the combined endpoint of recurrent myocardial infarction or death in patients with acute ST-segment elevation myocardial infarction (STEMI) receiving thrombolysis and being managed medically or with percutaneous coronary intervention (PCI).

2 DOSAGE AND ADMINISTRATION See full prescribing information for dosing and administration information. ( 2 ) 2.1 Pretreatment Evaluation Evaluate all patients for a bleeding disorder before starting Lovenox treatment, unless treatment is urgently needed. 2.2 Adult Dosage Abdominal Surgery The recommended dose of Lovenox 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 [see Clinical Studies (14.1) ] . Hip or Knee Replacement Surgery The recommended dose of Lovenox 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 [see Clinical Studies (14.2) ] . A dose of Lovenox 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. Medical Patients during Acute Illness The recommended dose of Lovenox is 40 mg once a day administered by subcutaneous injection for medical patients at risk for thromboembolic complications due to severely restricted mobility during acute illness. The usual duration of administration is 6 to 11 days [see Clinical Studies (14.3) ] . Treatment of Deep Vein Thrombosis with or without Pulmonary Embolism The recommended dose of Lovenox is 1 mg/kg every 12 hours administered subcutaneously in patients with acute deep vein thrombosis without pulmonary embolism, who can be treated at home in an outpatient setting. The recommended dose of Lovenox is 1 mg/kg every 12 hours administered subcutaneously or 1.5 mg/kg once a day administered subcutaneously at the same time every day for inpatient (hospital) treatment of 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). In both outpatient and inpatient (hospital) treatments, initiate warfarin sodium therapy when appropriate (usually within 72 hours of Lovenox). Continue Lovenox for a minimum of 5 days and until a therapeutic oral anticoagulant effect has been achieved (International Normalization Ratio 2 to 3). The average duration of administration is 7 days [see Clinical Studies (14.4) ] . Unstable Angina and Non–Q-Wave Myocardial Infarction The recommended dose of Lovenox is 1 mg/kg administered subcutaneously every 12 hours in conjunction with oral aspirin therapy (100 to 325 mg once daily) in patients with unstable angina or non–Q-wave myocardial infarction. Treat with Lovenox for a minimum of 2 days and continue until clinical stabilization. The usual duration of treatment is 2 to 8 days [see Warnings and Precautions (5.2) and Clinical Studies (14.5) ] . Treatment of Acute ST-Segment Elevation Myocardial Infarction The recommended dose of Lovenox is a single intravenous bolus of 30 mg plus a 1 mg/kg subcutaneous dose followed by 1 mg/kg administered subcutaneously every 12 hours (maximum 100 mg for the first two doses only, followed by 1 mg/kg dosing for the remaining doses) in patients with acute ST-segment elevation myocardial infarction. Reduce the dosage in patients ≥75 years of age [see Dosage and Administration (2.4) ]. Unless contraindicated, administer aspirin to all patients as soon as they are identified as having STEMI and continue dosing with 75 to 325 mg once daily. When administered in conjunction with a thrombolytic (fibrin specific or non–fibrin specific), administer Lovenox between 15 minutes before and 30 minutes after the start of fibrinolytic therapy. The usual duration of Lovenox therapy is 8 days or until hospital discharge. For patients managed with percutaneous coronary intervention (PCI), if the last Lovenox subcutaneous administration was given less than 8 hours before balloon inflation, no additional dosing is needed. If the last Lovenox subcutaneous administration was given more than 8 hours before balloon inflation, administer an intravenous bolus of 0.3 mg/kg of Lovenox [see Warnings and Precautions (5.2) ]. 2.3 Dose Reduction for Patients with Severe Renal Impairment The recommended prophylaxis and treatment dosage regimens for patients with severe renal impairment (creatinine clearance <30 mL/min) are described in Table 1 [see Use in Specific Populations (8.7) and Clinical Pharmacology (12.3) ] . Table 1: Dosage Regimens for Patients with Severe Renal Impairment (creatinine clearance <30 mL/minute) Indication Dosage Regimen Prophylaxis in abdominal surgery 30 mg administered subcutaneously once daily Prophylaxis in hip or knee replacement surgery 30 mg administered subcutaneously once daily Prophylaxis in medical patients during acute illness 30 mg administered subcutaneously once daily Inpatient treatment of acute deep vein thrombosis with or without pulmonary embolism, when administered in conjunction with warfarin sodium 1 mg/kg administered subcutaneously once daily Outpatient treatment of acute deep vein thrombosis without pulmonary embolism, when administered in conjunction with warfarin sodium 1 mg/kg administered subcutaneously once daily Prophylaxis of ischemic complications of unstable angina and non–Q-wave myocardial infarction, when concurrently administered with aspirin 1 mg/kg administered subcutaneously once daily Treatment of acute ST-segment elevation myocardial infarction in patients <75 years of age, when administered in conjunction with aspirin 30 mg single intravenous bolus plus a 1 mg/kg subcutaneous dose followed by 1 mg/kg administered subcutaneously once daily Treatment of acute ST-segment elevation myocardial infarction in geriatric patients ≥75 years of age, when administered in conjunction with aspirin 1 mg/kg administered subcutaneously once daily (no initial bolus) Although no dose adjustment is recommended in patients with creatinine clearance 30 to 50 mL/min and creatinine clearance 50 to 80 mL/min, observe these patients frequently for signs and symptoms of bleeding. 2.4 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) [see Use in Specific Populations (8.5) and Clinical Pharmacology (12.3) ] . No dose adjustment is necessary for other indications in geriatric patients unless kidney function is impaired [see Dosage and Administration (2.2) ] . 2.5 Administration Do not administer Lovenox by intramuscular injection. Administer Lovenox by intravenous or subcutaneous injection only. Lovenox 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. Use a tuberculin syringe or equivalent when using Lovenox multiple-dose vials to assure withdrawal of the appropriate volume of drug. 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. Provide proper training in subcutaneous injection technique before allowing self-injection (with or without the assistance of an injection device). Subcutaneous Injection Technique Position patients in a supine position for Lovenox administration by deep subcutaneous injection. Do not expel the air bubble from the prefilled syringes before the injection, to avoid the loss of drug. Do not inject into skin that has bruises or scars. Do not inject through clothes. Alternate injection sites between the left and right anterolateral and left and right posterolateral abdominal wall. Introduce the whole length of the needle into a skin fold held between the thumb and forefinger; hold the skin fold throughout the injection. To minimize bruising, do not rub the injection site after completion of the injection. Lovenox prefilled syringes and graduated prefilled syringes are for single, one-time use only and are available with a system that shields the needle after injection. Remove the prefilled syringe from the packaging by peeling at the arrow as directed on the lid. Do not remove by pulling on the plunger as this may damage the syringe. Remove the needle shield by pulling it straight off the syringe (see Figure A ). If less than the full syringe volume is needed to administer the prescribed dose, eject syringe contents until the prescribed dose is left in the syringe. Figure A Inject using standard technique, pushing the plunger to the bottom of the syringe (see Figure B ). Figure B Remove the syringe from the injection site keeping your finger on the plunger rod (see Figure C ). Figure C Orient the needle away from you and others, and activate the safety system by firmly pushing the plunger rod. The protective sleeve will automatically cover the needle and an audible "click" will be heard to confirm shield activation (see Figure D ). Figure D Immediately dispose of the syringe in the nearest sharps container (see Figure E ). Figure E NOTE: The safety system can only be activated once the syringe has been emptied. Activation of the safety system must be done only after removing the needle from the patient's skin. Do not replace the needle shield after injection. The safety system should not be sterilized. Activation of the safety system may cause minimal splatter of fluid. For optimal safety, activate the system while orienting it downwards away from yourself and others. Figure A Figure B Figure C Figure D Figure E Intravenous (Bolus) Injection Technique Use the multiple-dose vial for intravenous injections. Administer Lovenox through an intravenous line. Do not mix or coadminister Lovenox with other medications. Flush the intravenous access device with a sufficient volume of saline or dextrose solution prior to and following the intravenous bolus administration of Lovenox, to prevent mixing of drugs. Lovenox is compatible with normal saline solution (0.9%) or 5% dextrose in water. 2.6 Monitoring for Safety During therapy monitor complete blood counts including platelets and stool occult blood. Assess for signs and symptoms of bleeding. In patients with renal impairment anti-Factor Xa levels may be used to monitor the anticoagulant effects of Lovenox. If during Lovenox therapy abnormal coagulation parameters or bleeding should occur, anti-Factor Xa levels may be used to monitor the anticoagulant effects of Lovenox [see Clinical Pharmacology (12.3) ] . Prothrombin Time (PT) and Activated Partial Thromboplastin Time (aPTT) are not adequate for monitoring the anticoagulant effects of Lovenox.

6 ADVERSE REACTIONS The following serious adverse reactions are also discussed in other sections of the labeling: Spinal/epidural hematomas [see Boxed Warning and Warnings and Precautions (5.1) ] Increased Risk of Hemorrhage [see Warnings and Precautions (5.1) ] Thrombocytopenia [see Warnings and Precautions (5.5) ] Most common adverse reactions (>1%) were bleeding, anemia, thrombocytopenia, elevation of serum aminotransferase, diarrhea, nausea, ecchymosis, fever, edema, peripheral edema, dyspnea, confusion, and injection site pain. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact sanofi-aventis at 1-800-633-1610 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice. During clinical development for the approved indications, 15,918 patients were exposed to Lovenox. These included 1,228 for prophylaxis of deep vein thrombosis following abdominal surgery in patients at risk for thromboembolic complications, 1,368 for prophylaxis of deep vein thrombosis following hip or knee replacement surgery, 711 for prophylaxis of deep vein thrombosis in medical patients with severely restricted mobility during acute illness, 1,578 for prophylaxis of ischemic complications in unstable angina and non–Q-wave myocardial infarction, 10,176 for treatment of acute ST-elevation myocardial infarction, and 857 for treatment of deep vein thrombosis with or without pulmonary embolism. Lovenox doses in the clinical trials for prophylaxis of deep vein thrombosis following abdominal or hip or knee replacement surgery or in medical patients with severely restricted mobility during acute illness ranged from 40 mg subcutaneously once daily to 30 mg subcutaneously twice daily. In the clinical studies for prophylaxis of ischemic complications of unstable angina and non–Q-wave myocardial infarction doses were 1 mg/kg every 12 hours and in the clinical studies for treatment of acute ST-segment elevation myocardial infarction Lovenox doses were a 30 mg intravenous bolus followed by 1 mg/kg every 12 hours subcutaneously. Hemorrhage The following rates of major bleeding events have been reported during clinical trials with Lovenox (see Tables 2 to 7). Table 2: Major Bleeding Episodes following Abdominal and Colorectal Surgery Bleeding complications were considered major: (1) if the hemorrhage caused a significant clinical event, or (2) if accompanied by a hemoglobin decrease ≥2 g/dL or transfusion of 2 or more units of blood products. Retroperitoneal, intraocular, and intracranial hemorrhages were always considered major.

Since aminotransferase determinations are important in the differential diagnosis of myocardial infarction, liver disease, and pulmonary emboli, elevations that might be caused by drugs like Lovenox should be interpreted with caution. Local Reactions Local irritation, pain, hematoma, ecchymosis, and erythema may follow subcutaneous injection of Lovenox. Adverse Reactions in Patients Receiving Lovenox for Prophylaxis or Treatment of DVT, PE Other adverse reactions that were thought to be possibly or probably related to treatment with Lovenox, heparin, or placebo in clinical trials with patients undergoing hip or knee replacement surgery, abdominal or colorectal surgery, or treatment for DVT and that occurred at a rate of at least 2% in the Lovenox group, are provided below (see Tables 8 to 11).

Serious adverse events with Lovenox or heparin in a clinical trial in patients with unstable angina or non–Q-wave myocardial infarction that occurred at a rate of at least 0.5% in the Lovenox group are provided below (see Table 12 ). Table 12: Serious Adverse Events Occurring at ≥0.5% Incidence in Lovenox-Treated Patients with Unstable Angina or Non–Q-Wave Myocardial Infarction Dosing Regimen Lovenox 1 mg/kg q12h subcutaneously Heparin aPTT Adjusted Intravenous Therapy Adverse Event n=1578 n (%) n=1529 n (%) Atrial fibrillation 11 (0.70) 3 (0.20) Heart failure 15 (0.95) 11 (0.72) Lung edema 11 (0.70) 11 (0.72) Pneumonia 13 (0.82) 9 (0.59) Adverse Reactions in Lovenox-Treated Patients with Acute ST-Segment Elevation Myocardial Infarction In a clinical trial in patients with acute ST-segment elevation myocardial infarction, thrombocytopenia occurred at a rate of 1.5%. 6.2 Postmarketing Experience The following adverse reactions have been identified during postapproval use of Lovenox. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. There have been reports of epidural or spinal hematoma formation with concurrent use of Lovenox and spinal/epidural anesthesia or spinal puncture. The majority of patients had a postoperative indwelling epidural catheter placed for analgesia or received additional drugs affecting hemostasis such as NSAIDs. Many of the epidural or spinal hematomas caused neurologic injury, including long-term or permanent paralysis. Local reactions at the injection site (e.g. nodules, inflammation, oozing), systemic allergic reactions (e.g. pruritus, urticaria , anaphylactic/anaphylactoid reactions including shock), vesiculobullous rash, cases of hypersensitivity cutaneous vasculitis, purpura, skin necrosis (occurring at either the injection site or distant from the injection site), thrombocytosis, and thrombocytopenia with thrombosis [see Warnings and Precautions (5.5) ] have been reported. Cases of hyperkalemia have been reported. Most of these reports occurred in patients who also had conditions that tend toward the development of hyperkalemia (e.g., renal dysfunction, concomitant potassium-sparing drugs, administration of potassium, hematoma in body tissues). Very rare cases of hyperlipidemia have also been reported, with one case of hyperlipidemia, with marked hypertriglyceridemia, reported in a diabetic pregnant woman; causality has not been determined. Cases of headache, hemorrhagic anemia, eosinophilia, alopecia, hepatocellular and cholestatic liver injury have been reported. Osteoporosis has also been reported following long-term therapy.
