2000 IU/0.2 mL and 6000 IU/0.6 mL soln for inj: All patients should be evaluated for a bleeding disorder before administration of Enoxaparin, unless the medication is needed urgently, or as prescribed by the physician.
Abdominal surgery: In patients undergoing abdominal surgery who are at risk for thromboembolic complications, the recommended dose of Enoxaparin 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 of administration has been well tolerated in clinical trials.
Hip or Knee Replacement surgery: In patients undergoing hip or knee replacement surgery, the recommended surgery dose of Enoxaparin 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 is given initially 12 hours prior to surgery may be considered. In the initial phase of thromboprophylaxis in hip replacement surgery patients, continued prophylaxis with Enoxaparin 40 mg once a day administered by SC injection for 3 weeks is recommended.
The usual duration of administration is 7 to 10 days; up to 14 days of administration has been well tolerated 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 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 has been well tolerated in the controlled clinical trial.
Administration: Enoxaparin 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.
Enoxaparin is administered by SC injection. It must not be administered by intramuscular injection.
Enoxaparin is intended for use under the guidance of a physician. Patients may self-inject only if their physician determines that it is appropriate and with medical follow-up, as necessary. Proper training in subcutaneous injection technique (with or without the assistance of an injection device) should be provided.
Subcutaneous Injection Technique: Patients should be lying down and Enoxaparin administered by deep SC injection. To avoid the loss of the drug, do not expel the air bubble from the syringe before the injection. Administration should be alternated between the left and right anterolateral and left and right posterolateral abdominal wall. The whole length of the needle should be introduced into a skin fold held between the thumb and forefinger; the skin fold should be held throughout the injection. To minimize bruising, do not rub the injection site after completion of the injection.
4000 IU/0.4 mL soln for inj: Posology: Prophylaxis of venous thromboembolic disease in moderate and high-risk surgical patients: Individual thromboembolic risk for patients can be estimated using a validated risk stratification model. In patients at moderate risk of thromboembolism, the recommended dose of enoxaparin sodium is 2,000 IU (20 mg) once daily by subcutaneous (SC) injection. Pre-operative initiation (2 hours before surgery) of enoxaparin sodium 2,000 IU (20 mg) was proven effective and safe in moderate-risk surgery.
In moderate-risk patients, enoxaparin sodium treatment should be maintained for a minimum period of 7-10 days whatever the recovery status (e.g., mobility).
Prophylaxis should be continued until the patient no longer has significantly reduced mobility.
In patients at high risk of thromboembolism, the recommended dose of enoxaparin sodium is 4,000 IU (40 mg) once daily given by SC injection preferably started 12 hours before surgery. If there is a need for earlier than 12 hours of enoxaparin sodium pre-operative prophylactic initiation (e.g., high-risk patient waiting for a deferred orthopedic surgery), the last injection should be administered no later than 12 hours prior to surgery and resumed 12 hours after surgery.
For patients who undergo major orthopedic surgery an extended thromboprophylaxis for up to 5 weeks is recommended.
For patients with high venous thromboembolism (VTE) risk who undergo abdominal or pelvic surgery for cancer, an extended thromboprophylaxis for up to 4 weeks is recommended.
Prophylaxis of venous thromboembolism in medical patients: The recommended dose of enoxaparin sodium is 4,000 IU (40 mg) once daily by SC injection. Treatment with enoxaparin sodium is prescribed for at least 6 to 14 days whatever the recovery status (e.g., mobility). The benefit is not established for treatment longer than 14 days.
Treatment of DVT and PE: Enoxaparin sodium can be administered SC either as a once-daily injection of 150 IU/kg (1.5 mg/kg) or as twice-daily injections of 100 IU/kg (1 mg/kg).
The regimen should be selected by the physician based on an individual assessment including an evaluation of the thromboembolic risk and of the risk of bleeding. The dose regimen of 150 IU/kg (1.5 mg/kg) administered once daily should be used in uncomplicated patients with a low risk of VTE recurrence. The dose regimen of 100 IU/kg (1 mg/kg) administered twice daily should be used in all other patients such as those with obesity, symptomatic PE, cancer, recurrent VTE or proximal (vena iliaca) thrombosis.
Enoxaparin sodium treatment is prescribed for an average period of 10 days. Oral anticoagulant therapy should be initiated when appropriate.
Prevention of thrombus formation during hemodialysis: The recommended dose is 100 IU/kg (1 mg/kg) of enoxaparin sodium.
For patients with a high risk of hemorrhage, the dose should be reduced to 50 IU/kg (0.5 mg/kg) for double vascular access or 75 IU/kg (0.75 mg/kg) for single vascular access.
During hemodialysis, enoxaparin sodium should be introduced into the arterial line of the circuit at the beginning of the dialysis session. The effect of this dose is usually sufficient for a 4-hour session; however, if fibrin rings are found, for example after a longer than normal session, a further dose of 50 IU to 100 IU/kg (0.5 to 1 mg/kg) may be given.
No data are available on patients using enoxaparin sodium for prophylaxis or treatment and during hemodialysis sessions.
Acute coronary syndrome: treatment of unstable angina and NSTEMI and treatment of acute STEMI.
For treatment of unstable angina and NSTEMI, the recommended dose of enoxaparin sodium is 100 IU/kg (1 mg/kg) every 12 hours by SC injection administered in combination with antiplatelet therapy. Treatment should be maintained for a minimum of 2 days and continued until clinical stabilization. The usual duration of treatment is 2 to 8 days.
Acetylsalicylic acid is recommended for all patients without contraindications at an initial oral loading dose of 150-300 mg (in acetylsalicylic acid-naive patients) and a maintenance dose of 75-325 mg/day long-term regardless of the treatment strategy.
For treatment of acute STEMI, the recommended dose of enoxaparin sodium is a single intravenous (IV) bolus of 3,000 IU (30 mg) plus a 100 IU/kg (1 mg/kg) SC dose followed by 100 IU/kg (1 mg/kg) administered SC every 12 hours (maximum 10,000 IU (100 mg) for each of the first two SC doses). Appropriate antiplatelet therapy such as oral acetylsalicylic acid (75 mg to 325 mg once daily) should be administered concomitantly unless contraindicated. The recommended duration of treatment is 8 days or until hospital discharge, whichever comes first. When administered in conjunction with a thrombolytic (fibrin specific or non-fibrin specific), enoxaparin sodium should be given between 15 minutes before and 30 minutes after the start of fibrinolytic therapy.
For dosage in patients ≥75 years of age.
For patients managed with PCI, if the last dose of enoxaparin sodium SC was given less than 8 hours before balloon inflation, no additional dosing is needed. If the last SC administration was given more than 8 hours before balloon inflation, an IV bolus of 30 IU/kg (0.3 mg/kg) enoxaparin sodium should be administered.
Pediatric population: The safety and efficacy of enoxaparin sodium in the pediatric population have not been established.
Elderly: For all indications except STEMI, no dose reduction is necessary for elderly patients, unless kidney function is impaired.
For treatment of acute STEMI in elderly patients ≥75 years of age, an initial IV bolus must not be used. Initiate dosing with 75 IU/kg (0.75 mg/kg) SC every 12 hours (maximum 7,500 IU (75 mg) for each of the first two SC doses only, followed by 75 IU/kg (0.75 mg/kg) SC dosing for the remaining doses).
Hepatic impairment: Limited data are available in patients with hepatic impairment and caution should be used in these patients.
Renal impairment: Severe renal impairment: Enoxaparin sodium is not recommended for patients with end-stage renal disease (creatinine clearance <15 mL/min) due to the lack of data in this population outside the prevention of thrombus formation in extracorporeal circulation during hemodialysis.
Dosage table for patients with severe renal impairment (creatinine clearance [15-30] mL/min): The recommended dosage adjustments do not apply to the hemodialysis indication. (See Table 1.)

Moderate and mild 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, careful clinical monitoring is advised.
Method of administration: Enoxaparin sodium injection should not be administered by the intramuscular route.
For the prophylaxis of venous thromboembolic disease following surgery, treatment of DVT and PE, treatment of unstable angina and NSTEMI, enoxaparin sodium should be administered by SC injection.
For acute STEMI, treatment is to be initiated with a single IV bolus injection immediately followed by an SC injection.
For the prevention of thrombus formation in the extracorporeal circulation during hemodialysis, it is administered through the arterial line of a dialysis circuit.
The pre-filled disposable syringe is ready for immediate use.
SC injection technique: Injection should be made preferably when the patient is lying down. Enoxaparin sodium is administered by deep SC injection.
Do not expel the air bubble from the syringe before the injection to avoid the loss of drug when using pre-filled syringes. When the quantity of drug to be injected requires to be adjusted based on the patient's body weight, use the graduated pre-filled syringes to reach the required volume by discarding the excess before injection. Be aware that in some cases it is not possible to achieve an exact dose due to the graduations on the syringe, and in such case, the volume shall be rounded up to the nearest graduation.
The administration should be alternated between the left and right anterolateral or posterolateral abdominal wall.
The whole length of the needle should be introduced vertically into a skin fold and gently held between the thumb and index finger. The skin fold should not be released until the injection is complete. Do not rub the injection site after administration.
Note for the pre-filled syringes fitted with an automatic safety system: The safety system is triggered at the end of the injection.
In case of self-administration, the patient should be advised to follow instructions provided in the patient information leaflet included in the pack of this medicine.
IV (bolus) injection (for acute STEMI indication only): For acute STEMI, treatment is to be initiated with a single IV bolus injection immediately followed by an SC injection.
For IV injection, either the multidose vial or pre-filled syringe can be used.
Enoxaparin sodium should be administered through an IV line. It should not be mixed or co-administered with other medications. To avoid the possible mixture of enoxaparin sodium with other drugs, the IV access chosen should be flushed with a sufficient amount of saline or dextrose solution prior to and following the IV bolus administration of enoxaparin sodium to clear the port of drug. Enoxaparin sodium may be safely administered with normal saline solution (0.9%) or 5% dextrose in water.
Initial 3,000 IU (30 mg) bolus: For the initial 3,000 IU (30 mg) bolus, using an enoxaparin sodium graduated pre-filled syringe, expel the excessive volume to retain only 3,000 IU (30 mg) in the syringe. The 3,000 IU (30 mg) dose can then be directly injected into the IV line.
Additional bolus for PCI when last SC administration was given more than 8 hours before balloon inflation: For patients being managed with PCI, an additional IV bolus of 30 IU/kg (0.3 mg/kg) is to be administered if the last SC administration was given more than 8 hours before balloon inflation.
In order to assure the accuracy of the small volume to be injected, it is recommended to dilute the drug to 300 IU/mL (3 mg/mL).
To obtain a 300 IU/mL (3 mg/mL) solution, it is recommended to use a 6,000 IU (60 mg) enoxaparin sodium pre-filled syringe, and a 50 mL infusion bag (i.e., using either normal saline solution (0.9%) or 5% dextrose in water) as follows: Withdraw 30 mL from the infusion bag with a syringe and discard the liquid. Inject the complete contents of the 6,000 IU (60 mg) enoxaparin sodium pre-filled syringe into the 20 mL remaining in the bag. Gently mix the contents of the bag. Withdraw the required volume of diluted solution with a syringe for administration into the IV line.
After dilution is completed, the volume to be injected can be calculated using the following formula [Volume of diluted solution (mL) = Patient weight (kg) x 0.1] or using the table as follows. It is recommended to prepare the dilution immediately before use.
Volume to be injected through IV line after dilution is completed at a concentration of 300 IU (3 mg)/mL.
Arterial line injection: It is administered through the arterial line of a dialysis circuit for the prevention of thrombus formation in the extracorporeal circulation during hemodialysis. Switch between enoxaparin sodium and oral anticoagulants.
Switch between enoxaparin sodium and vitamin K antagonists (VKA): Clinical monitoring and laboratory tests [prothrombin time expressed as the International Normalized Ratio (INR)] must be intensified to monitor the effect of VKA.
As there is an interval before the VKA reaches its maximum effect, enoxaparin sodium therapy should be continued at a constant dose for as long as necessary in order to maintain the INR within the desired therapeutic range for the indication in two successive tests.
For patients currently receiving a VKA, the VKA should be discontinued and the first dose of enoxaparin sodium should be given when the INR has dropped below the therapeutic range. (See Table 2.)

Switch between enoxaparin sodium and direct oral anticoagulants (DOAC): For patients currently receiving enoxaparin sodium, discontinue enoxaparin sodium and start the DOAC 0 to 2 hours before the time that the next scheduled administration of enoxaparin sodium would be due as per DOAC label.
For patients currently receiving a DOAC, the first dose of enoxaparin sodium should be given at the time the next DOAC dose would be taken.
Administration in spinal/epidural anesthesia or lumbar puncture: Should the physician decide to administer anticoagulation in the context of epidural or spinal anesthesia/analgesia or lumbar puncture, careful neurological monitoring is recommended due to the risk of neuraxial hematomas.
At doses used for prophylaxis: A puncture-free interval of at least 12 hours shall be kept between the last injection of enoxaparin sodium at prophylactic doses and the needle or catheter placement.
For continuous techniques, a similar delay of at least 12 hours should be observed before removing the catheter.
For patients with creatinine clearance [15-30] mL/min, consider doubling the timing of puncture/catheter placement or removal to at least 24 hours.
The 2 hours preoperative initiation of enoxaparin sodium 2,000 IU (20 mg) is not compatible with neuraxial anesthesia.
At doses used for treatment: A puncture-free interval of at least 24 hours shall be kept between the last injection of enoxaparin sodium at curative doses and the needle or catheter placement.
For continuous techniques, a similar delay of 24 hours should be observed before removing the catheter.
For patients with creatinine clearance [15-30] mL/min, consider doubling the timing of puncture/catheter placement or removal to at least 48 hours.
Patients receiving the twice daily doses (i.e., 75 IU/kg (0.75 mg/kg) twice daily or 100 IU/kg (1 mg/kg) twice daily) should omit the second enoxaparin sodium dose to allow a sufficient delay before catheter placement or removal.
Anti-Xa levels are still detectable at these time points, and these delays are not a guarantee that neuraxial hematoma will be avoided.
Likewise, consider not using enoxaparin sodium until at least 4 hours after the spinal/epidural puncture or after the catheter has been removed. The delay must be based on a benefit-risk assessment considering both the risk for thrombosis and the risk for bleeding in the context of the procedure and patient risk factors.
