Enoxaparin Sodium: Brands, Price & Uses in Bangladesh

Established / FDA-Approved Uses

• Prophylaxis of deep vein thrombosis (DVT): in patients undergoing abdominal surgery, hip replacement surgery, or knee replacement surgery, and in medical patients with severely restricted mobility during acute illness.
• Treatment of acute DVT, with or without pulmonary embolism (PE), when administered in conjunction with warfarin sodium (inpatient) or without warfarin (outpatient, for DVT without PE).
• Unstable angina and non-Q-wave myocardial infarction: for the prevention of ischemic complications, administered concurrently with aspirin.
• Acute ST-segment elevation myocardial infarction (STEMI): in patients managed medically or with subsequent percutaneous coronary intervention (PCI), administered with aspirin.
• Prevention of clot formation in the extracorporeal circuit during hemodialysis.

Guideline-Supported / Adjunct Uses

• Bridging anticoagulation in patients temporarily interrupting oral anticoagulants (e.g. around surgery), per clinical guideline recommendations, though this is not a formal labeled indication.
• Thromboprophylaxis in hospitalized medical patients (e.g. heart failure, severe respiratory disease) with restricted mobility, as an FDA-approved use noted above but frequently guided by institutional protocols.

Enoxaparin Sodium must always be prescribed and monitored by a qualified physician; the specific dose and duration depend on the indication being treated.

General Principles

Enoxaparin Sodium dosing is expressed in milligrams (mg) or anti-Xa International Units (IU) depending on the product and region, and must be individualized to the indication. Doses below are typical adult regimens; always follow the prescribing physician's instructions.

Renal Impairment

In patients with severe renal impairment (creatinine clearance <30 mL/min), the dose of Enoxaparin Sodium must be reduced (e.g. to once-daily dosing) because of reduced clearance and increased bleeding risk; consult a physician for individualized adjustment.

Injection Technique

• Enoxaparin Sodium is administered by deep subcutaneous injection, alternating between the left and right anterolateral or posterolateral abdominal wall.
• Do not expel the air bubble from a pre-filled syringe before injection, as it helps ensure the full dose is delivered.
• Rotate injection sites and do not rub the site after injection, to minimize bruising.
• Enoxaparin Sodium should not be administered by intramuscular injection.

Do not use Enoxaparin Sodium interchangeably (unit-for-unit) with unfractionated heparin or with other low molecular weight heparin products, as they differ in manufacturing, dosing, and clinical activity.

The most common adverse effects of Enoxaparin Sodium relate to its anticoagulant action and the injection procedure itself:

• Very common: bleeding/hemorrhage (of varying severity, from minor bruising to major bleeding), local injection-site reactions (pain, bruising, erythema, hematoma, irritation).
• Common: elevated liver transaminases (AST/ALT), thrombocytopenia (mild, non-immune), anemia.
• Less common but serious: heparin-induced thrombocytopenia (HIT), allergic/hypersensitivity reactions (including skin rash, urticaria, rarely anaphylaxis), spinal or epidural hematoma in patients receiving neuraxial anesthesia (see Precautions), osteoporosis with prolonged use.
• Rare: skin necrosis at the injection site, systemic hypersensitivity reactions.

Patients should seek urgent medical attention for signs of unusual bleeding (blood in urine or stool, unusual bruising, prolonged bleeding from cuts), sudden back pain, numbness, or weakness in the legs (which may indicate spinal/epidural hematoma), or signs of an allergic reaction.
