Hepaxane (Enoxaparin Sodium)

Hepaxane is indicated for several clinical situations where anticoagulation is required.

• Prevention and treatment of venous thromboembolism, including deep‑vein thrombosis and pulmonary embolism.
• Anticoagulation during haemodialysis procedures to maintain circuit patency.
• Prophylaxis of clot formation during intra‑arterial interventions such as angiography or catheter placement.
• Peri‑procedural anticoagulation for patients at risk of thrombosis undergoing surgery or invasive diagnostics.

Adverse reactions to Hepaxane can vary in frequency and severity, ranging from mild, self‑limiting symptoms to potentially life‑threatening events.

Common

• Injection site reactions such as erythema, pain, or bruising.
• Minor gastrointestinal discomfort, including nausea or dyspepsia.
• Transient increase in activated partial thromboplastin time (aPTT) without clinical bleeding.
• Elevated liver enzymes observed in laboratory monitoring.
• Mild headache or dizziness.

Serious

• Major bleeding events, including intracranial or gastrointestinal hemorrhage.
• Thrombocytopenia, particularly heparin‑induced thrombocytopenia (HIT).
• Allergic reactions ranging from urticaria to anaphylaxis.
• Spinal or epidural hematoma when used in conjunction with neuraxial anesthesia.
• Severe hypotension or shock related to massive bleeding.

Before prescribing Hepaxane, clinicians should evaluate patient‑specific factors and observe several precautionary measures.

• Assess renal function, as dose adjustment may be required in severe impairment.
• Review history of bleeding disorders, recent surgery, or active gastrointestinal lesions.
• Monitor platelet counts regularly to detect heparin‑induced thrombocytopenia.
• Use caution in pregnant or lactating women; benefits must outweigh potential risks.
• Avoid concomitant use with other anticoagulants or antiplatelet agents unless clinically justified.
• Adjust dose in obese patients based on actual body weight.
• Consider age‑related pharmacodynamic changes in elderly patients.

Hepaxane may interact with other medicines, affecting anticoagulant efficacy or bleeding risk.

Avoid

• Concurrent use with other parenteral anticoagulants such as unfractionated heparin or direct thrombin inhibitors.
• Simultaneous administration of potent antiplatelet drugs like clopidogrel or ticagrelor without dose adjustment.
• Combination with fibrinolytic agents (e.g., alteplase) due to heightened hemorrhagic potential.

Use with caution

• Non‑steroidal anti‑inflammatory drugs (NSAIDs) and aspirin, which can increase minor bleeding.
• Certain antibiotics (e.g., vancomycin, fluoroquinolones) that may potentiate anticoagulant effects.
• Selective serotonin reuptake inhibitors (SSRIs) or other serotonergic agents, which can impair platelet function.
• Vitamin K antagonists (warfarin) require careful INR monitoring when combined.
• Proton pump inhibitors may modestly affect absorption of co‑administered drugs.
