Heparine Leo (Heparin Sodium)

Heparine Leo is indicated for several antithrombotic purposes where rapid anticoagulation is required.

• Prevention and treatment of venous thromboembolism (deep‑vein thrombosis and pulmonary embolism).
• Prophylaxis of clot formation during cardiac surgery, coronary artery bypass grafting, and hemodialysis.
• Management of acute coronary syndromes, including unstable angina and non‑ST‑segment elevation myocardial infarction.
• Thromboprophylaxis in patients undergoing major orthopedic procedures such as hip or knee replacement.
• Anticoagulation for patients receiving extracorporeal membrane oxygenation (ECMO) or other extracorporeal circuits.

Heparine Leo may cause a range of adverse reactions, most of which are related to its anticoagulant activity.

Common

• Minor bleeding at injection sites or from mucous membranes.
• Small bruising or hematoma formation.
• Transient elevation of liver enzymes.
• Nausea or mild gastrointestinal discomfort.
• Local irritation or phlebitis at the infusion site.

Serious

• Major hemorrhage, including intracranial or gastrointestinal bleeding.
• Heparin‑induced thrombocytopenia (HIT) with paradoxical clot formation.
• Allergic reactions such as urticaria, angioedema, or anaphylaxis.
• Spontaneous spinal or epidural hematoma when used near the spine.
• Severe liver injury or hepatic necrosis (rare).

When prescribing or administering Heparine Leo, clinicians should consider several safety factors.

• Assess baseline coagulation parameters (aPTT, platelet count) before initiation and monitor regularly.
• Use caution in patients with a history of bleeding disorders, recent surgery, or trauma.
• Evaluate renal and hepatic function, as impairment may affect drug clearance.
• Avoid use in patients with known hypersensitivity to heparin or pork‑derived products.
• Consider alternative anticoagulation in pregnant women, as safety data are limited.
• Educate patients about signs of bleeding and when to seek medical attention.

Heparine Leo can interact with other agents that affect hemostasis or platelet function.

Avoid

• Concurrent use of other anticoagulants (e.g., warfarin, direct oral anticoagulants) without careful monitoring.
• High‑dose antiplatelet drugs such as clopidogrel or aspirin when bleeding risk is elevated.
• Thrombolytic agents (e.g., alteplase, streptokinase) due to additive hemorrhagic risk.

Use with caution

• Non‑steroidal anti‑inflammatory drugs (NSAIDs) that may increase gastrointestinal bleeding.
• Certain antibiotics (e.g., vancomycin) that can potentiate platelet dysfunction.
• Herbal supplements such as ginkgo biloba, garlic, or ginseng that have antiplatelet properties.
• Vitamin K antagonists, requiring close monitoring of INR and aPTT.
