Heparine Choay (Heparin Sodium)

Heparine Choay is used in clinical practice to reduce the risk of clot formation in several high‑risk situations. It is indicated for patients who need anticoagulation to prevent or treat venous thromboembolic events.

• Prevention of venous thromboembolism after orthopedic or general surgery
• Treatment of acute deep vein thrombosis (DVT)
• Prevention of pulmonary embolism in at‑risk patients
• Anticoagulation during cardiac or vascular surgery
• Prophylaxis in patients with prolonged immobilisation

Heparine Choay may cause a range of adverse reactions, most of which are related to its anticoagulant activity. Patients should be monitored for both common and serious events.

Common

• Minor bruising or bleeding at the injection site
• Small hematomas
• Mild epistaxis (nosebleed)
• Gastrointestinal upset or nausea
• Transient elevation of liver enzymes

Serious

• Major bleeding (intracranial, gastrointestinal, or surgical site)
• Heparin‑induced thrombocytopenia (HIT)
• Allergic reactions such as urticaria or angioedema
• Spontaneous spinal or epidural hematoma

Before initiating Heparine Choay, clinicians should evaluate patient‑specific factors that could increase bleeding risk or affect drug safety. Appropriate monitoring and dose adjustments are essential.

• Assess baseline coagulation parameters (aPTT, platelet count)
• Review history of bleeding disorders or recent major surgery
• Use caution in patients with renal or hepatic impairment
• Avoid use in individuals with known hypersensitivity to heparin or pork products
• Monitor for signs of heparin‑induced thrombocytopenia during therapy
• Consider pregnancy status; data are limited
• Adjust dose in elderly patients as needed

Heparine Choay can interact with several medications that affect hemostasis or platelet function. Some combinations should be avoided, while others require careful monitoring.

Avoid

• Concurrent use of other anticoagulants (e.g., warfarin, direct oral anticoagulants)
• Antiplatelet agents such as clopidogrel or aspirin at high doses
• Thrombolytic therapy (e.g., alteplase)

Use with caution

• Non‑steroidal anti‑inflammatory drugs (NSAIDs) and selective COX‑2 inhibitors
• Certain antibiotics (e.g., quinolones) that may potentiate bleeding
• Herbal supplements with antiplatelet properties (e.g., ginkgo, garlic)
• High‑dose vitamin K antagonists
• Any medication that may alter platelet function or coagulation pathways
