4 CONTRAINDICATIONS
The use of Heparin Sodium Injection is contraindicated in patients with the following conditions:
- History of heparin-induced thrombocytopenia and heparin-induced thrombocytopenia and thrombosis [see Warnings and Precautions (5.3)]
- Known hypersensitivity to heparin or pork products (e.g., anaphylactoid reactions) [see Adverse Reactions (6.2)]
- In whom suitable blood coagulation tests, e.g., the whole blood clotting time, partial thromboplastin time, etc., cannot be performed at appropriate intervals (this contraindication refers to full-dose heparin; there is usually no need to monitor coagulation parameters in patients receiving low dose heparin)
- An uncontrolled active bleeding state [see Warnings and Precautions (5.4)], except when this is due to disseminated intravascular coagulation
