Indications & Usage
1 INDICATIONS AND USAGE Heparin Sodium Injection is indicated for: Prophylaxis and treatment of venous thrombosis and pulmonary embolism Prevention of postoperative deep venous thrombosis and pulmonary embolism in patients undergoing major abdominothoracic surgery or who, for other reasons, are at risk of developing thromboembolic disease Atrial fibrillation with embolization Treatment of acute and chronic consumptive coagulopathies (disseminated intravascular coagulation) Prevention of clotting in arterial and cardiac surgery Prophylaxis and treatment of peripheral arterial embolism Anticoagulant use in blood transfusions, extracorporeal circulation, and dialysis procedures Heparin Sodium I…
Mechanism of Action
12.1 Mechanism of Action Heparin interacts with the naturally occurring plasma protein, Antithrombin III, to induce a conformational change, which markedly enhances the serine protease activity of Antithrombin III, thereby inhibiting the activated coagulation factors involved in the clotting sequence, particularly Xa and IIa. Small amounts of heparin inhibit Factor Xa, and larger amounts inhibit thrombin (Factor IIa). Heparin also prevents the formation of a stable fibrin clot by inhibiting the activation of the fibrin stabilizing factor. Heparin does not have fibrinolytic activity; therefore, it will not lyse existing clots.

Drug Interactions
7 DRUG INTERACTIONS Drugs that interfere with platelet aggregation: May induce bleeding ( 7.2 ) 7.1 Oral Anticoagulants Heparin sodium may prolong the one-stage prothrombin time. Therefore, when heparin sodium is given with dicumarol or warfarin sodium, a period of at least 5 hours after the last intravenous dose or 24 hours after the last subcutaneous dose should elapse before blood is drawn, if a valid prothrombin time is to be obtained. 7.2 Platelet Inhibitors Drugs such as NSAIDS (including…

Patient Counseling Information
17 PATIENT COUNSELING INFORMATION Hemorrhage Inform patients that it may take them longer than usual to stop bleeding, that they may bruise and/or bleed more easily when they are treated with heparin, and that they should report any unusual bleeding or bruising to their physician. Hemorrhage can occur at virtually any site in patients receiving heparin. Fatal hemorrhages have occurred [see Warnings and Precautions ( 5.2 )] . Prior to Surgery Advise patients to inform physicians and dentists that they are receiving heparin before any surgery is scheduled [see Warnings and Precautions ( 5.2 )] .…
