IV Administration
IV injection may be given undiluted or diluted in 50-100 mL NS or D5W
Infusion: Dilute in NS, D5W, or other compatible fluid
Continuous IV therapy is preferred because intermittent IV therapy produces a higher incidence of bleeding abnormalities
Contra Indications
Patients predisposed to active bleeding including thrombocytopenia, peptic ulcer disease, cerebrovascular disorders, haemorrhagic blood disorders, bacterial endocarditis, severe hypertension, oesophageal varices. Recent surgery at sites where haemorrhage would be an especial risk. Severe renal and hepatic impairment. Cerebral or subarachnoid haemorrhage, abdominal or thoracic bleeding into closed space, severe traumatic bleed, hepatic, renal, splenic or arterial injury, severe haemostatic defect, arterial thrombosis with heparin-associated thrombocytopenia. IM admin.
Precautions

Interactions
Enhanced anticoagulant effect w/ other drugs affecting platelet function or the coagulation system (e.g. platelet aggregation inhibitors, thrombolytic agents, salicylates, NSAIDs, vit K antagonists, dextrans, activated protein C). Decreased anticoagulant effect w/ gyceryl trinitrate infusion. Increased risk of hyperkalaemia w/ ACE inhibitors or angiotensin II antagonists.

>10%
Heparin-induced thrombocytopenia, possibly delayed (10-30% )
Frequency Not Defined
Mild pain,Hematoma,Hemorrhage,Local irritation,Erythema,Injection site ulcer (after deep SC injection),Increased liver aminotransferase,Anaphylaxis,Immune hypersensitivity reaction,Osteoporosis (long-term, high-dose use)
Potentially Fatal: Heparin-induced thrombocytopenia with or without thrombosis; bleeding.
Mechanism of Action
Heparin increases the inhibitory action of antithrombin III (AT III) on clotting factors XIIa, XIa, IXa, Xa and thrombin. This inhibits the conversion of prothrombin to thrombin and fibrinogen to fibrin. It also inhibits platelet function. It may reduce the activity of ATIII at very high doses.
