Prophylaxis of clotting in extracorporeal circulation in haemodialysis or haemofiltration, Prophylaxis of clotting in extracorporeal circulation in haemodialysis or haemofiltration, Unstable angina, Prophylaxis of venous thromboembolism during surgical procedures, Venous thromboembolism.
Dalteparin Na is an antithrombotic agent, which acts mainly through its ability to potentiate the inhibition of factor Xa and thrombin by antithrombin. It has a relatively higher ability to potentiate factor Xa inhibition than to prolong aPTT.
Intravenous- Prophylaxis of clotting in extracorporeal circulation in haemodialysis or haemofiltration: 30-40 U/kg IV inj, then 10-15 U/kg/hr as IV infusion. Subcutaneous- Venous thromboembolism: 200 U/kg/day as a single or in 2 divided doses in pregnant and high-risk patients. Max: 18,000 U/day. Prophylaxis of venous thromboembolism during surgical procedures Moderate risk: 2,500 U given 1-2 hr pre-op then 2,500 U once daily for 5-7 days or until the patient is fully ambulant. High risk: 2,500 U given 1-2 hr before and 8-12 hr after the procedure then 5,000 U daily. Unstable angina: 120 U/kg 12 hrly continued for 5-8 days w/ low-dose aspirin. Max: 10,000 U 12 hrly.
Elevated serum transaminase levels (AST and ALT), allergic reactions (e.g. pruritus, rash, fever, inj site reaction, bullous eruption), pain on inj site. Epidural or spinal haematomas that may result in permanent paralysis, severe haemorrhage, thrombocytopenia.

Hypersensitivity. Active major bleeding, severe coagulation disorders; lumbar puncture; sympathetic block; brain, spinal cord, eye or ear surgery; severe hypertension
Increased risk of haemorrhage with other anticoagulant/ antiplatelet agents (e.g. aspirin/ dipyridamole, glycoprotein IIb/ IIIa receptor antagonists, vit K antagonists, NSAIDs, cytostatics, dextran, thrombolytics, sulfinpyrazone, probenecid, etacrynic acid). Reduced anticoagulant effect with antihistamines, cardiac glycosides, tetracycline and ascorbic acid.
Patient with increased risk of bleeding complications (e.g. following surgery or trauma, haemorrhagic stroke, thrombocytopenia or defective platelet function, uncontrolled HTN, hypertensive or diabetic retinopathy). Increased risk of spinal or epidural haematomas in patient undergoing neuraxial anaesth or spinal puncture esp with post-op use of indwelling epidural catheters. Hepatic and renal impairment. Pregnancy and lactation.
