Medication
Indicated for Anti-coagulation therapy (Off label):
200
IU/kg
Solutions
subcutaneously
every 12 hours
or 100 units/kg subcutaneous
Indicated for Anticoagulant in the extracorporeal circuit during hemodialysis:
Intravenous
Dialysis sessions less than 4 hours:
Initial bolus (via the vascular side of the circuit or IV): 4,500 anti-Xa units at the start of dialysis; usually reaches plasma concentrations ranging from 0.5 to 1 anti-Xa unit/mL; may administer larger dose for dialysis periods lasting longer than 4 hours. Based on prior results, modify dosage in 500 anti-Xa unit intervals for future dialysis treatments.
Dialysis sessions of more than 4 hours:
Initial IV bolus: 2,250 anti-Xa units. (do not add to dialysis circuit). Dialysis intervals over 4 hours may require a lower second IV dose. In successive dialysis sessions, adjust the dose to reach plasma amounts of 0.2 to 0.4 anti-Xa units/mL.
Mechanical prosthetic heart valve to bridge anticoagulation
Administer 175 anti-Xa units/kg daily once
The dosage may be modified perioperatively based on anti-factor Xa monitoring for high-risk operations and treatments.
Intermittent intravenous injection
8000-10,000 units intravenous initially, following 50-70 units/kg (5000-10,000 units) every 4-6 hours
Continuous intravenous infusion
5000 units intravenous injection, then by continuous intravenous infusion of 20,000-40,000 units/24 hours
Dosing considerations
There are several concentrations available; extreme caution is necessary to prevent a medication error
When heparin is administered with warfarin sodium or dicumarol, a delay of 24 hours after the last subcutaneous dose or 5 hours after the last intravenous dose should be given before blood is collected if a prothrombin time is achieved.
