Initial adult dose: 5,000 units IV bolus, followed by continuous IV infusion at 1,000–2,000 units/hour; or 10,000–20,000 units subcutaneously every 12 hours. Dose adjusted based on a PTT.
Continuous IV infusion: Initial bolus 80 units/kg, then 18 units/kg/hour; subsequent dose adjusted based on a PTT. Typical infusion rate: 20,000–40,000 units/24 hours.
Mean 1.5 hours (range 1-2 hours) after IV administration; increases with dose (e.g., 25,000 U IV: ~2.5 h). Clinical context: nonlinear pharmacokinetics; half-life prolonged in hepatic or renal impairment.
Terminal elimination half-life is 1-2 hours at therapeutic doses, dose-dependent: 30-60 min after IV bolus of 25 U/kg, increasing to 1.5-2.5 hours after 400 U/kg. Prolonged in hepatic/renal impairment and pulmonary embolism. Clinical context: continuous infusion achieves steady-state after ~4-6 hours.
GFR <30 m L/min: reduce dose by 25–50% and monitor a PTT closely. GFR 30–60 m L/min: consider dose reduction of 25%. Hemodialysis: avoid or use with extreme caution.
No specific GFR-based dose adjustment required; monitor a PTT closely in renal impairment due to accumulation risk.
Heparin is not intended for intramuscular use. Risk of spinal/epidural hematoma in patients receiving neuraxial anesthesia or spinal puncture, especially with concomitant use of agents affecting hemostasis.
FDA Pregnancy Category B. Heparin does not cross the placenta and is not associated with teratogenicity. First trimester: No increased risk of major birth defects. Second/third trimester: Risk of maternal bleeding complications, fetal hemorrhage, and preterm labor. Use only if clearly needed.
Heparin does not cross the placenta and is not associated with teratogenic effects. No increased risk of fetal malformations has been observed in any trimester.
Heparin (LIQUAEMIN SODIUM) is a parenteral anticoagulant. Monitor a PTT regularly; therapeutic range typically 1.5-2.5 times control. Use cautiously in renal impairment; avoid in severe thrombocytopenia (HIT). Protamine sulfate reverses effect. For subcutaneous administration, use abdominal site to minimize hematoma. Do not use in patients with active bleeding or history of HIT. Check platelet counts frequently.
HEPARIN SODIUM 12,500 UNITS IN DEXTROSE 5% IN PLASTIC CONTAINER is a fixed-concentration heparin solution (125 units/m L) for continuous IV infusion. Dextrose 5% provides free water but minimal calories; monitor serum glucose in diabetics. Confirm patency of IV line and avoid simultaneous infusion with other drugs due to incompatibilities. Use a dedicated IV line. For weight-based dosing, standard concentration is often 100 units/m L; this 125 units/m L may require dose verification. Monitor a PTT every 6 hours initially and adjust infusion rate per nomogram. Do not use if solution is precipitate or colored.

Primarily metabolized by the reticuloendothelial system; partially desulfated and depolymerized. Renal excretion of metabolites.
Primarily cleared by the reticuloendothelial system and metabolized in the liver via desulfation and depolymerization; partially renally excreted as unchanged drug. Metabolism is saturable and dose-dependent.
Primarily renal (heparin is metabolized and excreted as uroheparin and other metabolites; up to 50% of administered dose appears in urine as unchanged heparin, but clearance is dose-dependent and nonlinear).
Heparin is eliminated primarily via hepatic metabolism and renal excretion. Approximately 50% of a dose undergoes hepatic desulfation and depolymerization to form uroheparin, which is excreted in urine. Unchanged heparin is cleared renally via saturable, dose-dependent mechanisms. Biliary/fecal elimination is negligible (<5%).
Very high; primarily binds to antithrombin III, fibrinogen, and other plasma proteins; fraction bound >90%.
High protein binding to antithrombin III (ATIII), albumin, and other proteins; overall ~95% bound.
0.06-0.1 L/kg (confined to plasma volume; does not distribute widely due to high protein binding and polarity).
0.05-0.07 L/kg (confined to plasma volume). Distribution is limited due to high protein binding and large molecular weight; does not cross placenta or blood-brain barrier.
SC: variable, ~30% (due to first-pass metabolism and binding; highly dependent on injection site and depth).
SC: ~30% (variable due to binding to endothelial cells and macrophages). IV: 100%. IM: not recommended. Oral: negligible (<1% due to GI degradation and large molecular size).
Child-Pugh class B or C: dose reduction of 25–50% recommended due to increased risk of bleeding; monitor a PTT and anti-Xa levels.
Child-Pugh A: No adjustment. Child-Pugh B or C: Reduce dose by 25–50% and monitor a PTT frequently due to decreased anticoagulant factors.
Neonates: 75 units/kg IV bolus, then 20 units/kg/hour. Infants and children: initial bolus 50–100 units/kg, maintenance 15–25 units/kg/hour continuous infusion; titrate to a PTT 1.5–2.5 times control.
IV bolus: 75–100 units/kg; maintenance: 20 units/kg/hour continuous infusion; adjust to target a PTT (e.g., 60–85 seconds). Monitor closely.
Elderly patients: initial dose reduction of 25–50% due to decreased renal function and higher bleeding risk; monitor a PTT and anti-Xa levels frequently.
Initial bolus and infusion rates at lower end of range; consider 50 units/kg bolus and 15 units/kg/hour due to increased bleeding risk and reduced clearance.
Spinal/epidural hematoma risk in patients receiving neuraxial anesthesia or spinal puncture: Use of anticoagulants, including heparin, increases risk of spinal or epidural hematoma resulting in long-term or permanent paralysis. Monitor for signs/symptoms of neurological impairment and treat urgently.
Risk of hemorrhage; heparin-induced thrombocytopenia (HIT); hypersensitivity reactions; hyperkalemia due to aldosterone suppression; osteoporosis with prolonged use; caution in renal/hepatic impairment, obesity, elderly; monitor platelet counts and a PTT.
Hemorrhage: Major bleeding risk; monitor a PTT and adjust dose. Heparin-induced thrombocytopenia (HIT): Monitor platelet counts; discontinue if HIT suspected. Osteoporosis: Long-term use associated with bone loss. Hyperkalemia: Due to aldosterone suppression. Preservative-free formulation required for neonates/infants to avoid benzyl alcohol toxicity.
Hypersensitivity to heparin; uncontrolled bleeding; history of HIT; severe thrombocytopenia; suspected intracranial hemorrhage; inability to perform adequate coagulation monitoring.
Active major bleeding or bleeding disorders (e.g., hemophilia, thrombocytopenia), history of heparin-induced thrombocytopenia (HIT), severe uncontrolled hypertension, recent surgery of eye/brain/spinal cord, known hypersensitivity to heparin or pork products, and inability to perform adequate coagulation monitoring.
No significant food interactions are known. However, foods rich in vitamin K (e.g., leafy greens) may theoretically affect coagulation, but heparin's action is not vitamin K-dependent. Advise consistent intake of vitamin K-rich foods if also on warfarin. No specific dietary restrictions required.
No direct food interactions with heparin. However, avoid excessive consumption of vitamin K-rich foods (e.g., leafy greens) if transitioning to warfarin, but this is not relevant during heparin infusion.
Heparin is not excreted into breast milk due to high molecular weight and protein binding. Considered compatible with breastfeeding. M/P ratio: Not applicable (no transfer).
Heparin is not excreted into breast milk due to its high molecular weight and poor oral bioavailability; therefore, it is considered compatible with breastfeeding. M/P ratio is not applicable.
Pregnancy increases volume of distribution and renal clearance, potentially requiring higher doses of unfractionated heparin to achieve therapeutic a PTT; monitor anti-Xa levels and adjust accordingly. Dose requirements may increase by 20-50% in the second and third trimesters. Postpartum, doses should be reduced to prepregnancy levels.
Pregnancy is associated with increased plasma volume, renal clearance, and heparin-binding proteins, which may reduce heparin efficacy. Dose adjustments are often required; monitor a PTT regularly and adjust dose to maintain therapeutic anticoagulation. Higher doses may be needed in the second and third trimesters.
