Intravenous: Initial bolus of 80 units/kg followed by continuous infusion at 18 units/kg/hour; subcutaneous: 5000 units every 8-12 hours.
Loading dose: 5000 units IV bolus, then continuous IV infusion at 12,000-18,000 units/24h (10-15 units/kg/h). Adjust to target a PTT 60-80 seconds.
Terminal elimination half-life: 1-2 hours (0.5-1.5 h at therapeutic doses, dose-dependent due to saturable clearance). Context: shorter half-life in pulmonary embolism, prolonged in hepatic/renal impairment. Protamine reversal used for rapid offset.
The terminal elimination half-life of heparin is dose- and concentration-dependent, averaging 1-2 hours after intravenous administration. At therapeutic doses, the half-life is approximately 1.5 hours; with higher doses, it can extend to 2.5-3 hours. The half-life is prolonged in patients with hepatic or renal impairment.
Cr Cl <30 m L/min: reduce dose by 50% and monitor anti-Xa levels; Cr Cl 30-60 m L/min: reduce dose by 25%; no adjustment for Cr Cl >60 m L/min.
No specific dose adjustment for GFR; however, monitoring a PTT is recommended due to potential accumulation in severe renal impairment (Cr Cl <30 m L/min).
Heparin is contraindicated in patients with a history of heparin-induced thrombocytopenia (HIT) or known hypersensitivity to heparin. Use with extreme caution in patients with major bleeding risk.
Heparin does not cross the placenta. No evidence of teratogenicity in first trimester. Use during second and third trimesters is generally considered safe, but risk of maternal hemorrhage and fetal bleeding exists peripartum.
Heparin does not cross the placenta and is not associated with teratogenicity. First trimester: No increased risk of congenital anomalies. Second and third trimesters: No fetal harm reported; however, increased risk of maternal hemorrhage and osteoporosis with prolonged use.
Liquaemin (heparin sodium) is a parenteral anticoagulant; monitor a PTT closely (goal 1.5-2.5x baseline). Protamine sulfate is the reversal agent. Avoid intramuscular injection due to hematoma risk. Use with caution in renal impairment. Heparin-induced thrombocytopenia (HIT) is a serious adverse effect; check platelet counts regularly.
HEPARIN SODIUM 12,500 UNITS IN DEXTROSE 5% is an IV infusion. Doses are typically weight-based; common starting infusion rates: 18 units/kg/hr for VTE treatment. Monitor a PTT every 6 hours initially, adjust to goal 1.5-2.5x control. Use weight-based nomogram. D5W may cause hyperglycemia in diabetics, consider D5W as vehicle only. Check platelets for HIT (type II). Do not use in patients with active bleeding, HIT history, or epidural catheter. Protamine sulfate 1 mg per 100 units heparin reverses effect.

Their specific mechanisms of action, pharmacokinetic characteristics, and side effects differ.
The maternal-fetal safety profiles of these drugs differ. LIQUAEMIN SODIUM PRESERVATIVE FREE carries a safety status of Category C, whereas HEPARIN SODIUM 12,500 UNITS IN DEXTROSE 5% safety is classified as Category A/B. Consult a board-certified physician or healthcare specialist to establish an accurate, individualized pregnancy risk assessment before starting either therapy.
Heparin is primarily metabolized by the liver via desulfation and depolymerization; renal clearance of inactive metabolites also occurs.
Heparin undergoes partial hepatic metabolism (desulfation) but is primarily cleared by the reticuloendothelial system and excreted in urine as unchanged drug or low molecular weight metabolites.
Renal: 50-70% as unchanged heparin and metabolites via saturable clearance; biliary/fecal: <5% as metabolites.
Heparin is eliminated primarily via the reticuloendothelial system and liver, with renal excretion of metabolites accounting for approximately 50-60% of the dose. A small fraction (up to 5%) is excreted unchanged in urine. No significant biliary or fecal elimination.
High: ~90-95%, primarily to antithrombin III, with secondary binding to albumin, fibrinogen, and histidine-rich glycoprotein.
Heparin is extensively bound to plasma proteins, including antithrombin III (primary), heparin cofactor II, albumin, and lipoproteins. Protein binding is approximately 95-98%, but this is saturable and variable.
0.05-0.07 L/kg (confined to plasma volume; low Vd due to high protein binding and large molecular size).
The apparent volume of distribution (Vd) for heparin is approximately 0.06-0.1 L/kg (limited to plasma volume, ~5-10 L in adults). This reflects its large molecular weight and high protein binding, restricting it to the intravascular space.
Sub Q: 20-30% (due to binding to endothelial cells and macrophages at injection site). IV: 100%.
Subcutaneous: bioavailability is approximately 20-30% due to reduced absorption and first-pass metabolism in the vascular endothelium. Intravenous: 100% bioavailability. No oral bioavailability due to degradation in the gastrointestinal tract.
Child-Pugh Class B or C: reduce initial dose by 50% and monitor anti-Xa; no data for Class A, use with caution.
No specific Child-Pugh based dose adjustments; increased risk of bleeding in hepatic impairment, monitor a PTT closely.
Intravenous: 75-100 units/kg bolus, then 20-25 units/kg/hour infusion; subcutaneous: 250 units/kg every 12 hours. Adjust to maintain a PTT 1.5-2.5 times control.
Loading dose: 75-100 units/kg IV bolus over 10 minutes; maintenance: 25-30 units/kg/h continuous IV infusion, titrated to a PTT 60-85 seconds.
Patients >60 years: reduced clearance; lower initial bolus (60 units/kg) and infusion rate (15 units/kg/hour); monitor a PTT and anti-Xa closely.
Elderly patients may have reduced clearance; consider lower initial infusion rates (10-12 units/kg/h) and monitor a PTT more frequently.
Heparin is not intended for intramuscular (IM) use. Fatal hemorrhages have occurred due to idiosyncratic thrombocytopenia (heparin-induced thrombocytopenia, HIT). For patients with documented HIT or history of HIT, use alternative anticoagulants. Spinal or epidural hematomas can occur with concomitant neuraxial anesthesia, leading to prolonged or permanent paralysis. Monitor for signs and symptoms of neurological impairment.
No direct food interactions; however, foods rich in vitamin K (e.g., leafy greens) do not significantly alter heparin efficacy, but maintain consistent intake if on warfarin transition.
No direct food interactions. Avoid excessive alcohol consumption as it may increase bleeding risk. Consistent vitamin K intake from leafy greens may slightly affect coagulation but is not a concern with heparin as it works via antithrombin III. No specific dietary restrictions.
Heparin is not excreted into breast milk due to high molecular weight and polarity. Considered compatible with breastfeeding. M/P ratio not applicable.
Heparin is not excreted into breast milk due to its high molecular weight and negative charge; therefore, it is considered compatible with breastfeeding. M/P ratio: Not applicable (no detectable levels in milk).
Heparin clearance increases in pregnancy due to expanded plasma volume and renal hyperfiltration, often requiring dose increases (20-30% higher weight-based dosing) and monitoring of anti-Xa levels to maintain therapeutic range.
Pregnancy increases heparin clearance due to expanded plasma volume and increased renal function. Higher doses (often by 20-30%) may be required to achieve therapeutic anti-Xa levels. Monitor anti-Xa levels regularly and adjust dose to maintain target range.
