10-100 units/m L solution; flush intermittent intravenous catheters after each use with 1-5 m L; for central venous catheters, use 2-3 m L of 10 units/m L solution; for peripheral catheters, use 1-2 m L of 10 units/m L solution.
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.
1-2 hours (dose-dependent; prolonged with higher doses, renal impairment, or in elderly).
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.
No specific dose adjustment required for heparin lock flush; however, monitor for bleeding in severe renal impairment (Cr Cl <30 m L/min) due to potential accumulation.
No specific GFR-based dose adjustment required; monitor a PTT closely in renal impairment due to accumulation risk.
Heparin-induced thrombocytopenia (HIT) with thrombosis; spinal/epidural hematoma risk with neuraxial anesthesia or spinal puncture.
Heparin does not cross the placenta. No evidence of teratogenicity in first trimester. Risk of maternal hemorrhage and fetal complications (e.g., placental abruption) in second and third trimesters due to anticoagulant effects, but drug itself not directly teratogenic. Fetal risk is related to maternal bleeding.
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 lock flush solution is used to maintain patency of intravenous catheters; do not use as a systemic anticoagulant. Flush volume should match catheter dead space. Monitor for signs of bleeding, especially in patients with coagulation disorders. Do not use if solution is discolored or contains particulates. Incompatible with many drugs; avoid mixing in same line.
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 in the liver via desulfation and depolymerization; also cleared by the reticuloendothelial system.
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.
Renal (predominantly via reticuloendothelial system and liver metabolism; unchanged drug excreted in urine).
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 (>95%; primarily to antithrombin III, but also to albumin and other proteins).
High protein binding to antithrombin III (ATIII), albumin, and other proteins; overall ~95% bound.
0.05-0.1 L/kg (confined to plasma; does not cross placenta or blood-brain barrier).
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.
Intravenous: 100% (only route used).
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).
No specific dose adjustment required; use with caution in severe hepatic impairment (Child-Pugh C) due to increased risk of bleeding.
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.
Weight-based: 0.5-2 m L of 10 units/m L solution per flush for intermittent intravenous catheters; maximum 10 units/kg per flush; repeat after each catheter use.
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.
No specific dose adjustment; use lower end of dosing range (1-2 m L of 10 units/m L) due to increased risk of bleeding and renal function decline.
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.
Monitor platelet counts for HIT; risk of hemorrhage; use preservative-free formulation in neonates; caution in renal impairment; monitor a PTT or anti-Xa levels.
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.
Active major bleeding; history of heparin-induced thrombocytopenia; severe thrombocytopenia; hypersensitivity to heparin; not for intramuscular use.
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 known food interactions.
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 its high molecular weight, making it safe for breastfeeding. No M/P ratio is available; use is considered compatible.
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 heparin clearance due to increased blood volume and renal function, potentially requiring higher doses. Monitor a PTT and adjust dose to maintain therapeutic range (typically 1.5-2.5 times control). Dose adjustments are often needed in the second and third trimesters.
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.
