🩺 Clinical
Heparin is used to: prevent blood clots from forming in people who have certain medical conditions or who are undergoing certain medical procedures. stop the growth of clots that have already formed in the blood vessels. prevent blood clots from forming in catheters (small plastic tubes through which medication can be administered or blood drawn). treat certain types of blood disorders. Heparin is in a class of medications called anticoagulants ('blood thinners'). It works by decreasing the clotting ability of the blood.

⛔ Contraindications ▾
4 CONTRAINDICATIONS The use of heparin sodium is contraindicated in patients: • With history of heparin-induced thrombocytopenia (HIT) (With or Without Thrombosis) [see Warnings and Precautions (5.3) ] • With a known hypersensitivity to heparin or pork products (e.g., anaphylactoid reactions) [see Adverse Reactions (6.1) ] • In whom suitable blood coagulation tests (e.g., the whole blood clotting time, partial thromboplastin time, etc.) cannot be performed at appropriate intervals (this contraindication refers to full-dose heparin; there is usually no need to monitor coagulation parameters in patients receiving low-dose heparin) [see Warnings and Precautions (5.6) ] • With an uncontrollable active bleeding state [see Warnings and Precautions (5.6) ] , except when treating disseminated intravascular coagulation • History of Heparin-induced Thrombocytopenia (HIT) (With or Without Thrombosis) ( 4 ) • Known hypersensitivity to heparin or pork products ( 4 ) • In whom suitable blood coagulation tests cannot be performed at appropriate intervals ( 4 ) • With an uncontrollable active bleeding state, except when treating disseminated intravascular coagulation ( 4 )
⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS • Fatal Medication Errors: Confirm choice of correct strength prior to administration ( 5.1 ) • Hemorrhage: Fatal cases have occurred. Use caution in conditions with increased risk of hemorrhage ( 5.2 ) • HIT (With or Without Thrombosis): Monitor for signs and symptoms and discontinue if indicative of HIT (With or Without Thrombosis) ( 5.3 ) • Monitoring: Blood coagulation tests guide therapy for full-dose heparin. Monitor platelet count and hematocrit in all patients receiving heparin ( 5.6 ) • Hyperkalemia: Measure blood potassium in patients at risk of hyperkalemia before starting heparin therapy and periodically in all patients ( 5.9 )
5.1Fatal Medication Errors Do not use this product as a "catheter lock flush" product. Heparin is supplied in various strengths. Fatal hemorrhages have occurred due to medication errors. Carefully examine all heparin products to confirm the correct container choice prior to administration of the drug.
5.2Hemorrhage Hemorrhage, including fatal events, has occurred in patients receiving heparin sodium. Avoid using heparin in the presence of major bleeding, except when the benefits of heparin therapy outweigh the potential risks. Hemorrhage can occur at virtually any site in patients receiving heparin.
Adrenal hemorrhage (with resultant acute adrenal insufficiency), ovarian hemorrhage, and retroperitoneal hemorrhage have occurred during anticoagulant therapy with heparin [see Adverse Reactions (6.1) ] . A higher incidence of bleeding has been reported in patients, particularly women, over 60 years of age [see Clinical Pharmacology (12.3) ] . These patients may require a lower dose .
An unexplained fall in hematocrit or fall in blood pressure should lead to serious consideration of a hemorrhagic event. Use heparin sodium with caution in disease states in which there is increased risk of hemorrhage, including: • Cardiovascular — Subacute bacterial endocarditis. Severe hypertension. • Surgical — During and immediately following (a) spinal tap or spinal anesthesia or (b) major surgery, especially involving the brain, spinal cord or eye. • Hematologic — Conditions associated with increased bleeding tendencies, such as hemophilia, thrombocytopenia and some vascular purpuras. • Patients with hereditary antithrombin III deficiency receiving concurrent antithrombin III therapy – The anticoagulant effect of heparin is enhanced by concurrent treatment with antithrombin III (human) in patients with hereditary antithrombin III deficiency.
To reduce the risk of bleeding, reduce the heparin dose during concomitant treatment with antithrombin III (human). • Gastrointestinal — Ulcerative lesions and continuous tube drainage of the stomach or small intestine. • Other — Menstruation, liver disease with impaired hemostasis.
5.3Heparin-induced Thrombocytopenia (HIT) (With or Without Thrombosis) HIT is a serious immune-mediated reaction resulting from irreversible aggregation of platelets. HIT may progress to the development of venous and arterial thromboses, a condition known as HIT with thrombosis. Thrombotic events may also be the initial presentation for HIT.
These serious thromboembolic events include deep vein thrombosis, pulmonary embolism, cerebral vein thrombosis, limb ischemia, stroke, myocardial infarction, thrombus formation on a prosthetic cardiac valve, mesenteric thrombosis, renal arterial thrombosis, skin necrosis, gangrene of the extremities that may lead to amputation, and fatal outcomes. Once HIT (with or without thrombosis) is diagnosed or strongly suspected, all heparin sodium sources (including heparin flushes) should be discontinued and an alternative anticoagulant used.
Future use of heparin sodium, especially within 3 to 6 months following the diagnosis of HIT (with or without thrombosis), and while patients test positive for HIT antibodies, should be avoided. Thrombocytopenia of any degree should be monitored closely. If the platelet count falls below 100,000/m…
🤒 Adverse Reactions ▾
6 ADVERSE REACTIONS The following clinically significant adverse reactions are described elsewhere in the labeling: • Fatal Medication Errors [see Warnings and Precautions (5.1) ] • Hemorrhage [see Warnings and Precautions (5.2) ] • Heparin-induced Thrombocytopenia (HIT) (With or Without Thrombosis) [see Warnings and Precautions (5.3) ] • Thrombocytopenia [see Warnings and Precautions (5.5) ] • Heparin Resistance [see Warnings and Precautions (5.7) ] • Hypersensitivity Reactions [see Warnings and Precautions (5.8) ] • Hyperkalemia [see Warnings and Precautions (5.9) ] Most common adverse reactions are hemorrhage, thrombocytopenia, HIT (With or Without Thrombosis), local irritation, hypersensitivity reactions, and elevations of aminotransferase levels.
( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Pfizer Inc. at 1-800-438-1985 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch .
6.1Postmarketing Experience The following adverse reactions have been identified during post-approval use of heparin sodium. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Hemorrhage Hemorrhage is the chief complication that may result from heparin therapy [see Warnings and Precautions (5.2) ].
An overly prolonged clotting time or minor bleeding during therapy can usually be controlled by withdrawing the drug [see Overdosage (10) ] . Gastrointestinal or urinary tract bleeding during anticoagulant therapy may indicate the presence of an underlying occult lesion. Bleeding can occur at any site but certain specific hemorrhagic complications may be difficult to detect: a.
Adrenal hemorrhage, with resultant acute adrenal insufficiency, has occurred during anticoagulant therapy. Therefore, such treatment should be discontinued in patients who develop signs and symptoms of acute adrenal hemorrhage and insufficiency. Initiation of corrective therapy should not depend on laboratory confirmation of the diagnosis, since any delay in an acute situation may result in the patient's death. b.
Ovarian (corpus luteum) hemorrhage developed in a number of women of reproductive age receiving short- or long-term anticoagulant therapy. This complication if unrecognized may be fatal. c. Retroperitoneal hemorrhage.
Thrombocytopenia, Heparin-induced Thrombocytopenia (HIT) (With or Without Thrombosis) and Delayed Onset of HIT (With or Without Thrombosis): [see Warnings and Precautions (5.3 , 5.5 )] Local Irritation Local irritation, erythema, mild pain, hematoma or ulceration may follow deep subcutaneous (intrafat) injection of heparin sodium. These complications are much more common after intramuscular use, and such use is not recommended. Hypersensitivity Generalized hypersensitivity reactions have been reported with chills, fever, and urticaria as the most usual manifestations, and asthma, rhinitis, lacrimation, headache, nausea and vomiting, and anaphylactoid reactions, including shock, occurring more rarely.
Itching and burning, especially on the plantar site of the feet, may occur [see Warnings and Precautions (5.8) ] . Episodes of painful, ischemic, and cyanosed limbs have been reported with heparin use. Metabolism and Nutrition Disorders – Hyperkalemia.
Elevations of Serum Aminotransferases Significant elevations of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels have occurred in a high percentage of patients (and healthy subjects) who have received heparin. Others Osteoporosis following long-term administration of high doses of heparin, cutaneous necrosis after systemic administration, suppression of aldosterone synthesis, delayed transient alopecia, priapism, and rebound hyperlipemia on discontinuation of heparin sodium have also been reported.
Reactions which may occur because of the solution or the technique of administration include febrile response, infection at the site of inje…
🔄 Drug Interactions ▾
7 DRUG INTERACTIONS • Drugs that interfere with coagulation, platelet aggregation or drugs that counteract coagulation may induce bleeding ( 7 ) • Andexanet alfa may reduce the efficacy of heparin when used concomitantly ( 7.3 )
7.1Oral Anticoagulants Heparin sodium may prolong the one-stage prothrombin time. Therefore, when heparin sodium is given with dicumarol or warfarin sodium, a period of at least 5 hours after the last intravenous dose or 24 hours after the last subcutaneous dose should elapse before blood is drawn if a valid prothrombin time is to be obtained.
7.2Platelet Inhibitors Drugs such as acetylsalicylic acid, dextran, phenylbutazone, ibuprofen, indomethacin, dipyridamole, hydroxychloroquine and others that interfere with platelet-aggregation reactions (the main hemostatic defense of heparinized patients) may induce bleeding and should be used with caution in patients receiving heparin sodium.
7.3Unresponsiveness to Heparin With Concomitant Use With Andexanet Alfa Andexanet binds to heparin-bound antithrombin III (ATIII) and may reduce the anticoagulant effect of heparin. Unresponsiveness to unfractionated heparin may lead to serious and life-threatening thrombotic events. Use of andexanet alfa as an antidote for heparin has not been established.
Avoid use of heparin after use of andexanet alfa for the reversal of direct Factor Xa inhibitors (apixaban and rivaroxaban). If anticoagulation is needed, use an alternative anticoagulant to heparin [see Warnings and Precautions (5.4) ] .
7.4Other Interactions Digitalis, tetracyclines, nicotine, or antihistamines, or intravenous nitroglycerin may partially counteract the anticoagulant action of heparin sodium. Intravenous nitroglycerin administered to heparinized patients may result in a decrease of the partial thromboplastin time with subsequent rebound effect upon discontinuation of nitroglycerin. Careful monitoring of partial thromboplastin time and adjustment of heparin dosage are recommended during coadministration of heparin and intravenous nitroglycerin.
7.5Drug/Laboratory Tests Interactions Prothrombin time – Heparin sodium may prolong the one-stage prothrombin time. Therefore, when heparin sodium is given with warfarin, allow a period of at least 5 hours after the last intravenous dose or 24 hours after the last subcutaneous dose of heparin to elapse before blood is drawn to obtain a valid prothrombin time. Hyperaminotransferasemia Significant elevations of aminotransferase AST (SGOT) and ALT (SGPT) levels have occurred in a high percentage of patients (and healthy subjects) who have received heparin.
Since aminotransferase determinations are important in the differential diagnosis of myocardial infarction, liver disease and pulmonary emboli, rises that might be caused by drugs (like heparin) should be interpreted with caution.
👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS
8.1Pregnancy Risk Summary There are no available data on HEPARIN SODIUM IN SODIUM CHLORIDE INJECTION use in pregnant women to inform a drug-associated risk of major birth defects and miscarriage. In published reports, heparin exposure during pregnancy did not show evidence of an increased risk of adverse maternal or fetal outcomes in humans. No teratogenicity, but early embryo-fetal death was observed in animal reproduction studies with administration of heparin sodium to pregnant rats and rabbits during organogenesis at doses up to 10,000 USP Units/kg/day, approximately 10 times the maximum recommended human dose (MRHD) of 40,000 USP Units/24 hours infusion (see Data ) .
Consider the benefits and risks of HEPARIN SODIUM IN SODIUM CHLORIDE INJECTION to a pregnant woman and possible risks to the fetus when prescribing HEPARIN SODIUM IN SODIUM CHLORIDE INJECTION. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a risk of birth defect, loss, or other adverse outcomes.
In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively. Data Human Data The maternal and fetal outcomes associated with uses of heparin via various dosing methods and administration routes during pregnancy have been investigated in numerous studies. These studies generally reported normal deliveries with no maternal or fetal bleeding and no other complications.
Animal Data In a published study conducted in rats and rabbits, pregnant animals received heparin intravenously during organogenesis at a dose of 10,000 USP Units/kg/day, approximately 10 times the maximum human daily dose based on body weight. The number of early resorptions increased in both species. There was no evidence of teratogenic effects.
8.2Lactation Risk Summary There is no information regarding the presence of HEPARIN SODIUM IN SODIUM CHLORIDE INJECTION in human milk, the effects on the breastfed child, or the effects on milk production. Due to its large molecular weight, heparin is not likely to be excreted in human milk, and any heparin in milk would not be orally absorbed by a nursing child. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for HEPARIN SODIUM IN SODIUM CHLORIDE INJECTION and any potential adverse effects on the breastfed child from HEPARIN SODIUM IN SODIUM CHLORIDE INJECTION or from the underlying maternal condition [see Use in Specific Populations (8.4) ] .
8.4Pediatric Use There are no adequate and well-controlled studies on heparin use in pediatric patients. Pediatric dosing recommendations are based on clinical experience [see Dosage and Administration (2.4) ] .
8.5Geriatric Use A higher incidence of bleeding has been reported in patients over 60 years of age, especially women [see Warnings and Precautions (5.2) ] . Lower doses of heparin may be indicated in these patients [see Clinical Pharmacology (12.3) ] .

🧒 Pediatric Use ▾
2.4Pediatric Use There are no adequate and well-controlled studies on heparin use in pediatric patients. Pediatric dosing recommendations are based on clinical experience. In general, the following dosage schedule may be used as a guideline in pediatric patients: Initial Dose 75 units/kg to 100 units/kg (intravenous bolus over 10 minutes) Maintenance Dose Infants: 25 units/kg/hour to 30 units/kg/hour (continuous intravenous infusion); Infants less than 2 months have the highest requirements (average 28 units/kg/hour) Children greater than 1 year of age: 18 units/kg/hour to 20 units/kg/hour (continuous intravenous infusion); Older children may require less heparin, similar to weight-adjusted adult dosage.
Monitoring Adjust heparin to maintain APTT of 60 seconds to 85 seconds, assuming this reflects an anti-Factor Xa level of 0.35 to 0.70.
8.4Pediatric Use There are no adequate and well-controlled studies on heparin use in pediatric patients. Pediatric dosing recommendations are based on clinical experience [see Dosage and Administration (2.4) ] .
🧓 Geriatric Use ▾
8.5Geriatric Use A higher incidence of bleeding has been reported in patients over 60 years of age, especially women [see Warnings and Precautions (5.2) ] . Lower doses of heparin may be indicated in these patients [see Clinical Pharmacology (12.3) ] .
🆘 Overdosage ▾
10 OVERDOSAGE Symptoms Bleeding is the chief sign of heparin overdosage. Nosebleeds, blood in urine or tarry stools may be noted as the first sign of bleeding. Easy bruising or petechial formations may precede frank bleeding.
Treatment Neutralization of heparin effect: When clinical circumstances (bleeding) require reversal of heparinization, protamine sulfate (1% solution) by slow infusion will neutralize heparin sodium. No more than 50 mg should be administered, very slowly in any 10-minute period. Each mg of protamine sulfate neutralizes approximately 100 USP Heparin Units.
The amount of protamine required decreases over time as heparin is metabolized. Although the metabolism of heparin is complex, it may, for the purpose of choosing a protamine dose, be assumed to have a half-life of about ½ hour after intravenous injection. Administration of protamine sulfate can cause severe hypotensive and anaphylactoid reactions.
Because fatal reactions often resembling anaphylaxis have been reported, the drug should be given only when resuscitation techniques and treatment of anaphylactoid shock are readily available. For additional information, the labeling of Protamine Sulfate Injection, USP products should be consulted. Consider contacting the Poison Help line (1-800-222-1222) or a medical toxicologist for additional overdose management recommendations.
🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Heparin inhibits reactions that lead to the clotting of blood and the formation of fibrin clots both in vitro and in vivo . Heparin acts at multiple sites in the normal coagulation system. Small amounts of heparin in combination with antithrombin III (heparin cofactor) can inhibit thrombosis by inactivating activated Factor X and inhibiting the conversion of prothrombin to thrombin.
Once active thrombosis has developed, larger amounts of heparin can inhibit further coagulation by inactivating thrombin and preventing the conversion of fibrinogen to fibrin. Heparin also prevents the formation of a stable fibrin clot by inhibiting the activation of the fibrin stabilizing factor. Heparin does not have fibrinolytic activity; therefore, it will not lyse existing clots.
12.2Pharmacodynamics Bleeding time is usually unaffected by heparin. Clotting time is prolonged by full therapeutic doses of heparin; in most cases it is not measurably affected by low doses of heparin.
12.3Pharmacokinetics Absorption Heparin is not absorbed through gastrointestinal tract and therefore administered via parenteral route. Peak plasma concentration and the onset of action are achieved immediately after intravenous administration. Distribution Heparin is highly bound to antithrombin, fibrinogens, globulins, serum proteases and lipoproteins. The volume of distribution is
0.07L/kg. Elimination Metabolism Heparin does not undergo enzymatic degradation. Excretion Heparin is mainly cleared from the circulation by liver and reticuloendothelial cells mediated uptake into extravascular space.
Heparin undergoes biphasic clearance, a) rapid saturable clearance (zero order process due to binding to proteins, endothelial cells and macrophage) and b) slower first order elimination. The plasma half-life is dose-dependent, and it ranges from 0.5 to 2 h. Specific Populations Geriatric patients Patients over 60 years of age, following similar doses of heparin, may have higher plasma levels of heparin and longer activated partial thromboplastin times (APTTs) compared with patients under 60 years of age [see Use in Specific Populations (8.5) ].
🧬 Mechanism of Action ▾
12.1Mechanism of Action Heparin inhibits reactions that lead to the clotting of blood and the formation of fibrin clots both in vitro and in vivo . Heparin acts at multiple sites in the normal coagulation system. Small amounts of heparin in combination with antithrombin III (heparin cofactor) can inhibit thrombosis by inactivating activated Factor X and inhibiting the conversion of prothrombin to thrombin.
Once active thrombosis has developed, larger amounts of heparin can inhibit further coagulation by inactivating thrombin and preventing the conversion of fibrinogen to fibrin. Heparin also prevents the formation of a stable fibrin clot by inhibiting the activation of the fibrin stabilizing factor. Heparin does not have fibrinolytic activity; therefore, it will not lyse existing clots.

📋 Description ▾
11 DESCRIPTION Heparin is a heterogeneous group of straight-chain anionic mucopolysaccharides, called glycosaminoglycans possessing anticoagulant properties. It is composed of polymers of alternating derivations of α-D-glucosamido ( N -Sulfated O -Sulfated or N -acetylated) and O -sulfated uronic acid (α-L-iduronic acid or β-D-glucoronic acid). Structure of Heparin Sodium (representative subunits): HEPARIN SODIUM IN SODIUM CHLORIDE INJECTION is a sterile preparation of heparin sodium (derived from porcine intestinal mucosa) for intravenous administration.
It contains no bacteriostatic or antimicrobial agent or added buffer. The solution may contain sodium hydroxide and/or hydrochloric acid for pH adjustment. The pH range is 6.1 (5.0 – 7.5) and the osmolarity mOsmol/L (calc.) is 155.
The potency is determined by a biological assay using a USP reference standard based on units of heparin activity per milligram. Each mL of the 50 USP Units per mL preparations contains: 50 USP Units of heparin sodium, 4.5 mg sodium chloride and 0.1 mg edetate disodium, anhydrous added as a stabilizer. Each mL of the 100 USP Units per mL preparations contains: 100 USP Units of heparin sodium, 4.5 mg sodium chloride and 0.1 mg edetate disodium, anhydrous added as a stabilizer. structural formula for heparin
💬 Information for Patients ▾
17 PATIENT COUNSELING INFORMATION Hemorrhage Inform patients that it may take them longer than usual to stop bleeding, that they may bruise and/or bleed more easily when they are treated with heparin, and that they should report any unusual bleeding or bruising to their physician. Hemorrhage can occur at virtually any site in patients receiving heparin. Fatal hemorrhages have occurred [see Warnings and Precautions (5.2) ].
Prior to Surgery Advise patients to inform physicians and dentists that they are receiving heparin before any surgery is scheduled [see Warnings and Precautions (5.2) ] . Heparin-Induced Thrombocytopenia Inform patients of the risk of heparin-induced thrombocytopenia (HIT). HIT may progress to the development of venous and arterial thromboses, a condition known as heparin-induced thrombocytopenia and thrombosis (HITT).
HIT (With or Without Thrombosis) can occur up to several weeks after the discontinuation of heparin therapy [see Warnings and Precautions (5.3 , 5.5 )] . Hypersensitivity Inform patients that generalized hypersensitivity reactions have been reported. Necrosis of the skin has been reported at the site of subcutaneous injection of heparin [see Warnings and Precautions (5.8) , Adverse Reactions (6.1) ] .
Other Medications Because of the risk of hemorrhage, advise patients to inform their physicians and dentists of all medications they are taking, including non-prescription medications, and before starting any new medication [see Drug Interactions (7.2) ] .
