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 (5.4) ] • Heparin Resistance [see Warnings and Precautions (5.6) ] • Hypersensitivity Reactions [see Warnings and Precautions (5.7) ] 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. 6.1 Postmarketing 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 Overdose (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 , 5.4) ] 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 (5.7) ] . Episodes of painful, ischemic, and cyanosed limbs been reported with heparin use. 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 injection, venous thrombosis or phlebitis extending from the site of injection, extravasation, and hypervolemia.

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 (5.5) ] • With an uncontrollable active bleeding state [see Warnings and Precautions (5.5) ] , except when treating disseminated intravascular coagulation. • Solutions containing dextrose may be contraindicated in patients with hypersensitivity to corn products. • 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 ) • Solutions containing dextrose may be contraindicated in patients with hypersensitivity to corn products ( 4 )

11 DESCRIPTION Heparin is a heterogeneous group of straight-chain anionic mucopolysaccharides, called glycosaminoglycans having anticoagulant properties. Although others may be present, the main sugars occurring in heparin are: (1) α-L-iduronic acid 2-sulfate, (2) 2-deoxy-2-sulfamino-α-D-glucose 6∙sulfate, (3) β-D-glucuronic acid, (4) 2-acetamido-2-deoxy-α-D-glucose, and (5) α-L-iduronic acid. These sugars are present in decreasing amounts, usually in the order (2)>(1)>(4)>(3)>(5), and are joined by glycosidic linkages, forming polymers of varying sizes. Heparin is strongly acidic because of its content of covalently linked sulfate and carboxylic acid groups. In heparin sodium, the acidic protons of the sulfate units are partially replaced by sodium ions. Structure of Heparin Sodium (representative subunits): Dextrose, USP is chemically designated D-glucose, monohydrate C6H12O6 ∙ H2O, a hexose sugar freely soluble in water. It has the following structural formula: Water for Injection, USP is chemically designated H2O. Intravenous solutions with heparin sodium (derived from porcine intestinal mucosa) are sterile, nonpyrogenic fluids for intravenous administration. Each 100 mL contains heparin sodium 5,000 or 10,000 USP Units; dextrose, hydrous 5 g; citric acid, anhydrous, 51 mg and sodium citrate, dihydrate 334 mg added as buffers; sodium metabisulfite 20 mg added as an antioxidant. Each liter contains electrolytes sodium and citrate in amounts as listed in HOW SUPPLIED/STORAGE AND HANDLING Table. See Table for summary of contents and characteristics of this solution. The potency is determined by a biological assay using a USP reference standard based on units of heparin activity per milligram. The flexible plastic container is fabricated either from a specially formulated nonplasticized, thermoplastic co-polyester (CR3) or from a polyolefin film. Water can permeate from inside the container into the overwrap but not in amounts sufficient to affect the solution significantly. Solutions inside the plastic container also can leach out certain of its chemical components in very small amounts before the expiration period is attained. However, the safety of the plastic has been confirmed by tests in animals according to USP biological standards for plastic containers. Chemical Structure Chemical Structure

Do not use HEPARIN SODIUM IN 5% DEXTROSE INJECTION as a “catheter lock flush” product. Do not admix with other drugs. Do not use plastic containers in series connection. This product should not be infused under pressure. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. Do not administer unless the solution is clear and container is undamaged. Discard unused portion To Open Tear outer wrap and remove solution container. (Use aseptic technique) 1. Close flow control clamp of administration set. 2. Remove cover from outlet port at bottom of container. 3. Insert piercing pin of administration set into port with a twisting motion until the set is firmly seated. NOTE: See full directions on administration set carton. 4. Suspend container from hanger. 5. Squeeze and release drip chamber to establish proper fluid level in chamber. 6. Open flow control clamp and clear air from set. Close clamp. 7. Attach set to venipuncture device. If device is not indwelling, prime and make venipuncture. 8. Regulate rate of administration with flow control clamp. Warning: Do not use flexible container in series connections. 2.2 Laboratory Monitoring for Efficacy and Safety The dosage of heparin sodium should be adjusted according to the patient's coagulation test results. When heparin is given by continuous intravenous infusion, the coagulation time should be determined approximately every 4 hours in the early stages of treatment. When the drug is administered intermittently by intravenous injection, coagulation tests should be performed before each injection during the early stages of treatment and at appropriate intervals thereafter. Dosage is considered adequate when the activated partial thromboplastin time (APTT) is 1.5 to 2 times normal or when the whole blood clotting time is elevated approximately 2.5 to 3 times the control value. Periodic platelet counts, hematocrits, and tests for occult blood in stool are recommended during the entire course of heparin therapy. 2.3 Therapeutic Anticoagulant Effect with Full-Dose Heparin The dosing recommendations in Table 1 are based on clinical experience. Although dosage must be adjusted for the individual patient according to the results of suitable laboratory tests, the following dosage schedules may be used as guidelines: Table 1: Recommended Adult Full-Dose Heparin Regimens for Therapeutic Anticoagulant Effect Method of Administration Frequency Recommended Dose Based on 150 lb. (68 kg) patient. Intermittent Intravenous Injection Initial Dose 10,000 Units, either undiluted or in 50 to 100 mL of 5% Dextrose Injection Every 4 to 6 hours 5,000 to 10,000 Units, either undiluted or in 50 to 100 mL of 5% Dextrose Injection Continuous Intravenous Infusion Initial Dose 5,000 Units by intravenous injection Continuous 20,000 to 40,000 Units/24 hours in 1000 mL of 5% Dextrose Injection 2.4 Pediatric 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 to 100 units/kg (intravenous bolus over 10 minutes) Maintenance Dose Infants: 25 to 30 units/kg/hour; Infants < 2 months have the highest requirements (average 28 units/kg/hour) Children > 1 year of age: 18 to 20 units/kg/hour; Older children may require less heparin, similar to weight-adjusted adult dosage Monitoring Adjust heparin to maintain APTT of 60 to 85 seconds, assuming this reflects an anti-Factor Xa level of 0.35 to 0.70. 2.5 Cardiovascular Surgery Patients undergoing total body perfusion for open-heart surgery should receive an initial dose of not less than 150 units of heparin sodium per kilogram of body weight. Frequently, a dose of 300 units per kilogram is used for procedures estimated to last less than 60 minutes or 400 units per kilogram for those estimated to last longer than 60 minutes. 2.6 Converting to Warfarin To ensure continuous anticoagulation when converting from heparin sodium to warfarin, continue full heparin therapy for several days until the INR (prothrombin time) has reached a stable therapeutic range. Heparin therapy may then be discontinued without tapering [see Drug Interactions (7.4) ] . 2.7 Converting to Oral Anticoagulants other than Warfarin For patients currently receiving intravenous heparin, stop intravenous infusion of heparin sodium immediately after administering the first dose of oral anticoagulant; or for intermittent intravenous administration of heparin sodium, start oral anticoagulant 0 to 2 hours before the time that the next dose of heparin was to have been administered. 2.8 Extracorporeal Dialysis Follow equipment manufacturer's operating directions carefully. A dose of 25 to 30 units/kg followed by an infusion rate of 1,500 to 2,000 units/hour is suggested based on pharmacodynamic data if specific manufacturers' recommendations are not available.

1 INDICATIONS AND USAGE HEPARIN SODIUM IN 5% DEXTROSE INJECTION is indicated for: • Prophylaxis and treatment of venous thrombosis and pulmonary embolism; • Prophylaxis and treatment of thromboembolic complications associated with atrial fibrillation; • Treatment of acute and chronic consumption coagulopathies (disseminated intravascular coagulation); • Prevention of clotting in arterial and cardiac surgery; • Prophylaxis and treatment of peripheral arterial embolism; • Anticoagulant use in blood transfusions, extracorporeal circulation and dialysis procedures. HEPARIN SODIUM IN 5% DEXTROSE INJECTION is indicated for: ( 1 ) • Prophylaxis and treatment of venous thrombosis and pulmonary embolism • Prophylaxis and treatment of thromboembolic complications associated with atrial fibrillation • Treatment of acute and chronic consumption coagulopathies (disseminated intravascular coagulation) • Prevention of clotting in arterial and cardiac surgery • Prophylaxis and treatment of peripheral arterial embolism • Anticoagulant use in blood transfusions, extracorporeal circulation and dialysis procedures

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 1/2 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.

7 DRUG INTERACTIONS Drugs that interfere with coagulation, platelet aggregation or drugs that counteract coagulation may induce bleeding. ( 7 ) 7.1 Oral 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. 7.2 Platelet 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. 7.3 Other Interactions Digitalis, tetracyclines, nicotine, antihistamines, or intravenous nitroglycerine 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. 7.4 Drug/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.

12 CLINICAL PHARMACOLOGY 12.1 Mechanism 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. 12.2 Pharmacodynamics 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. 12.3 Pharmacokinetics 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 0.07 L/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) ].

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 , 5.4) ] . 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 (5.7) , Adverse Reactions (6) ] . 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) ] .

8.5 Geriatric Use There are limited adequate and well-controlled studies in patients 65 years and older. However, 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) ] .

8.4 Pediatric 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) ] .

8.1 Pregnancy Risk Summary There are no available data on HEPARIN SODIUM IN 5% DEXTROSE 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 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 5% DEXTROSE INJECTION to a pregnant woman and possible risks to the fetus when prescribing HEPARIN SODIUM IN 5% DEXTROSE 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.
