2 DOSAGE AND ADMINISTRATION Recommended Adult Dosages: Therapeutic Anticoagulant Effect with Full-Dose Heparin* ( 2.3 ) Intermittent Intravenous Injection Initial Dose 10,000 Units Subsequent Doses 5,000 to 10,000 Units every 4 to 6 hours Continuous Intravenous Infusion Initial Dose 5,000 Units by intravenous injection Continuous 20,000 to 40,000 Units every 24 hours * Based on 150 lb. (68 kg) patient. Cardiovascular Surgery ( 2.5 ) Intravascular via Total Body Perfusion Initial Dose Greater than or equal to 150 units/kg; adjust for longer procedures Extracorporeal Dialysis ( 2.8 ) Intravascular via Extracorporeal Dialysis Follow equipment manufacturer's operating directions carefully. For pediatric dosing see section 2.4 of full prescribing information. 2.1 Preparation for Administration Confirm the selection of the correct formulation and strength prior to administration of the drug. This product should be administered by intravenous infusion. Do not use Heparin Sodium in 5% Dextrose Injection as a “catheter lock flush” product. Do not admix with other drugs. Discard unused portion. 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. Use only if solution is clear and container and seals are intact. 2.2 Laboratory Monitoring for Efficacy and Safety Adjust the dosage of heparin sodium according to the patient’s coagulation test results. When heparin is given by continuous intravenous infusion, determine the coagulation time approximately every 4 hours in the early stages of treatment. When the drug is administered intermittently by intravenous injection, perform coagulation tests 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 the 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 Subsequent Doses 5,000 to 10,000 Units every 4 to 6 hours Continuous Intravenous Infusion Initial Dose 5,000 Units by intravenous injection Continuous 20,000 to 40,000 Units every 24 hours 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 units/kg to 100 units/kg (intravenous bolus over 10 minutes) Maintenance Dose Infants: 25 units/kg/hour to 30 units/kg/hour; Infants < 2 months have the highest requirements (average 28 units/kg/hour) Children > 1 year of age: 18 units/kg/hour 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…

5 WARNINGS AND PRECAUTIONS Fatal Medication Errors: Confirm choice of correct strength prior to administration. ( 5.1 ) Hemorrhage: Fatal cases have occurred. Monitor for signs of bleeding and manage promptly. ( 5.2 ) HIT or HITT: Monitor for signs and symptoms and discontinue if indicative of HIT or HITT. ( 5.3 ) Thrombocytopenia: Monitor platelet count during therapy; discontinue heparin in HIT or HITT is suspected. ( 5.4 ) Monitoring: Blood coagulation tests guide therapy for full-dose heparin. Monitor platelet count and hematocrit in all patients receiving heparin. ( 5.5 ) Heparin Resistance: Increased resistance to heparin is frequently encountered in fever, thrombosis, thrombophlebitis, infections with thrombosing tendencies, myocardial infarction, cancer and in postsurgical patients. ( 5.6 ) Hypersensitivity Reactions: Use in patients with prior reactions only in life-threatening situations. ( 5.7 ) Hyperkalemia: Measure plasma potassium in patients at risk of hyperkalemia before starting heparin therapy and periodically in all patients ( 5.8 ) Elevations of serum aminotransferases: Interpret elevation of these enzymes with caution. ( 5.9 ) 5.1 Fatal 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. 5.2 Hemorrhage 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) ] . 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. 5.3 Heparin-Induced Thrombocytopenia (HIT) and Heparin-Induced Thrombocytopenia and Thrombosis (HITT) HIT is a serious immune-mediated reaction resulting from irreversible aggregation of platelets. HIT occurs in patients treated with heparin and is due to the development of antibodies to a platelet Factor 4-heparin complex that induce in vivo platelet aggregation. HIT may progress to the development of venous and arterial thromboses, a condition known as HITT. 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…

4 CONTRAINDICATIONS The use of HEPARIN SODIUM in 5% Dextrose Injection is contraindicated in patients with the following conditions: History of heparin-induced thrombocytopenia (HIT) and heparin-induced thrombocytopenia and thrombosis (HITT) [see Warnings and Precautions (5.3) ] Known hypersensitivity to heparin or pork products (e.g., anaphylactoid reactions) [see Warnings and Precautions (5.7) and 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) ] Uncontrollable active bleeding state except when this is due to disseminated intravascular coagulation [see Warnings and Precautions (5.2) ] History of heparin-induced thrombocytopenia (HIT) or heparin-induced thrombocytopenia and thrombosis (HITT) ( 5.3 ) Known hypersensitivity to heparin or pork products ( 5.7 ) In whom suitable blood coagulation tests cannot be performed at appropriate intervals ( 5.5 ) Uncontrollable active bleeding state, except when this is due to disseminated intravascular coagulation ( 5.2 )

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 NSAIDS (including acetylsalicylic acid, ibuprofen, indomethacin, and celecoxib), dextran, phenylbutazone, thienopyridines, dipyridamole, hydroxychloroquine, glycoprotein IIv/IIa antagonists (including abciximab, eptifibatide, and tirofiban), 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. To reduce the risk of bleeding, a reduction in the dose of antiplatelet agent or heparin is recommended. 7.3 Other Medications that May Interfere with Heparin Digitalis, tetracyclines, nicotine, 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. Antithrombin III (human) – 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, a reduced dosage of heparin is recommended during treatment with antithrombin III (human).

6 ADVERSE REACTIONS The following serious adverse reactions are described elsewhere in the labeling: Hemorrhage [see Warnings and Precautions (5.2) ] Heparin-Induced Thrombocytopenia and Heparin-Induced Thrombocytopenia with Thrombosis [see Warnings and Precautions (5.3) ] Thrombocytopenia [see Warnings and Precautions (5.4) ] Heparin Resistance [see Warnings and Precautions (5.6) ] Hypersensitivity [see Warnings and Precautions (5.7) ] Hyperkalemia [see Warnings and Precautions (5.8) ] Elevations of Serum Aminotransferases [see Warnings and Precautions (5.9) ] Most common adverse reactions are: hemorrhage, thrombocytopenia, HIT or HITT, heparin resistance, hypersensitivity reactions, hyperkalemia, and elevations of aminotransferase levels. ( 6 ) To report SUSPECTED ADVERSE REACTIONS, contact B. Braun Medical Inc. at 1-800-227-2862 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. 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: Adrenal hemorrhage, with resultant acute adrenal insufficiency, has occurred with heparin therapy, including fatal cases. Ovarian (corpus luteum) hemorrhage developed in a number of women of reproductive age receiving short- or long-term anticoagulant therapy. Retroperitoneal hemorrhage. Vascular Disorders – Contusion, Vasospastic reactions (including episodes of painful, ischemic, and cyanosed limbs). HIT and HITT, including delayed onset cases, and Thrombocytopenia – [see Warnings and Precautions ( 5.3 and 5.4 )] Histamine-like reactions – Such reactions have been observed at the site of injections. Necrosis of the skin has been reported at the site of subcutaneous injection of heparin, occasionally requiring skin grafting. 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 )] . Musculoskeletal, Connective Tissue and Bone Disorders – Osteoporosis with long-term administration of heparin. Metabolism and Nutrition Disorders – Hyperkalemia. General Disorders and Administration Site Conditions – Erythema, mild pain, ulceration. Elevations of serum aminotransferases – Significant elevations of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels have occurred in patients 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.
