3 inactive ingredients listed in the exact product block matched to this NDC.

Where does this data come from?
Data sourced from official FDA Structured Product Labeling (SPL) via DailyMedingredient classCode="IACT" elements from the exact product block matched by this NDC. Label-section narrative from DailyMed / the openFDA label index is shown separately when available.

Inactive ingredient FAQ

Are inactive ingredients the same for every manufacturer?
No. Inactive ingredients can differ by manufacturer, dosage form, strength, and package / product version.
Why might an inactive ingredient be missing?
Some SPLs do not provide a complete structured inactive-ingredient list, and older or unusual labels may only include the information in narrative text.
Can inactive ingredients matter?
Yes. They can matter for allergies, intolerances, dyes, gluten / lactose concerns, preservatives, and formulation differences — but confirm with a pharmacist or the manufacturer when it’s clinically important.

💲 Pricing

A drug doesn't have one price. Each row is a different public payment system, and none is what you'd pay at the counter — that depends on your insurance. The ⓘ on each row explains what it measures.

Medicare Part B allowsASP · J1644 $0.199 / J1644 unit
Where does this data come from?
NADAC (National Average Drug Acquisition Cost) is the CMS weekly pharmacy-acquisition-cost survey — what pharmacies pay. ASP (Average Sales Price) is the CMS Medicare Part B drug-payment file, published quarterly. Medicaid pays is computed by us from CMS State Drug Utilization Data (total reimbursed ÷ units, trailing 12 months) — gross of rebates and inclusive of dispensing fees, so it reflects what Medicaid paid, not an acquisition cost. Medicare drug plans pay is the median negotiated point-of-sale unit cost across plans listing this NDC in the CMS quarterly Prescription Drug Plan pricing files, before rebates. The VA pays is the federal contract price (FSS, and the statutory Big 4 ceiling where listed) from the VA National Acquisition Center pharmaceutical price file. All are free public government data; each measures a different payer, so the figures are not directly comparable.

🗺️ Medicaid utilization & spend

📍 This exact package only: Medicaid data is reported per full 11-digit NDC — labeler, product and pack size — so every number here is for 63323-0519-77, not the drug overall. Other pack sizes report separately.
💊 Pharmacy benefit only: These are Medicaid outpatient pharmacy claims, billed by NDC. They exclude the medical benefit — clinic- or hospital-administered drugs billed under HCPCS J-codes — so drugs used mostly that way (e.g. Avastin, Lucentis, Keytruda) can look low or missing here. That’s expected, not an error.
📅 Q1 2025 – Q4 2025 · 4 quarters of data

Medicare Part D (outpatient prescription) spending for Heparin Sodium — the program that covers self-administered drugs. 10 manufacturers.
⚠️ Drug-level data: CMS publishes Part D spending by drug, not by NDC — these figures combine every manufacturer, strength and package size sold under the name Heparin Sodium. That’s a different level of aggregation than the Medicaid card above, which is specific to this exact 11-digit NDC (pack size included), so the two aren’t directly comparable.

Questions about this listing

Why is there no price listed?
The pricing shown on our NDC pages comes from CMS NADAC, a voluntary survey of retail community pharmacy invoices. CMS does not publish a NADAC for every NDC — packages outside the retail survey (institutional and hospital products, bulk packages, discontinued items, and many OTC items) may never receive one. A missing price reflects the survey's scope, not this product's actual cost, and does not mean the product is free or unavailable.
Is the NDC printed on the package the same as the 11-digit billing NDC?
Yes, they identify this exact package in different formats. The FDA registers it as 63323-519-77, which is what is printed on the packaging and shown on DailyMed. Insurance claims use a fixed 11-digit 5-4-2 format, so the short segment is padded with a leading zero: 63323-0519-77, written without dashes as 63323051977. The Identity section at the top of this page lists every form of this code.
What do the three segments of this NDC mean?
In 63323-0519-77, the first segment (63323) is the labeler code FDA assigned to Fresenius Kabi USA, LLC; the middle segment (0519) identifies this specific product — its ingredient, strength, and dosage form; and the last segment (77) identifies this exact package size and type. Together they name one specific package of one specific product.
Is this package still being marketed?
Yes, per the latest FDA NDC Directory data on this page: this package is listed as actively marketed, with no marketing end date reported by Fresenius Kabi USA, LLC. Listing status can change — the directory data on this page refreshes weekly.
Does this product come in other package sizes?
Yes — the FDA directory lists 1 other package presentation of this same product, including 1000 ml (63323-0519-10). Each has its own NDC and its own page — see the package list near the top of this page.
Who lists this product with the FDA?
Fresenius Kabi USA, LLC is the labeler of record for this NDC — the company under whose FDA-assigned code the package is listed. The labeler may be the manufacturer itself or a distributor marketing the product under its own code.
Do I need a prescription for this product?
This NDC is listed with FDA as a prescription product, so it is dispensed under a prescriber's order. Your pharmacist can tell you whether any over-the-counter forms of the same medication exist.
Does this product have a billing J-code?
Yes — this NDC cross-references HCPCS code J1644 for medical-claim billing (typically used when a product is administered in a clinical setting rather than dispensed at a retail pharmacy). See the Billing section on this page.
This page identifies an FDA-listed package (the NDC) and reports public regulatory and pricing data about the listing. It is reference information, not a medical recommendation — talk to your pharmacist or prescriber about your own medication.
Where does this data come from?
Listing facts (marketing category, packager status, marketing dates) from the FDA openFDA NDC Directory; label availability from DailyMed; pricing coverage from CMS NADAC; equivalence scope from the FDA Orange Book.

🎯 Indications and Usage 49 words

1 INDICATIONS AND USAGE Heparin Sodium Injection in Sodium Chloride at a concentration of 2 units/mL is indicated as an anticoagulant to maintain catheter patency. HEPARIN SODIUM IN SODIUM CHLORIDE INJECTION at a concentration of 2 units/mL is indicated as an anticoagulant to maintain catheter patency. ( 1 )

⏱️ Dosage and Administration ~2 min read

2 DOSAGE AND ADMINISTRATION Infuse through intravenous catheter at a rate of 6 units per hour. ( 2.2 )

2.1Preparation for Administration Do not administer unless solution is clear and seal is intact. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. Warning: Do not use plastic containers in series connection.

Such use could result in air embolism due to residual air being drawn from the primary container before administration of the fluid from the secondary container is completed. Do not use Heparin Sodium in Sodium Chloride Injection as a “catheter lock flush” product. Do not admix with other drugs.

Discard unused portion. INSTRUCTIONS FOR USE for the free flex ® Bag Leave bag in the overwrap until time of use. The intact port cap provides visual tamper evidence.

Do not use if port cap is prematurely removed. Maintain strict aseptic technique during handling. To Open: Always inspect the bag before and after removal from the overwrap.

Place the bag on a clean, flat surface. Starting in the bottom corner, peel the overwrap open and remove the bag. Check the bag for leaks by squeezing firmly.

If leaks are found, discard the bag. Do not use if the solution is cloudy or a precipitate is present. To Prepare for Administration: Immediately before connecting the infusion set, firmly grasp the BLUE infusion port cap with the arrow pointing away from the bag between index finger and thumb.

Gently break off the port cap. The membrane of the infusion port is sterile, and disinfection before initial use is not necessary if proper aseptic handling technique is followed. Use a non-vented infusion set or close the air-inlet on a vented set.

The BLUE infusion port is compatible with spike systems produced according to ISO 8536-4, with an external spike diameter of 5.5 to 5.7 mm. Close the roller clamp of the infusion set. Hold the base of the BLUE infusion port and insert the spike by rotating your wrist slightly until the spike is fully inserted.

The port membrane contains a self-sealing septum that helps prevent leakage after removing the spike. The infusion port is not intended to be spiked more than once. Hang from the hole at the top of the bag.

For Single Use Only. Discard unused portion.

2.2Recommended Dosage for Maintenance of Catheter Patency The recommended starting dose is 6 units per hour by intravenous infusion through an intravenous catheter to maintain catheter patency.

💊 Dosage Forms and Strengths 81 words

3 DOSAGE FORMS AND STRENGTHS Injection: 1,000 USP units per 500 mL (2 units per mL) clear solution in a single-dose infusion bag Injection: 2,000 USP units per 1,000 mL (2 units per mL) clear solution in a single-dose infusion bag Injection: 1,000 USP units in Sodium Chloride per 500 mL single-dose infusion bag (2 units per mL) ( 3 ) Injection: 2,000 USP units in Sodium Chloride per 1,000 mL single-dose infusion bag (2 units per mL) ( 3 )

Contraindications 151 words

4 CONTRAINDICATIONS The use of HEPARIN SODIUM IN SODIUM CHLORIDE is contraindicated in patients with the following conditions: Uncontrollable active bleeding state, except when this is due to disseminated intravascular coagulation [see Warnings and Precautions ( 5.1 )] History of heparin-induced thrombocytopenia (HIT) and heparin-induced thrombocytopenia with thrombosis (HITT) [see Warnings and Precautions ( 5.2 )] Severe thrombocytopenia [see Warnings and Precautions ( 5.3 )] Known hypersensitivity to heparin or pork products (e.g., anaphylactoid reactions) [see Warnings and Precautions ( 5.5 ), Adverse Reactions ( 6.1 )] Heparin Sodium in Sodium Chloride Injection is contraindicated in patients with the following conditions: ( 4 ) Uncontrollable active bleeding state, except when this is due to disseminated intravascular coagulation ( 5.1 ) History of heparin-induced thrombocytopenia (HIT) and heparin induced thrombocytopenia with thrombosis ( 5.2 ) Severe thrombocytopenia ( 5.3 ) Known hypersensitivity to heparin or pork products ( 5.5 , 6.1 )

⚠️ Warnings and Cautions ~3 min read

5 WARNINGS AND PRECAUTIONS Hemorrhage: Fatal hemorrhages have occurred. Monitor for signs of bleeding and manage promptly. ( 5.1 ) HIT and HITT: Monitor for signs and symptoms and discontinue if indicative of HIT or HITT.

( 5.2 ) Thrombocytopenia: Monitor platelet count during therapy; discontinue heparin if HIT or HITT is suspected. ( 5.3 ) Heparin Resistance: Increased resistance to heparin is frequently encountered in fever, thrombosis, thrombophlebitis, infections with thrombosing tendencies, myocardial infarction, cancer and in postsurgical patients. ( 5.4 ) Hypersensitivity Reactions: Use in patients with prior reactions only in life threatening situations.

( 5.5 ) Increased Risk of Bleeding in Older Patients, Especially Women: A higher incidence of bleeding has been reported in patients, particularly women, over 60 years of age. ( 5.6 ) Laboratory Tests: Periodic platelet counts, hematocrits, and tests for occult blood in stool are recommended during the entire course of heparin therapy, regardless of the route of administration. ( 5.7 )

5.1Hemorrhage 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. Fatal hemorrhages have occurred.

An unexplained fall in hematocrit or fall in blood pressure, or any other unexplained symptom 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. Gastrointestinal — Ulcerative lesions and continuous tube drainage of the stomach or small intestine.

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). Other — Menstruation, liver disease with impaired hemostasis.

5.2Heparin-Induced Thrombocytopenia and Heparin-Induced Thrombocytopenia with Thrombosis Heparin-induced thrombocytopenia (HIT) is a serious immune-mediated reaction. 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 referred to as heparin-induced thrombocytopenia with thrombosis (HITT). Thrombotic events may also be the initial presentation for HITT.

These serious thromboembolic events include deep vein thrombosis, pulmonary embolism, cerebral vein thrombosis, limb ischemia, stroke, myocardial infarction, mesenteric thrombosis, thrombus formation on a prosthetic cardiac valve, renal arterial thrombosis, skin necrosis, gangrene of the extremities that may lead to amputation, and possibly death. If the platelet count falls below 100,000/mm 3 or if recurrent thrombosis develops, promptly discontinue heparin, evaluate for HIT and HITT, and, if necessary, administer an alternative anticoagulant.

HIT or HITT can occur up to several weeks after the discontinuation of heparin therapy. Patients presenting with thrombocytopenia or thrombosis after discontinuation of heparin sodium should be evaluated for HIT or HITT. HIT can occur up to several weeks after the discontinuation of heparin therapy.

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 ( 5.1 )] .

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 during anticoagulant 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.

HIT and HITT, including delayed onset [see Warnings and Precautions ( 5.2 )] 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 ( 5.5 )]. 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.

7 DRUG INTERACTIONS Drugs that interfere with platelet aggregation or drugs that counteract coagulation may induce bleeding. ( 7 )

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 NSAIDS (including acetylsalicylic acid, ibuprofen, indomethacin, and celecoxib), dextran, phenylbutazone, thienopyridines, dipyridamole, hydroxychloroquine, glycoprotein IIv/IIa antagonists (including abciximab, eptifobatide, 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 the antiplatelet agent or heparin is recommended.

7.3Other Medications that May Interfere with Heparin Digitalis, tetracyclines, nicotine or antihistamines 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).

👥 Use in Specific Populations ~2 min read

8 USE IN SPECIFIC POPULATIONS Geriatric Use: A higher incidence of bleeding has been reported in patients over 60 years of age, especially women ( 5.6 , 8.5 )

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 (see Data ) . Consider the benefits and risks of HEPARIN SODIUM IN SODIUM CHLORIDE INJECTION for the mother 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 background 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 >50 times the human daily dose.

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 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. 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 conditio n [see Use in Specific Populations ( 8.4 )].

8.4Pediatric Use Safety and effectiveness in pediatric patients have not been established.

8.5Geriatric Use A higher incidence of bleeding has been reported in patients over 60 years of age, especially women [see Warnings and Precautions ( 5.1 )].

🆘 Overdosage 140 words

10 OVERDOSAGE Bleeding is the chief sign of heparin overdosage. 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.

Because fatal reactions often resembling anaphylaxis have been reported, protamine sulfate should be given only when resuscitation techniques and treatment of anaphylactoid shock are readily available. For additional information, consult the prescribing information for Protamine Sulfate Injection, USP.

12 CLINICAL PHARMACOLOGY

12.1Mechanism of Action Heparin interacts with the naturally occurring plasma protein, Antithrombin III, to induce a conformational change, which markedly enhances the serine protease activity of Antithrombin II, thereby inhibiting the activated coagulation factors involved in the closing sequence, particularly Xa and IIa. Small amounts of heparin inhibit Factor Xa, and larger amounts inhibit thrombin (Factor IIa). 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 Various times (activated clotting time, activated partial thromboplastin time, prothrombin time, whole blood clotting time) are prolonged by full therapeutic doses of heparin; in most cases, they are not measurably affected by low doses of heparin. Bleeding time is usually unaffected by heparin.

12.3Pharmacokinetics Absorption Heparin is not absorbed through the 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 )] .

📋 Description ~2 min read

11 DESCRIPTION Intravenous solutions with heparin sodium (derived from porcine intestinal mucosa) are sterile, nonpyrogenic fluids for intravenous administration. Each 100 mL contains heparin sodium 200 USP Units; sodium chloride, 0.9 g; citric acid, anhydrous, 37 mg and dibasic sodium phosphate, heptahydrate, 430 mg added as buffers. Each liter contains the following electrolytes: Sodium 186.1 mEq; phosphate (as HPO 4 =) 32.1 mEq; citrate 5.8 mEq; and chloride 153.9 mEq.

Osmolar concentration, 358 mOsmol/liter (calc.); pH 7.0 (5.0 – 7.5). Heparin Sodium, USP 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.

The potency is determined by a biological assay using a USP reference standard based on units of heparin activity per milligram. Structure of Heparin Sodium (representative subunits): Sodium Chloride, USP is chemically designated NaCl, a white crystalline compound freely soluble in water. Dibasic Sodium Phosphate, USP (Heptahydrate), is chemically designated (Na 2 HPO 4 7H 2 O), colorless or white granular salt freely soluble in water.

Citric Acid, USP, anhydrous is chemically designated C 6 H 8 O 7, colorless, translucent crystals or white crystalline powder very soluble in water. It has the following structural formula: Water for Injection, USP is chemically designated H 2 O. The free flex ® container closure system is not made from natural rubber latex, is Non-PVC and Non-DEHP.

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.

💬 Information for Patients ~1 min read

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 ( 5.1 )].

Prior to Surgery Advise patients to inform physicians and dentists that they are receiving heparin before any surgery is scheduled [see Warnings and Precautions ( 5.1 )]. 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 can occur up to several weeks after the discontinuation of heparin therapy [see Warnings and Precautions ( 5.2 )]. 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 ( 5.5 ), 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 ) ].
