Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit.
Confirm the choice of the correct Heparin Sodium Injection vial prior to administration of the drug to a patient (see WARNINGS, Fatal Medication Errors). The 1 mL vial must not be confused with a “catheter lock flush” vial or other 1 mL vial of inappropriate strength. Confirm that you have selected the correct medication and strength prior to administration of the drug.
When heparin is added to an infusion solution for continuous intravenous administration, the container should be inverted at least six times to ensure adequate mixing and prevent pooling of the heparin in the solution.
Heparin sodium is not effective by oral administration and should be given by intermittent intravenous injection, intravenous infusion, or deep subcutaneous (intrafat, i.e., above the iliac crest or abdominal fat layer) injection. The intramuscular route of administration should be avoided because of the frequent occurrence of hematoma at the injection site.
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 four 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. After deep subcutaneous (intrafat) injections, tests for adequacy of dosage are best performed on samples drawn four to six hours after the injection.
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.
Converting to Oral AnticoagulantWhen an oral anticoagulant of the coumarin or similar type is to be begun in patients already receiving heparin sodium, baseline and subsequent tests of prothrombin activity must be determined at a time when heparin activity is too low to affect the prothrombin time. This is about five hours after the last IV bolus and 24 hours after the last subcutaneous dose. If continuous IV heparin infusion is used, prothrombin time can usually be measured at any time.
In converting from heparin to an oral anticoagulant, the dose of the oral anticoagulant should be the usual initial amount and thereafter prothrombin time should be determined at the usual intervals. To ensure continuous anticoagulation, it is advisable to continue full heparin therapy for several days after the prothrombin time has reached the therapeutic range. Heparin therapy may then be discontinued without tapering.
Therapeutic Anticoagulant Effect with Full-Dose HeparinAlthough 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:
METHOD OF ADMINISTRATION
FREQUENCY
RECOMMENDED
DOSE (based on
150 lb [68 kg] patient)
Deep Subcutaneous (Intrafat) Injection
A different site should be used for each injection to prevent the development of massive hematoma
Initial Dose
5,000 units by IV injection, followed by 10,000 to 20,000 units of a concentrated solution, subcutaneously
Every 8 hours
8,000 to 10,000 units of a concentrated solution
or
Every 12 hours
15,000 to 20,000 units of a concentrated solution
Intermittent Intravenous Injection
Initial Dose
10,000 units, either undiluted or in 50 to 100 mL of 0.9% Sodium Chloride Injection, USP
Every 4
to 6 hours
5,000 to 10,000 units, either undiluted or in 50 to 100 mL of 0.9% Sodium Chloride Injection, USP
Intravenous Infusion
Initial Dose
5,000 units by IV injection
Continuous
20,000 to 40,000 units/24 hours in 1,000 mL of 0.9% Sodium Chloride Injection, USP (or in any compatible solution) for infusion
Pediatric UseUse preservative-free HEPARIN SODIUM INJECTION in neonates and infants (see WARNINGS, Benzyl Alcohol Toxicity and PRECAUTIONS, 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 (IV 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.
Geriatric UsePatients over 60 years of age may require lower doses of heparin.
Surgery of the Heart and Blood VesselsPatients 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 of heparin sodium per kilogram of body weight 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.
Low-Dose Prophylaxis of Postoperative ThromboembolismA number of well-controlled clinical trials have demonstrated that low-dose heparin prophylaxis, given just prior to and after surgery, will reduce the incidence of postoperative deep vein thrombosis in the legs (as measured by the I-125 fibrinogen technique and venography) and of clinical pulmonary embolism. The most widely used dosage has been 5,000 units 2 hours before surgery and 5,000 units every 8 to 12 hours thereafter for seven days or until the patient is fully ambulatory, whichever is longer. The heparin is given by deep subcutaneous injection in the arm or abdomen with a fine needle (25 to 26 gauge) to minimize tissue trauma. A concentrated solution of heparin sodium is recommended. Such prophylaxis should be reserved for patients over the age of 40 who are undergoing major surgery. Patients with bleeding disorders and those having neurosurgery, spinal anesthesia, eye surgery or potentially sanguineous operations should be excluded, as well as patients receiving oral anticoagulants or platelet-active drugs (see WARNINGS). The value of such prophylaxis in hip surgery has not been established. The possibility of increased bleeding during surgery or postoperatively should be borne in mind. If such bleeding occurs, discontinuance of heparin and neutralization with protamine sulfate are advisable. If clinical evidence of thromboembolism develops despite low-dose prophylaxis, full therapeutic doses of anticoagulants should be given unless contraindicated. All patients should be screened prior to heparinization to rule out bleeding disorders, and monitoring should be performed with appropriate coagulation tests just prior to surgery. Coagulation test values should be normal or only slightly elevated. There is usually no need for daily monitoring of the effect of low-dose heparin in patients with normal coagulation parameters.
Extracorporeal DialysisFollow equipment manufacturers’ operating directions carefully.
Blood TransfusionAddition of 400 to 600 USP units per 100 mL of whole blood is usually employed to prevent coagulation. Usually, 7,500 USP units of heparin sodium are added to 100 mL of 0.9% Sodium Chloride Injection, USP (or 75,000 USP units/1,000 mL of 0.9% Sodium Chloride Injection, USP) and mixed; from this sterile solution, 6 to 8 mL are added per 100 mL of whole blood.
Laboratory SamplesAddition of 70 to 150 units of heparin sodium per 10 to 20 mL sample of whole blood is usually employed to prevent coagulation of the sample. Leukocyte counts should be performed on heparinized blood within two hours after addition of the heparin. Heparinized blood should not be used for isoagglutinin, complement, or erythrocyte fragility tests or platelet counts.
Converting to Oral AnticoagulantWhen an oral anticoagulant of the coumarin or similar type is to be begun in patients already receiving heparin sodium, baseline and subsequent tests of prothrombin activity must be determined at a time when heparin activity is too low to affect the prothrombin time.
