Precautions & Cautions
While taking this drug, you may experience easier bleeding, so it is crucial to be cautious and avoid injuries. To minimize the risk of bleeding, use a soft toothbrush and an electric razor for shaving.
There is a risk of severe and potentially life-threatening bleeding problems associated with this medication. Additionally, this drug can cause a condition known as heparin-induced thrombocytopenia (HIT), which may lead to the formation of blood clots, also referred to as heparin-induced thrombocytopenia and thrombosis (HITTS). Both HIT and HITTS can be fatal or cause other complications, and they may occur up to several weeks after stopping the medication. If you have any questions or concerns, discuss them with your doctor. It is also important to undergo blood tests as directed by your doctor and to consult with your doctor regarding any concerns.
This medication may interfere with certain laboratory tests, so it is vital to inform all your healthcare providers and laboratory personnel that you are taking this drug.
If you experience a fall, injury, or head trauma, contact your doctor immediately, even if you feel fine.
Ensure that you have the correct product, as this medication is available in various containers and strengths. If you are unsure, consult your doctor or pharmacist.
If you have a sulfite allergy, inform your doctor, as some products may contain sulfites.
Individuals over 60 years old should use this medication with caution, as they may be more susceptible to side effects.
Some products contain benzyl alcohol, which can cause serious side effects in newborns and infants, particularly when combined with other medications containing benzyl alcohol. Consult your doctor to determine if the product you are using contains benzyl alcohol and to discuss potential risks.
If you are pregnant, plan to become pregnant, or are breastfeeding, inform your doctor to discuss the potential benefits and risks to you and your baby.
Overdose Information
Overdose Symptoms:
- Excessive bleeding (e.g., hematuria, melena, epistaxis, ecchymoses, petechiae)
- Significant drop in blood pressure or heart rate due to blood loss
- Signs of internal hemorrhage (e.g., severe abdominal pain, headache, altered mental status)
What to Do:
Immediately discontinue heparin. The antidote for heparin overdose is protamine sulfate. Call 911 or your local emergency number. For non-emergency advice, call a poison control center (e.g., 1-800-222-1222 in the US).
Drug Interactions
Contraindicated Interactions
- Patients with active major bleeding
- History of Heparin-Induced Thrombocytopenia (HIT)
- Severe thrombocytopenia
- Uncontrolled active hemorrhage
- Recent brain, spinal, or eye surgery
- Lumbar puncture or regional anesthetic procedures (epidural/spinal anesthesia) in patients receiving therapeutic anticoagulation
Major Interactions
- Other anticoagulants (e.g., warfarin, dabigatran, rivaroxaban, apixaban, edoxaban): Increased risk of bleeding.
- Antiplatelet agents (e.g., aspirin, clopidogrel, prasugrel, ticagrelor, NSAIDs): Increased risk of bleeding.
- Thrombolytic agents (e.g., alteplase, tenecteplase): Increased risk of bleeding.
- Dextran: Increased risk of bleeding.
Moderate Interactions
- Corticosteroids (long-term use): May increase bleeding risk.
- Nitroglycerin (IV): May decrease heparin effect (monitor aPTT).
- Probenecid: May increase heparin effect.
- Cephalosporins (certain, e.g., cefoperazone, cefotetan): May increase bleeding risk due to vitamin K antagonism.
Minor Interactions
- Not available
Monitoring
Baseline Monitoring
Rationale: To establish baseline platelet count and assess for anemia or other hematologic abnormalities before initiating therapy. Essential for monitoring for Heparin-Induced Thrombocytopenia (HIT).
Timing: Prior to initiation of therapy.
Rationale: To establish baseline coagulation status. Used for monitoring therapeutic heparin dosing.
Timing: Prior to initiation of therapy.
Rationale: To establish baseline coagulation status, especially if transitioning to warfarin or assessing for other coagulopathies.
Timing: Prior to initiation of therapy.
Rationale: To assess organ function, as severe impairment may affect heparin clearance or increase bleeding risk.
Timing: Prior to initiation of therapy.
Routine Monitoring
Frequency: Every 4-6 hours after initiation or dose change for continuous IV infusion, until two consecutive values are in therapeutic range. Then daily.
Target: Typically 1.5-2.5 times the control value (specific range depends on laboratory and indication).
Action Threshold: Adjust infusion rate based on aPTT results to maintain target range. If too high, hold infusion and/or administer protamine sulfate; if too low, increase infusion rate and/or administer bolus.
Frequency: Alternative to aPTT, especially in conditions affecting aPTT (e.g., lupus anticoagulant). Frequency similar to aPTT.
Target: 0.3-0.7 units/mL for therapeutic anticoagulation.
Action Threshold: Adjust infusion rate based on anti-Xa results.
Frequency: Every 2-3 days from day 4 to day 14 of therapy, or until heparin is discontinued, to monitor for Heparin-Induced Thrombocytopenia (HIT).
Target: Maintain above 100,000/mm³ or no significant drop from baseline.
Action Threshold: If platelet count drops by >50% from baseline or falls below 100,000/mm³, immediately discontinue heparin and evaluate for HIT.
Frequency: Continuously
Target: Absence of bleeding
Action Threshold: Any signs of bleeding (e.g., hematuria, melena, epistaxis, petechiae, ecchymoses, significant drop in hemoglobin/hematocrit) require immediate assessment and potential intervention.
Symptom Monitoring
- Unusual bleeding or bruising (e.g., nosebleeds, gum bleeding, blood in urine or stool, excessive bruising)
- Petechiae (small red spots on skin)
- Ecchymoses (large bruises)
- Signs of internal bleeding (e.g., severe headache, abdominal pain, weakness, dizziness, pallor)
- Signs of Heparin-Induced Thrombocytopenia (HIT): new or worsening thrombosis, skin lesions at injection site, acute systemic reactions after heparin administration.
Special Patient Groups
Pregnancy
Heparin is often the anticoagulant of choice during pregnancy because it does not cross the placenta and therefore does not cause fetal anticoagulation or teratogenicity. However, it carries risks of maternal bleeding and osteoporosis.
Trimester-Specific Risks:
Lactation
Heparin is considered safe during breastfeeding. It is a large molecule and is not excreted into breast milk in clinically significant amounts.
Pediatric Use
Dosing is weight-based and requires careful titration and monitoring of aPTT or anti-Xa levels due to differences in pharmacokinetics and pharmacodynamics compared to adults. Higher doses per kg may be required in neonates and infants.
Geriatric Use
Increased risk of bleeding due to age-related physiological changes (e.g., decreased renal function, increased capillary fragility, concomitant medications). Lower doses or more frequent monitoring may be necessary.
Clinical Information
Clinical Pearls
- Heparin-Induced Thrombocytopenia (HIT) is a serious, immune-mediated complication. Monitor platelet counts closely (every 2-3 days from day 4 to 14 or until discontinued). If HIT is suspected, immediately discontinue heparin and initiate an alternative non-heparin anticoagulant.
- Protamine sulfate is the specific antidote for heparin overdose. 1 mg of protamine neutralizes approximately 100 units of heparin.
- Heparin is highly acidic and incompatible with many other drugs; always check compatibility before mixing.
- Subcutaneous injections should be given in the abdominal fat, at least 2 inches from the navel, and sites should be rotated to prevent hematoma formation.
- For therapeutic IV infusions, a dedicated IV line is preferred to ensure accurate dosing and minimize interactions.
- Heparin's half-life is dose-dependent, meaning higher doses are cleared more slowly.
Alternative Therapies
- Low Molecular Weight Heparins (LMWH) (e.g., enoxaparin, dalteparin): For DVT/PE prophylaxis and treatment, ACS. Offer more predictable pharmacokinetics and once- or twice-daily dosing.
- Direct Oral Anticoagulants (DOACs) (e.g., dabigatran, rivaroxaban, apixaban, edoxaban): For DVT/PE treatment and prevention of stroke in non-valvular AF. Not suitable for all indications where heparin is used (e.g., acute MI, ECMO).
- Warfarin: Oral anticoagulant for long-term anticoagulation, requires INR monitoring.
- Fondaparinux: Synthetic pentasaccharide, selectively inhibits Factor Xa via ATIII, used for DVT/PE prophylaxis and treatment.
