Overdose Information
Overdose Symptoms:
- Excessive bleeding (e.g., epistaxis, hematuria, melena, ecchymoses, hematomas)
- Hypotension
- Tachycardia
- Signs of shock
What to Do:
Immediately discontinue heparin. The effects of heparin can be rapidly neutralized by intravenous administration of protamine sulfate. The dose of protamine sulfate depends on the amount of heparin to be neutralized and the time since heparin administration. Call 1-800-222-1222 (Poison Control) or seek immediate medical attention.
Drug Interactions
Contraindicated Interactions
- History of Heparin-Induced Thrombocytopenia (HIT)
- Active major bleeding
- Severe thrombocytopenia
- Uncontrolled hypertension
- Recent brain, spinal, or eye surgery
- Bacterial endocarditis
Major Interactions
- Other anticoagulants (e.g., warfarin, dabigatran, rivaroxaban, apixaban, edoxaban) - increased risk of bleeding
- Antiplatelet agents (e.g., aspirin, clopidogrel, prasugrel, ticagrelor) - increased risk of bleeding
- NSAIDs (e.g., ibuprofen, naproxen, celecoxib) - increased risk of bleeding
- Thrombolytic agents (e.g., alteplase, tenecteplase) - greatly increased risk of bleeding
- Dextran - increased risk of bleeding
Moderate Interactions
- Certain antibiotics (e.g., penicillins, cephalosporins) - may affect platelet function or gut flora, potentially increasing bleeding risk
- Nitroglycerin (IV) - may decrease heparin effect (monitor aPTT)
- Herbal supplements (e.g., ginkgo biloba, garlic, ginger, dong quai) - may increase bleeding risk
- SSRIs/SNRIs - may increase bleeding risk
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 and for subsequent therapeutic monitoring of heparin's anticoagulant effect.
Timing: Prior to initiation of therapy.
Rationale: To establish baseline coagulation status and rule out pre-existing coagulopathy.
Timing: Prior to initiation of therapy.
Rationale: To assess organ function that may influence drug clearance or bleeding risk.
Timing: Prior to initiation of therapy.
Routine Monitoring
Frequency: Every 4-6 hours after initiation or dose change until therapeutic range is achieved, then at least daily for continuous IV infusion. For SC prophylaxis, not routinely monitored.
Target: Typically 1.5-2.5 times the control value (or specific target range based on anti-Xa levels, e.g., 60-85 seconds), depending on the assay and clinical indication.
Action Threshold: Adjust infusion rate based on aPTT results to maintain target range. If below range, increase dose; if above range, decrease dose or hold.
Frequency: Every 2-3 days (or daily in high-risk patients) from day 4 to day 14 of therapy, or until heparin is discontinued.
Target: Maintain above 100,000/mm³ or no more than 50% drop from baseline.
Action Threshold: If platelet count drops by >50% from baseline or falls below 100,000/mm³, suspect HIT and discontinue heparin immediately, initiate alternative anticoagulant, and test for HIT antibodies.
Frequency: Continuously throughout therapy.
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 dose reduction or discontinuation of heparin.
Symptom Monitoring
- Unusual bleeding or bruising (e.g., nosebleeds, gum bleeding, blood in urine or stool, excessive bruising)
- Petechiae (small red or purple spots on the skin)
- Signs of internal bleeding (e.g., severe headache, abdominal pain, weakness, dizziness, black tarry stools, red or dark urine)
- Signs of Heparin-Induced Thrombocytopenia (HIT): new or worsening thrombosis, skin lesions at injection sites, acute systemic reactions after heparin administration, sudden drop in platelet count (>50% from baseline or <100,000/mm³)
Special Patient Groups
Pregnancy
Heparin is generally considered the anticoagulant of choice during pregnancy because it does not cross the placenta and therefore does not cause fetal anticoagulation or teratogenic effects. It is used for the treatment and prevention of venous thromboembolism (VTE) in pregnant women. However, maternal risks include bleeding, osteoporosis (with long-term use), and heparin-induced thrombocytopenia (HIT).
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. It is not absorbed orally by the infant.
Pediatric Use
Heparin can be used safely in pediatric patients, including neonates, infants, children, and adolescents, for various thrombotic conditions. 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. Neonates and infants may require higher doses per kg due to higher antithrombin levels and faster clearance.
Geriatric Use
Elderly patients (≥65 years) may have an increased risk of bleeding with heparin therapy, particularly those with impaired renal function or multiple comorbidities. Lower initial doses or more conservative dosing strategies may be considered, and close monitoring for bleeding complications is essential.
Clinical Information
Clinical Pearls
- Heparin's anticoagulant effect is highly variable among individuals, necessitating careful laboratory monitoring (aPTT or anti-Xa levels) and dose titration.
- Heparin-Induced Thrombocytopenia (HIT) is a serious, immune-mediated complication characterized by a significant drop in platelet count (typically >50% from baseline) and a paradoxical increase in thrombotic risk. It usually occurs 5-10 days after initiation of heparin. Discontinue heparin immediately if HIT is suspected and initiate alternative non-heparin anticoagulation.
- Protamine sulfate is the specific antidote for heparin overdose. 1 mg of protamine sulfate neutralizes approximately 100 units of heparin.
- Heparin is not absorbed orally and must be administered parenterally (IV or SC).
- Subcutaneous heparin for prophylaxis should not be rubbed after injection, as this can increase bruising.
- Heparin can cause hyperkalemia by inhibiting aldosterone secretion, especially in patients with renal impairment or those on potassium-sparing diuretics.
- Avoid intramuscular injection of heparin due to the high risk of hematoma formation.
Alternative Therapies
- Low Molecular Weight Heparins (LMWH) (e.g., enoxaparin, dalteparin): Often preferred for prophylaxis and outpatient treatment due to more predictable pharmacokinetics, once-daily dosing, and lower incidence of HIT.
- Direct Oral Anticoagulants (DOACs) (e.g., dabigatran, rivaroxaban, apixaban, edoxaban): Used for DVT/PE treatment and prevention, and stroke prevention in atrial fibrillation. Offer oral administration and do not require routine monitoring.
- Warfarin: Oral vitamin K antagonist, used for long-term anticoagulation. Requires regular INR monitoring.
- Fondaparinux: Synthetic pentasaccharide, selectively inhibits Factor Xa via ATIII. Used for DVT/PE prophylaxis and treatment, and in patients with a history of HIT.
