Primary Medical Uses
Thromboembolic Disorders: Used in hospitals to treat and prevent deep vein thrombosis (DVT) in the legs and pulmonary embolisms (PE) in the lungs. [1, 2]
Acute Cardiovascular Care: Administered during the initial management of heart attacks and unstable angina. [1, 2]
Extracorporeal Circulation: Prevents blood from clotting inside machines during open-heart surgery, blood transfusions, or hemodialysis. [1, 2]
Critical Clinical Information
Administration Routes: This specific concentration is typically packaged in a 5 mL vial (yielding 5,000 IU/mL). It is administered intravenously (IV)—either as a bolus or a continuous infusion—or via subcutaneous injection. It must never be injected intramuscularly (IM) due to the high risk of causing large, painful hematomas. [1, 2, 3, 4, 5]
Monitoring: Therapeutic use requires rigorous tracking via blood tests, most commonly the activated partial thromboplastin time (aPTT) or Anti-Xa levels, to ensure the blood is at an optimal thickness. [1, 2]
Reversal Agent: If an accidental overdose or severe bleeding occurs, its anticoagulant effects can be rapidly neutralized by a specific antidote called protamine sulfate. [1, 2]
Safety Warnings & Contraindications
Major Contraindications: It should not be used if you have active, uncontrolled bleeding, a history of Heparin-Induced Thrombocytopenia (HIT—a dangerous drop in platelets caused by previous heparin use), or severe liver disease. [1, 2]
Drug Interactions: Medications like aspirin, ibuprofen, naproxen, or other nonsteroidal anti-inflammatory drugs (NSAIDs) can exponentially increase bleeding risks and should be avoided unless explicitly directed by your physician. [1, 2]
Emergency Symptoms: Seek immediate medical care if you observe red or dark tarry stools, blood in your urine, frequent nosebleeds, or extreme bruising. [1, 2]
