How Does Lovenox Prevent Blood Clots?

Enoxaparin increases the activity of antithrombin, which inhibits clotting factor Xa and, to a lesser degree, factor IIa. This reduces thrombin generation and the formation and extension of blood clots.

Who Is Treated With Lovenox?

Lovenox is used for clot prevention after certain abdominal, hip, or knee procedures and during acute illness with severely restricted mobility. It also treats selected acute deep vein thrombosis and is used for unstable angina, non-Q-wave myocardial infarction, and ST-segment elevation myocardial infarction. Active major bleeding and recent heparin-induced thrombocytopenia are contraindications.

How Is Lovenox Dosed?

Dosing depends on the indication, body weight, kidney function, and care setting. Common adult prevention regimens include 40 mg subcutaneously once daily or 30 mg every 12 hours for certain orthopedic procedures. Acute deep vein thrombosis treatment commonly uses 1 mg per kg every 12 hours or, in selected hospitalized patients, 1.5 mg per kg once daily. Creatinine clearance below 30 mL per minute requires dose adjustment.

What Serious Risks Are Linked to Lovenox?

Lovenox carries a boxed warning for spinal or epidural hematomas during neuraxial anesthesia or spinal puncture, which can cause permanent paralysis. Other serious concerns include major bleeding, heparin-induced thrombocytopenia with or without thrombosis, and increased clotting risk in pregnant patients with mechanical prosthetic heart valves. Blood counts, platelets, kidney function, and signs of bleeding are monitored.
