Enoxaparin (Enoxaparin sodium) — Uses, Dosage, Side Effects & Safety

Drug class: Low Molecular Weight Heparin (LMWH)

Overview

Enoxaparin is a type of anticoagulant, commonly known as a 'blood thinner.' It is used to prevent and treat blood clots in the veins, lungs, or heart. This includes conditions such as deep vein thrombosis (DVT), pulmonary embolism (PE), and to reduce the risk of clotting during certain surgeries or in people who are bedridden. Enoxaparin works by blocking specific clotting factors in your blood, making it less likely for dangerous clots to form. It is usually given as an injection under the skin. Patients should know that while enoxaparin helps prevent harmful clots, it can also increase the risk of bleeding. Always follow your healthcare provider’s instructions carefully.
