Enoxaparin is a medication that belongs to a class of drugs known as low molecular weight heparins. It is primarily used to prevent and treat blood clots, particularly in patients undergoing surgery or those with certain medical conditions that increase the risk of clot formation. Enoxaparin works by inhibiting specific clotting factors in the blood, which helps to reduce the likelihood of clot development. This medication is typically administered through an injection, either under the skin or into a vein. Patients may receive enoxaparin in a hospital setting or at home, depending on their condition. Common side effects can include bleeding, bruising, and pain at the injection site, so monitoring is essential during treatment.
