Enoxaparin is an anticoagulant that helps prevent the formation of blood clots otherwise known as deep vein thrombosis that occur in the lungs (pulmonary embolism). Deep vein thrombosis may develop after certain types of surgery or chronic illnesses that cause people to become bedridden.

Enoxaparin can also be used to prevent vascular complications in people with certain types of angina (chest pain) or heart attacks. 

Severe blood clots around the spinal cord can occur if you are taking enoxaparin during a spinal tap or receiving spinal (epidural) anesthesia – particularly if you have a genetic spinal defect, a history of spinal surgery, or recurrent spinal injuries.

In addition, blood clots can also occur if you are taking other medicines such as blood thinners or NSAIDs (ibuprofen, Advil, Aleve, and others). This type of blood clot can cause long-term or permanent paralysis.

Seek immediate medical help if you have symptoms of a spinal cord blood clot such as back pain, numbness, muscle weakness in the lower body, or loss of bladder or bowel control.
