People using this medication may bleed near the spinal cord after certain spinal procedures. Bleeding in this area can cause paralysis that lasts a long time or could become permanent. Talk with your doctor about the benefits and risks before any spinal procedure. Your doctor may direct you to stop this medication for a certain amount of time before and after the procedure. Carefully follow your doctor's directions.
The risk of bleeding may be higher if you have a deformed spine, or have had spinal procedures/surgery before (such as epidural catheter placement, difficult epidural/spinal puncture), or are taking other drugs that can cause bleeding/bruising (including antiplatelet drugs such as clopidogrel, "blood thinners" such as warfarin/rivaroxaban, nonsteroidal anti-inflammatory drugs-NSAIDs such as ibuprofen). Tell your doctor right away if you notice symptoms such as back pain, leg numbness/tingling/weakness, loss of control of the bowels or bladder (incontinence).
Enoxaparin is used to prevent and treat harmful blood clots. This helps to reduce the risk of a stroke or heart attack. This medication helps keep your blood flowing smoothly by lowering the activity of clotting proteins in the blood. Enoxaparin is an anticoagulant, also known as a "blood thinner." It is a type of heparin.
Conditions which increase your risk of developing blood clots include certain types of surgeries (such as knee/hip replacement, abdominal), long periods of being immobile, certain types of heart attack, and a specific type of chest pain called unstable angina. For some medical conditions, enoxaparin may be used in combination with other "blood thinners."
Read the Patient Information Leaflet if available from your pharmacist before you start using enoxaparin and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

This medication is sometimes used together with other drugs that have "blood thinning" or anti-platelet effects such as aspirin, clopidogrel, or warfarin. When these combinations are prescribed by your doctor, you will require closer monitoring to minimize your risk of bleeding. Keep all medical and laboratory appointments.
Check all prescription and nonprescription medicine labels carefully since many medications contain pain relievers/fever reducers (NSAIDs such as ibuprofen, naproxen, or aspirin) which can increase the risk of bleeding/anti-platelet effect when used with enoxaparin.

Ask your doctor or pharmacist for more details.
