Important: How To Use This Information
This is a summary and does NOT have all possible information about this product. This information does not assure that this product is safe, effective, or appropriate for you. This information is not individual medical advice and does not substitute for the advice of your health care professional. Always ask your health care professional for complete information about this product and your specific health needs.
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."
How To Use
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 given by injection under the skin as directed by your doctor, usually once or twice a day in the abdomen (at least 2 inches from your belly button). Do not inject into a muscle.

This medication may also be given by injection into a vein by a health care professional, as directed by your doctor.

Mild irritation, pain, bruising, redness, and swelling at the injection site may occur. Fatigue or fever may also occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions.

Do not start, stop, or change the dosage of any medicines without your doctor's approval.
A product that may interact with this drug is:
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. However, if your doctor has directed you to take low-dose aspirin for heart attack or stroke prevention (usually at dosages of 81-325 milligrams a day), you should continue taking it unless your doctor instructs you otherwise. Ask your doctor or pharmacist for more details.
If someone has overdosed and has serious symptoms such as passing out or trouble breathing, call 911. Otherwise, call a poison control center right away. US residents can call their local poison control center at 1-800-222-1222. Canada residents can call a provincial poison control center. Symptoms of overdose may include: excessive bleeding and bruising.
Do not share this medication with others.
Laboratory and/or medical tests (such as blood counts including platelets, checking your stool for blood) should be performed periodically to monitor your progress or check for side effects. Additional lab tests (anti-factor Xa blood levels) should be performed in certain cases, especially if you have kidney disease, are pregnant and have artificial heart valves, or to check if enoxaparin is working well for you. Consult your doctor for more details.
If you miss a dose, use it as soon as you remember. If it is near the time of the next dose, skip the missed dose. Use your next dose at the regular time. Do not double the dose to catch up.
