Patient Education

Enoxaparin Injection


Enoxaparin is used to prevent blood clots in the leg in patients who are on bedrest or who are having hip replacement, knee replacement, or stomach surgery. It is used in combination with aspirin to prevent complications from angina (chest pain) and heart attacks. It is also used in combination with warfarin to treat blood clots in the leg. Enoxaparin is in a class of medications called low molecular weight heparins. It works by stopping the formation of substances that cause clots.

Blood Thinners


Blood thinners are medicines that prevent blood clots from forming. They also keep existing blood clots from getting larger. Clots in your arteries, veins, and heart can cause heart attacks, strokes, and blockages. You may take a blood thinner if you have

There are two main types of blood thinners. Anticoagulants such as heparin or warfarin (also called Coumadin) slow down your body's process of making clots. Antiplatelet drugs, such as aspirin, prevent blood cells called platelets from clumping together to form a clot.

When you take a blood thinner, follow directions carefully. Blood thinners may interact with certain foods, medicines, vitamins, and alcohol. Make sure that your health care provider knows all of the medicines and supplements you are using. You will probably need regular blood tests to check how well your blood is clotting. It is important to make sure that you're taking enough medicine to prevent clots, but not so much that it causes bleeding.
