Patient Education

Aspirin and Omeprazole


The combination of aspirin and omeprazole is used to reduce the risk of stroke or heart attack in patients who have had or are at risk of these conditions and are also at risk of developing a stomach ulcer when taking aspirin. Aspirin is in a class of medications called antiplatelet agents. It works by preventing platelets (a type of blood cell) from collecting and forming clots that may cause a heart attack or stroke. Omeprazole is in a class of medications called proton-pump inhibitors. It works by decreasing the amount of acid made in the stomach.

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.
