Why is this medication prescribed?
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.
How should this medicine be used?
The combination of aspirin and omeprazole comes as a delayed-release tablet (releases the medication in the intestine to prevent damage to the stomach) to take by mouth. It is usually taken once daily with liquid at least 60 minutes before a meal. Take the combination of aspirin and omeprazole at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take the combination of aspirin and omeprazole exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Swallow the delayed-release tablets whole; do not split, dissolve, chew, or crush them.
Continue to take aspirin and omeprazole even if you feel well. Do not stop taking aspirin and omeprazole without talking to your doctor. If you stop taking aspirin and omeprazole, there is a higher risk that you may have a heart attack or stroke.
Do not take the combination of aspirin and omeprazole to treat sudden signs and symptoms of a heart attack or stroke.
Ask your pharmacist or doctor for a copy of the manufacturer's information for the patient.
