Ticagrelor may cause serious or life-threatening bleeding. Tell your doctor if you currently have or have had a condition that causes you to bleed more easily than normal, if you have recently had surgery or been injured in any way, or if you have or have ever had a stomach ulcer; bleeding in your stomach, intestines, or head; a stroke or mini-stroke; a condition that may cause bleeding in your intestines such as polyps (abnormal growths in the lining of the large intestine); or liver disease. Tell your doctor and pharmacist if you are taking medications that may cause bleeding including anticoagulants (blood thinners) such as warfarin (Coumadin); heparin; other medications to treat or prevent blood clots; or regular use of non-steroidal anti-inflammatory medications such as ibuprofen (Advil, Motrin) and naproxen (Aleve). Your doctor also will probably not prescribe ticagrelor if you are likely to need heart bypass surgery (a certain type of open heart surgery) right away. While you are taking ticagrelor, you will probably bruise and bleed more easily than usual or bleed for longer than usual and may be more likely to have nosebleeds. However, if you experience any of the following symptoms, call your doctor immediately: bleeding that is unexplained, severe, long-lasting, or uncontrollable; pink or brown urine; red or black, tarry stools; vomit that is bloody or that looks like coffee grounds; or coughing up blood or blood clots.
If you are having surgery, including dental surgery, or any type of medical procedure, tell your doctor or dentist that you are taking ticagrelor. Your doctor will probably tell you to stop taking ticagrelor at least 5 days before your surgery is scheduled.
Your doctor will probably tell you to take a low dose of aspirin (less than 100 mg) during your treatment, but taking higher doses of aspirin may prevent ticagrelor from working as it should. Many over-the-counter (OTC) medications contain aspirin, so be sure to read all labels carefully. Do not take additional aspirin or aspirin-containing products during your treatment with ticagrelor without talking to your doctor.
Your doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when you begin treatment with ticagrelor and each time you refill your prescription. Read the information carefully and ask your doctor or pharmacist if you have any questions. You can also visit the Food and Drug Administration (FDA) website (http://www.fda.gov/Drugs/DrugSafety/ucm085729.htm) or the manufacturer's website to obtain the Medication Guide.
Talk to your doctor about the risks of taking ticagrelor.
Why is this medication prescribed?
Ticagrelor is used along with aspirin to prevent serious problems with the heart and blood vessels in people who have had a heart attack or severe chest pain. Ticagrelor is in a class of medications called antiplatelet medications. It works by preventing platelets (a type of blood cell) from collecting and forming clots that may cause a heart attack or stroke.
How should this medicine be used?
Ticagrelor comes as a tablet to take by mouth. It is usually taken with or without food two times a day. Take ticagrelor at around the same times 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 ticagrelor exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Ticagrelor will help prevent serious problems with your heart and blood vessels only as long as you take the medication. Continue to take ticagrelor even if you feel well. Do not stop taking ticagrelor without talking to your doctor. If you stop taking ticagrelor, there is a higher risk that you may have a heart attack or stroke. If you have a stent (small tube placed in an artery to improve blood flow), there is also a higher risk that you could develop a blood clot in the stent if you stop taking ticagrelor too soon.
