Ticagrelor

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 brain; 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, Jantoven); 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 (https://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.

Ticagrelor is used to prevent a serious or life-threatening heart attack or stroke, or death in people who have had a heart attack or who have acute coronary syndrome (ACS; blockage of blood flow to the heart). It is also used to prevent blood clots from forming in people who have received coronary stents (metal tubes surgically placed in clogged blood vessels to improve blood flow) to treat ACS. Ticagrelor is used to decrease the risk of a first-time heart attack or stroke in people at risk with coronary artery disease (CAD; reduced blood flow to the heart). It is also used to decrease the risk of another more serious stroke in people who are having a mild to moderate stroke or a transient ischemic attack (TIA; ministroke). 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.

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.

If you are unable to swallow ticagrelor tablets, you may crush the tablet and mix it with water. Drink the mixture immediately, then refill the glass with water and stir and again drink the mixture immediately. If you have a nasogastric (NG) tube, your doctor or pharmacist will explain how to prepare ticagrelor to give through an NG tube.

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, there is also a higher risk that you could develop a blood clot in the stent if you stop taking ticagrelor too soon.

This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.

• tell your doctor and pharmacist what other prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking or plan to take while taking ticagrelor. Your doctor may need to change the doses of your medications or monitor you carefully for side effects.
• the following nonprescription product may interact with ticagrelor: aspirin. Be sure to let your doctor and pharmacist know that you are taking this medication before you start taking ticagrelor. Do not start this medication while taking ticagrelor without discussing with your healthcare provider.

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location — one that is up and away and out of their sight and reach. https://www.upandaway.org

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website (https://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.

In case of overdose, call the poison control helpline at 1-800-222-1222. Information is also available online at https://www.poisonhelp.org/help. If the victim has collapsed, had a seizure, has trouble breathing, or can't be awakened, immediately call emergency services at 911.

Symptoms of overdose may include the following:

• bleeding
• nausea
• vomiting
• diarrhea
• irregular heartbeat

Keep all appointments with your doctor and the laboratory. Your doctor may order certain lab tests to check your body's response to ticagrelor.

Before having any laboratory test, tell your doctor and the laboratory personnel that you are taking ticagrelor.

Do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription.

It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
