Ticagrelor may cause serious (sometimes fatal) bleeding. Before taking this medication, tell your doctor your medical history, especially about any bleeding problems. Also, before having any surgery, tell your doctor or dentist about all the products you use, especially ticagrelor. Your doctor or dentist will give you specific directions for when to stop taking this medication before your surgery. See also Precautions section.
This medication is usually taken with low-dose aspirin, usually 75-100 milligrams once a day. Unless otherwise directed by your doctor, do not take more than 100 milligrams of aspirin daily. Doing so may make ticagrelor work less well. Ask your doctor or pharmacist for details.
Ticagrelor is used along with low-dose aspirin to help prevent heart attack and stroke in people with heart problems (such as unstable angina, previous heart attack). It may also be used to prevent heart attack or stroke after certain heart surgeries (such as stent placement, coronary artery bypass graft-CABG, or angioplasty).
Ticagrelor works by blocking platelets from sticking together and prevents them from forming harmful clots. It is an antiplatelet drug. It keeps blood flowing smoothly in your body.
Read the Medication Guide provided by your pharmacist before you start taking ticagrelor and each time you get a refill. If you have any questions, ask your doctor or pharmacist.
Take this medication by mouth with or without food as directed by your doctor, usually twice daily. Take a low-dose aspirin (usually 75-100 milligrams) once a day as directed by your doctor. Follow your doctor's directions carefully. See also Warning section.
If you have trouble swallowing ticagrelor, you may crush the tablet. Mix the crushed tablet with water in a glass, then drink the mixture right away. Refill the glass with water, stir, and drink to make sure you take all of your dose.

Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions. Keep a list of all the products you use (including prescription/nonprescription drugs and herbal products) and share it with your doctor and pharmacist. Do not start, stop, or change the dosage of any medicines without your doctor's approval.
Some products that may interact with this drug include: mifepristone, other drugs that can cause bleeding/bruising (including other antiplatelet drugs such as clopidogrel, NSAIDs such as ibuprofen/naproxen, "blood thinners" such as dabigatran/warfarin).
Other medications can affect the removal of ticagrelor from your body, which may affect how ticagrelor works. Examples include dexamethasone, nefazodone, azole antifungals (such as itraconazole, ketoconazole), HIV protease inhibitors (such as atazanavir, ritonavir), hepatitis C virus protease inhibitors (such as boceprevir, telaprevir), macrolide antibiotics (such as clarithromycin), rifamycins (such as rifampin), drugs used to treat seizures (such as carbamazepine, phenytoin), telithromycin, among others.
Check all prescription and nonprescription medicine labels carefully since many medications contain pain relievers/fever reducers (aspirin, NSAIDs such as ibuprofen or naproxen). These drugs are similar to ticagrelor and may increase your risk of side effects if taken together. However, if your doctor has directed you to take low-dose aspirin to prevent heart attack or stroke (usually at dosages of 75-100 milligrams a day), you should continue taking the aspirin unless your doctor instructs you otherwise. Ask your doctor or pharmacist for more details.
