What is ticagrelor?
Ticagrelor helps to prevent platelets in your blood from sticking together and forming a blood clot. An unwanted blood clot can occur with certain heart or blood vessel conditions.
Ticagrelor is used to lower your risk of having a stroke or serious heart problems after you have had a heart attack or severe chest pain (angina).
Ticagrelor may also be used for purposes not listed in this medication guide.
You should not use ticagrelor if you have severe liver disease, any active bleeding (including a bleeding stomach ulcer), or a history of bleeding in the brain. Do not use this medicine just before heart bypass surgery (coronary artery bypass graft, or CABG).
You may need to stop using ticagrelor for a short time before having surgery or dental work, to prevent excessive bleeding. Do not stop taking ticagrelor without first talking to your doctor, even if you have signs of bleeding. Stopping ticagrelor may increase your risk of a heart attack or stroke.
Ticagrelor may cause you to bleed more easily, which can be severe or life-threatening. Avoid activities that may increase your risk of bleeding or injury.
Call your doctor or seek emergency medical attention if you have bleeding that will not stop. You may also have bleeding on the inside of your body, such as in your stomach or intestines. Call your doctor at once if you have black or bloody stools, red or pink urine, or if you cough up blood or vomit that looks like coffee grounds. These could be signs of bleeding in your digestive tract.
Many drugs (including some over-the-counter medicines and herbal products) can cause serious medical problems if you take them with ticagrelor. It is very important to tell your doctor about all medicines you have recently used.

How should I take ticagrelor?
Follow all directions on your prescription label. Do not take this medicine in larger or smaller amounts or for longer than recommended.
Ticagrelor should be taken together with aspirin. Follow your doctor's instructions about how much aspirin you should take.
Do not take more aspirin than your doctor has prescribed. Taking too much aspirin can make ticagrelor less effective.
Ticagrelor can be taken with or without food. Take the medicine at the same time each day.
Because ticagrelor keeps your blood from coagulating (clotting), this medicine can also make it easier for you to bleed, even from a minor injury. Contact your doctor or seek emergency medical attention if you have any bleeding that will not stop.
Any doctor, dentist, surgeon, or other medical care provider who treats you should know that you are taking ticagrelor. You may need to stop using the medicine for a short time before having surgery or dental work, to prevent excessive bleeding. Follow your doctor's instructions and start taking ticagrelor again as soon as possible.
Do not stop taking ticagrelor without first talking to your doctor, even if you have signs of bleeding. Use ticagrelor regularly to get the most benefit. Get your prescription refilled before you run out of medicine completely. Stopping ticagrelor may increase your risk of a heart attack or stroke.
Store at room temperature away from moisture and heat.
What happens if I miss a dose?
Take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.
What should I avoid while taking ticagrelor?
While you are taking ticagrelor, do not take NSAIDs (nonsteroidal anti-inflammatory drugs) without your doctor's advice. NSAIDs include ibuprofen (Advil, Motrin), naproxen (Aleve), celecoxib (Celebrex), diclofenac, indomethacin, meloxicam, and others.
Avoid activities that may increase your risk of bleeding or injury. Use extra care to prevent bleeding while shaving or brushing your teeth.
Avoid drinking alcohol. It may increase your risk of bleeding in your stomach or intestines.
Ask a doctor or pharmacist before using any cold, allergy, pain, or sleep medication. Aspirin (sometimes abbreviated as ASA) is contained in many combination medicines. Taking certain products together can cause you to get too much aspirin which can increase your risk of bleeding. Check the label to see if a medicine contains aspirin or ASA.
