Ticagrelor isn't suitable for some people. To make sure this medicine is safe for you, tell your doctor if you:
- have had an allergic reaction to ticagrelor or any other medicines in the past
- have any injuries that are currently bleeding a lot, such as a wound
- have a stomach ulcer

When you start taking ticagrelor, you'll take 1 dose on your first day.
After this, most people take ticagrelor twice a day, usually once in the morning and once in the evening.
You can take ticagrelor with or without food.
If you're taking melt in the mouth tablets, put the tablet on your tongue and let it dissolve. You can then swallow it with or without water.
How much to take and how long for
Ticagrelor comes as 90mg tablets. It's also available as 60mg tablets for people who need a lower dose.
On your first day of treatment, your pharmacist will give you two 90mg tablets to take at the same time. After this, the usual dose is 90mg twice a day for 12 months.
If you have had a heart attack, your doctor may advise you to keep on taking ticagrelor after you have finished the 12-month course of treatment.
You'll usually take a lower dose of 60mg, twice a day, for up to 3 years.
What if I forget to take it?
If you forget to take ticagrelor, take it as soon as you remember. If it's nearly time for your next dose, skip the missed dose.
Do not take a double dose to make up for a forgotten dose.
If you often forget doses, it may help to set an alarm to remind you.
You could also ask your pharmacist for advice on other ways to help you remember to take your medicine.
If you're worried, contact your doctor or pharmacist.
What if I take too much?
Accidentally taking 1 or 2 extra tablets is unlikely to harm you.
But the amount of ticagrelor that can lead to overdose is different for everyone.
Contact your doctor straight away if you have taken some extra tablets and notice any signs of bleeding.
Like all medicines, ticagrelor can cause side effects, although not everyone gets them.
Common side effects
These common side effects happen in more than 1 in 100 people.
Talk to your doctor or pharmacist if these side effects bother you or don't go away:
- bleeding more easily than normal - nosebleeds, bruising or bleeding that takes longer to stop
- unexpected shortness of breath while resting - this can sometimes happen in the first few weeks of taking ticagrelor and is usually mild
- pain and swelling in your joints - these can be signs of gout (this is because ticagrelor can lead to high levels of uric acid in your blood)
- feeling sick or indigestion
- diarrhoea or constipation
- mild rash
Serious side effects
Serious side effects are rare and happen in less than 1 in 1,000 people.
Tell a doctor straight away if you:
- are coughing up blood, or there's blood in your pee, poo or vomit - this needs to be checked out as these are signs of internal bleeding
- get weakness on one side of your body, trouble speaking or thinking, loss of balance or blurred eyesight - these can be signs of a stroke
If you suspect that you or someone else is having a stroke, phone 999 immediately and ask for an ambulance.
Serious allergic reaction
In rare cases, ticagrelor can cause a serious allergic reaction (anaphylaxis).
Call 999 or go to A&E if:
- you get a skin rash that may include itchy, red, swollen, blistered or peeling skin
- you're wheezing
- you get tightness in the chest or throat
- you have trouble breathing or talking
- your mouth, face, lips, tongue or throat start swelling
You could be having a serious allergic reaction and may need immediate treatment in hospital.
These are not all the side effects of ticagrelor. For a full list, see the leaflet inside your medicines packet.
You can report any suspected side effect to the UK safety scheme.
- bleeding more easily than normal - be careful when doing activities that might cause an injury or a cut. Always wear a helmet when cycling. Wear gloves when you use sharp objects like scissors, knives, and gardening tools. Use an electric razor instead of wet shaving, and use a soft toothbrush and waxed dental floss to clean your teeth. See a doctor if you're worried about any bleeding.
- shortness of breath - try breathing in slowly through your nose and out through your mouth. Sitting on a chair and leaning your chest slightly forward may also help. Your breathing will usually return to normal within a few weeks of starting ticagrelor. Tell your doctor if your symptoms don't improve or get worse. Shortness of breath can also be a sign of an ongoing or worsening heart problem.
- pain and swelling in your joints - if you get unusual muscle pain, weakness or tiredness which isn't from exercise or hard work, talk to your doctor. You may need a blood test to check what might be causing it.
- headaches - make sure you rest and drink plenty of fluids, but do not drink too much alcohol. Ask your pharmacist to recommend a painkiller. If your headaches last longer than a week or are severe, talk to your doctor.
- dizziness - if ticagrelor makes you feel dizzy when you stand up, try getting up very slowly or stay sitting down until you feel better. If you begin to feel dizzy, lie down so that you don't faint, then sit until you feel better. Do not drive or use any tools or machinery if you're dizzy, have muscle cramps or muscle pain, or are feeling a bit shaky.
- feeling sick or indigestion - try taking your tablets with a meal or snack, or shortly after eating. It may also help if you avoid eating rich or spicy food. If you have indigestion that doesn't go away, it could be a sign that you have a stomach ulcer. Talk to your doctor - they may prescribe something to protect your stomach or switch you to a different medicine.
- diarrhoea or constipation - drink plenty of water or other fluids if you have diarrhoea. Speak to a pharmacist if you have signs of dehydration, such as peeing less than usual or having dark, strong-smelling pee. Do not take any other medicines to treat diarrhoea without speaking to a pharmacist or doctor. If you have constipation, get more fibre into your diet, such as fresh fruit, vegetables and cereals, and drink plenty of water. Try to exercise, for example, by going for a daily walk or run. If this doesn't help, talk to your pharmacist or doctor.
- mild rash - it may help to take an antihistamine, which you can buy from a pharmacy. Check with the pharmacist to see what type is suitable for you.
Ticagrelor isn't recommended during pregnancy or if you're trying to get pregnant.
To avoid getting pregnant, make sure you use contraception while you're taking ticagrelor.
But if you're trying to get pregnant, talk to your doctor, who may be able to recommend a medicine more suitable for you.
If you're breastfeeding, talk to your doctor before taking ticagrelor.
Your doctor will be able to explain the benefits and risks of taking ticagrelor while breastfeeding, and will recommend the most suitable treatment for you and your baby.
Tell your doctor if you're:
- trying to get pregnant
Some medicines interfere with the way ticagrelor works.
Tell your doctor if you're taking these medicines before you start taking ticagrelor:
- medicines to thin blood or prevent blood clots, such as aspirin and warfarin
- rivaroxaban or apixaban
- non-steroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen
- antidepressants called selective serotonin reuptake inhibitors (SSRIs), such as citalopram
- some antibiotics, such as clarithromycin and rifampicin
- medicines for epilepsy, such as phenytoin and carbamazepine
- statins, such as simvastatin, used to lower cholesterol
- digoxin for heart problems
Taking ticagrelor with everyday painkillers
Your doctor may prescribe low dose aspirin (75mg tablets) to take together with ticagrelor.
You can take paracetamol together with ticagrelor.
Mixing ticagrelor with herbal remedies and supplements
There might be a problem with taking some herbal remedies and supplements with ticagrelor, especially ones that can affect your blood (for example, ginkgo).
St John's wort (used for depression) can reduce the levels of ticagrelor in your blood. This may stop ticagrelor from working properly and increase your chances of getting a blood clot.
Tell your doctor or pharmacist if you're taking any other medicines, including herbal remedies, vitamins or supplements.
How does ticagrelor work?
Ticagrelor slows the blood's clotting action by making platelets less sticky.
Platelets are blood cells that stick together and block any cuts and breaks in blood vessels.
The clot can stop blood flowing to the heart or brain and cause a heart attack or stroke.
If you take it every day, ticagrelor stops platelets from clumping together to form unwanted blood clots, and prevents heart attacks and strokes.
How long does it take to work?
Ticagrelor works within 30 minutes of taking your first dose of two 90mg tablets.
You may not feel any different after you start taking ticagrelor. This doesn't mean that the medicine isn't working.
Carry on taking it even if you feel well, as you'll still be getting the benefits.
When will I feel better?
You may not notice any difference in how you feel after you start taking ticagrelor. This doesn't mean that the medicine isn't working.
Carry on taking ticagrelor, even if you feel well. You'll still be getting the benefits.
How long will I take it for?
You'll usually need to take ticagrelor for up to 12 months.
Your doctor may want you to continue taking it after the 12-month course has finished.
If so, you'll take ticagrelor at a lower dose of 60mg a day for up to 3 years.
Is it safe to take it for a long time?
Ticagrelor is generally safe to take for a long time. In fact, it works best if you take it for many months, or even years.
If you're at risk of getting a stomach ulcer, your doctor may prescribe a medicine to help protect your stomach while you're taking ticagrelor.
What will happen if I stop taking it?
Do not stop taking ticagrelor without talking to your doctor.
If you stop taking ticagrelor, the rate at which your blood clots will return to what it was before you started taking it, usually within 3 days of stopping.
This means you may be at increased risk of serious problems like heart attacks or strokes.
Are there any other similar medicines?
Not all medicines that prevent blood clots are suitable for everyone.
Talk to your doctor or pharmacist to find out why you have been recommended a particular medicine.
How does ticagrelor compare with other antiplatelet medicines like clopidogrel?
Ticagrelor works just as well as clopidogrel for:
- preventing blood clots
- preventing future heart attacks if you have already had a heart attack
But ticagrelor is not approved for preventing further strokes if you have already had a stroke.
In this case, your doctor may prescribe clopidogrel instead.
You'll usually take clopidogrel once a day, while ticagrelor is taken twice a day.
Clopidogrel may be less likely to cause bleeding than ticagrelor.
Can I drink alcohol with it?
Yes, you can drink alcohol while taking ticagrelor as long as you stick to the national guidelines of no more than 14 units a week for men and women.
A standard glass of wine (175ml) is 2 units. A pint of lager or beer is usually 2 to 3 units of alcohol.
Drinking too much alcohol while you're taking ticagrelor can irritate your stomach. This can increase your risk of getting a stomach ulcer.
Is there any food or drink I need to avoid?
Do not drink grapefruit juice while taking ticagrelor. Grapefruit juice may increase the blood-thinning effect of your medicine.
Can I take indigestion medicines at the same time?
Ticagrelor can be taken at the same time as indigestion medicines.
Your pharmacist will be able to recommend a suitable indigestion remedy for you.
Will I need to stop ticagrelor before having surgery or dental treatment?
Because of the risk of bleeding, you may need to stop taking ticagrelor for a short time before having surgery or dental work.
Do not stop taking ticagrelor without first talking to your doctor or dentist. They'll tell you if you need to stop taking ticagrelor before a procedure.
Can I have vaccinations?
Yes, you can have vaccinations while taking ticagrelor.
It's a good idea to mention to the doctor or nurse that you're taking a blood thinner.
Will it affect my contraception or fertility?
Will it affect my fertility?
There's no firm evidence to suggest that taking ticagrelor will reduce fertility in either men or women.
Will it affect my sex life?
Ticagrelor will not affect your sex life.
But some women may notice vaginal bleeding that's heavier than, or happens at different times to, their normal period.
Speak to your doctor if you're worried, or if you have postmenopausal bleeding.
Can I drive or ride a bike?
Most people can drive or cycle while taking ticagrelor.
But if ticagrelor makes you feel dizzy, do not drive a car or ride a bike until this goes away.
Can lifestyle changes help?
If you have been prescribed ticagrelor, you can also boost your health by making some key lifestyle changes.
- Quit smoking - smoking increases your heart rate and blood pressure. Quitting smoking will cut your risk of heart attack and stroke. Try to avoid secondhand smoke, too.
- Cut down on alcohol - try to keep to the recommended guidelines of no more than 14 units of alcohol a week. A standard glass of wine (175ml) is 2 units. A pint of lager or beer is usually 2 to 3 units of alcohol.
- Exercise - regular exercise keeps your heart and blood vessels in good condition. It doesn't need to be too energetic: walking every day is enough.
- Eat well - aim to eat a diet that includes plenty of fruit and veg, wholegrains, fat-free or low-fat dairy products, and lean proteins. It's a good idea to cut down on salt, too. Aim for no more than 6g of salt a day.
- Deal with stress - when you're anxious or upset, your heart beats faster, you breathe more heavily, and your blood pressure often goes up. This raises your risk of heart attack and stroke. Find ways to reduce stress in your life. To give your heart a rest, try napping or putting your feet up when possible. Spend time with friends and family to be social and help keep stress at bay.
- Vaccinations - if you have heart disease, it's recommended that you have a flu jab every year and a pneumonia vaccination (also called the pneumococcal vaccine) every 5 years. Ask your doctor about these vaccinations. You can have them free on the NHS.
