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've finished the 12-month course of treatment. You'll usually take a lower dose of 60mg, twice a day, for up to 3 years.

How and when to take ticagrelor

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.

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 and take your next dose at the usual time.

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.

What if I take too much?

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 if you have taken some extra tablets and notice any signs of bleeding.

How to cope with side effects of ticagrelor

What to do about:

Pregnancy and breastfeeding

Ticagrelor and pregnancy

Ticagrelor is not recommended during pregnancy or if you're trying to get pregnant.

It's important to use contraception while you're taking ticagrelor to avoid becoming pregnant.

Talk to your doctor if you take ticagrelor and are trying to get pregnant. They may be able to recommend a more suitable medicine for you.

Ticagrelor and breastfeeding

Only take ticagrelor while breastfeeding if your doctor advises you to.

It's not known how much ticagrelor gets into breast milk, but it's likely to be a small amount, and your baby will not absorb a lot into their body from the breast milk.

If your doctor says it's OK for you to keep taking ticagrelor, then monitor your baby for any possible side effects, such as bruises or bleeding more easily than usual. However, it is unlikely that ticagrelor will cause any side effects in your baby.

Talk to your doctor, pharmacist, midwife or health visitor if you have any concerns about your baby while you're breastfeeding.

Cautions with other medicines

Some medicines affect the way ticagrelor works.

Tell your doctor if you're taking any of these medicines before you start taking ticagrelor:

Taking ticagrelor with everyday painkillers

Your doctor may prescribe low-dose aspirin (75mg tablets) to take together with ticagrelor.

Do not take aspirin for pain relief (300mg tablets) or ibuprofen while you're taking ticagrelor, unless a doctor has said it's OK. They increase the chance of bleeding.

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.
