Clopidogrel may not be suitable to take if you have certain health conditions or are taking other medications.
When to avoid clopidogrel
Clopidogrel should not be taken if you have:
- an active (bleeding) peptic ulcer
- recently had a brain haemorrhage
- haemophilia or any other bleeding disorder
Clopidogrel must not be given to anyone under 16 years old, unless under specialist advice.
Read information about how clopidogrel interacts with other medications.
Using clopidogrel with caution
Clopidogrel should be taken with caution if you:
- have liver problems
- have kidney problems
- are at risk of bleeding, for example, if you are at risk of peptic ulcers
Tell your GP if you've had an allergic reaction to any medications before taking clopidogrel.
Some people are advised to stop taking clopidogrel seven days before a planned operation or dental extraction (removal of a tooth). This should always be on the advice of your doctor or surgeon.
Pregnancy and breastfeeding
Clopidogrel is not recommended if you're pregnant or breastfeeding. This is because there's very little information on its use in pregnant and breastfeeding women.
