Like all medicines, clopidogrel can cause side effects, although not everyone gets them. Common side effects include indigestion, tummy pain, nausea (feeling sick) and diarrhoea (runny poos). These usually go away with time. Tell your doctor if troublesome.
Increased risk of bleeding
Clopidogrel increases your risk of bleeding. You might bleed or bruise more easily while you are taking clopidogrel. Minor bleeding such as a nosebleed should usually stop on its own. If you have a fall or hurt your head or body, get medical attention immediately, even if you feel okay.
