What is Clopidogrel Winthrop used for
Clopidogrel Winthrop contains the medicine clopidogrel. Clopidogrel Winthrop belongs
to a group of medicines called anti-platelet medicines.
Platelets are very small blood cells which clump together during blood clotting.
By preventing this clumping, anti-platelet medicines reduce the chances of blood clots
forming (a process called thrombosis).
Clopidogrel Winthrop is used to prevent blood clots forming in hardened blood vessels
(a process known as atherothrombosis) which can lead to events such as stroke, heart
attack or death.
You may have been prescribed Clopidogrel Winthrop to help prevent blood clots forming
and to reduce the risk of stroke, heart attack and death because:
You have previously suffered a heart attack, stroke or have a condition known as peripheral
arterial disease (leg pain on walking or at rest).
You have suffered Acute Coronary Syndrome (either a severe type of chest pain called
unstable angina, or a heart attack). In this case you may also be prescribed aspirin.
Your doctor may have prescribed this medicine for another use. If you want more information,
ask your doctor.
Clopidogrel Winthrop is only available on a doctor's prescription.
