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.

When you must not take it

You should not take Clopidogrel Winthrop if:

  • you have a medical condition that is causing bleeding such as a stomach ulcer or bleeding within your head.
  • you suffer from severe liver disease.
  • you are breast feeding or intend to breast feed. Clopidogrel Winthrop passes into breast milk and, therefore, there is the possibility that the breast fed baby may be affected.
  • the packaging shows signs of tampering.
  • the expiry date on the pack has passed. If you use this product after the expiry date has passed, it may not work.

Do not take Clopidogrel Winthrop to treat any other complaint unless your doctor says it is safe. Do not give this medicine to anyone else.

Before you start to take Clopidogrel Winthrop

You must tell your doctor if:

  • You are pregnant or intend to become pregnant. Your doctor will discuss the possible risks and benefits of taking Clopidogrel Winthrop during pregnancy.
  • You are planning to have an operation (including dental surgery) in the next two weeks. Your doctor will decide whether or not you need to stop Clopidogrel Winthrop prior to surgery.
  • If you have or have had any medical conditions, especially the following:
    – bleeding disorders or blood clotting problems
    – liver or kidney problems
    – any illness or disability that was caused by bleeding, for example impaired sight or vision because of bleeding within the eye
    – recent serious injury
    – recent surgery (including dental surgery)
    – allergic to other antiplatelet medicines (such as ticlopidine, prasugrel)
    – rare hereditary problems of galactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption

If you have not told your doctor about any of the above, tell him/her before you start taking Clopidogrel Winthrop.

Some patients may not convert Clopidogrel Winthrop to its active form as well as other patients. These patients may not get the same benefit from Clopidogrel Winthrop. Your doctor may advise you to go for tests to determine if Clopidogrel Winthrop will adequately work for you. Based on the test results, your doctor may change your dose of Clopidogrel Winthrop or consider alternative treatments for you.
