What this medicine is used for

BTC Clopidogrel contains the active ingredient clopidogrel (as besilate).

Clopidogrel belongs to a group of medicines known as antiplatelet medicines.

Antiplatelet medicines prevent the clumping of very small blood cells (platelets) to reduce the chances of blood clots forming.

Clopidogrel is used to prevent blood clots forming in hardened blood vessels as they can lead to events such as stroke, heart attack or death.

You may have been prescribed clopidogrel 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)
  • 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

Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed this medicine for another reason.

There is no evidence that this medicine is addictive.

This medicine is available only with a doctor’s prescription.

This medicine should not be used in children.

Some of the symptoms of an allergic reaction may include:

Before you start to take it

Tell your doctor if you have allergies to any other medicines, foods, preservatives or dyes.

  • any illness or disability that was caused by bleeding e.g. impaired sight or vision because of bleeding within the eye
  • recent serious injury
  • recent surgery (including dental surgery)
  • liver or kidney problems
  • a genetic condition which means that a certain enzyme (CYP2C19) in your liver works differently and can negatively affect the amount of clopidogrel converting into its active form, resulting in reduced effects (your doctor may perform a test for this condition and depending on results may change your dose or consider an alternative treatment option)
  • galactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption
  • allergies to other antiplatelet medicines (such as allergic to other antiplatelet medicines (such as ticlopidine, prasugrel)
  • rare hereditary problems of galactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption

Tell your doctor if you are planning to have an operation (including dental surgery). Your doctor will decide whether you need to stop clopidogrel prior to surgery.

If you have not told your doctor about any of the above, tell them before you start taking this medicine.

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

Taking other medicines

Tell your doctor or pharmacist if you are taking any other medicines, including any that you get without a prescription from your pharmacy, supermarket or health food shop.

  • non-steroidal anti-inflammatory drugs (NSAIDs), used to treat arthritis, period pain, inflammation, aches and pain
  • medicines used to treat stomach ulcers, reflux disease (also called heartburn) or prevent gastric reflux e.g. proton-pump inhibitors (such as omeprazole or esomeprazole) or cimetidine
  • some medicines used to treat infections e.g. ciprofloxacin, chloramphenicol, fluconazole, rifampicin, and voriconazole
  • medicines used to treat epilepsy e.g. phenytoin, carbamazepine and oxcarbazepine
  • some antidepressants e.g. fluoxetine, fluvoxamine and moclobemide
  • some medicines used to treat diabetes e.g. tolbutamide and repaglinide
  • tamoxifen or paclitaxel, used to treat breast cancer
