What Piax is used for

PIAX contains the medicine clopidogrel. Clopidogrel belongs to a group of medicines known as antiplatelet medicines.
Platelets are very small blood cells which clump together during blood clotting. By preventing this clumping, antiplatelet medicines reduce the chances of blood clots forming (a process called thrombosis).
Piax 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 have been prescribed Piax 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.
Piax is only available on a doctor’s prescription.

Before you take Piax

When you must not take it

Do not take Piax if:
you are allergic to any medicine containing clopidogrel
you are allergic to any of the ingredients listed at the end of this leaflet
Some of the symptoms of an allergic reaction may include shortness of breath, wheezing or difficulty breathing, swelling of the face, lips, tongue or other parts of the body and rash, itching or hives on the skin
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
Piax passes into breast milk and, therefore, there is the possibility that the breast fed baby may be affected.
Piax is not recommended for children because the safety and effectiveness of Piax in children have not been established.
Do not take this medicine after the expiry date printed on the pack or if the packaging is torn or shows signs of tampering.
If it has expired or is damaged, return it to your pharmacist for disposal.
If you are not sure whether you should start taking this medicine, talk to your doctor.

Before you start to take it

Tell your doctor if you have allergies to any other medicines, foods, preservatives or dyes.
Tell your doctor if you have or have had any of the following medical conditions:
bleeding disorders or blood clotting 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)
liver or kidney problems
allergic to other antiplatelet medicines (such as ticlopidine, prasugrel).
Tell your doctor if you are pregnant or plan to become pregnant. Your doctor will discuss the possible risks and benefits of taking Piax during pregnancy.
Tell your doctor if 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 Piax prior to surgery.
If you have not told your doctor about any of the above, tell him/her before you start taking Piax.
Some patients may not convert Piax to its active form as well as other patients. These patients may not get the same benefit from Piax. Your doctor may advise you to go for tests to determine if Piax will adequately work for you. Based on the test results, your doctor may change your dose of Piax 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 buy without a prescription from your pharmacy, supermarket or health food store.
Some medicines and Piax may interfere with each other. These include:
medicines that “thin the blood”. The most common examples of these include aspirin, heparins and warfarin. There are other medicines used to ‘thin the blood’.
Check with your doctor or pharmacist to see if any medicine you take may have this effect.
non-steroidal anti-inflammatory drugs (NSAIDS) – medicines used to treat arthritis, period pain, aches and pains,
medicines used to treat stomach ulcers or reflux disease (also called heartburn),
Some medicines used to treat infections (e.g. ciprofloxacin, chloramphenicol, fluconazole and voriconazole),
Some antidepressant medicines
medicines used to treat epilepsy (e.g. carbamazepine, oxycarbazepine and phenytoin),
medicines used to treat diabetes (e.g. tolbutamide, repaglinide),
fluvastatin – a medicine used to lower cholesterol,
medicines used to treat breast cancer (e.g. tamoxifen, paclitaxel),
medicines used to prevent gastric reflux – proton pump inhibitors (e.g. omeprazole).
Certain type of pain relief medicines called opiates.
These medicines may be affected by Piax or affect how well Piax works.
Your doctor may need to change the amount of your medicines, or you may need to take different medicines.
If you are unsure about any medicine you are taking you should check with your doctor or pharmacist. They will have more information on medicines to be careful with or avoid while taking Piax.
