Pletal belongs to a group of medicines called phosphodiesterase type 3 inhibitors.

It has several actions which include widening of some blood vessels and reducing the clotting activity (clumping) of some blood cells called platelets inside your vessels.

You have been prescribed Pletal for "intermittent claudication". Intermittent claudication is the cramp-like pain in your legs when you walk and is caused by insufficient blood supply in your legs. Pletal can increase the distance you can walk without pain since it improves the blood circulation in your legs. Cilostazol is only recommended for patients whose symptoms have not improved sufficiently after making life-style modifications (such as stopping smoking and increasing exercise) and after other appropriate interventions. It is important that you continue the modifications you have made to your life-style whilst taking cilostazol.


Do not take Pletal

  • if you are allergic (hypersensitive) to cilostazol or any of the other ingredients of Pletal.
  • if you have the condition "heart failure".
  • if you have persistent chest pain at rest, or have had a “heart attack” or any heart surgery in the last six months
  • if you have now or previously suffered from blackouts due to heart disease, or any severe disturbances of the heart beat.
  • if you know that you have a condition which increases your risk of bleeding or bruising, such as:
    • active stomach ulcer(s).
    • stroke in the past six months.
    • problems with your eyes if you have diabetes.
    • if your blood pressure is not well controlled.
  • if you are taking both acetylsalicylic acid and clopidogrel, or any combination of two or more medicines which can increase your risk of bleeding [ask your doctor or pharmacist if you are not sure]if you have severe kidney disease or moderate or severe liver disease.
  • if you are pregnant

Take special care with Pletal

Before taking Pletal make sure your doctor knows:

  • if you have a severe heart problem or any problems with your heart beat.
  • if you have problems with your blood pressure.

During treatment with Pletal make sure that

  • If you need to have surgery including having teeth removed, tell your doctor or dentist that you are taking Pletal.
  • If you experience easy bruising or bleeding, stop taking Pletal and tell your doctor.

Taking other medicines

Before you start taking Pletal please tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription.

You should specifically inform your doctor if you take some medicines usually used to treat painful and/or inflammatory conditions of muscle or joints, or if you take medicines to reduce blood clotting. These medicines include:

  • acetylsalicylic acid
  • clopidogrel
  • anticoagulant medicines (e.g. warfarin, dabigatran, rivaroxaban, apixaban or low molecular weight heparins).

If you are taking such medicines with Pletal your doctor may perform some routine blood tests.

Certain medicines may interfere with the effect of Pletal when taken together. They may either increase the side effects of Pletal or make Pletal less effective. Pletal may do the same to other medicines. Before you start taking Pletal, please tell your doctor if you are taking:

  • erythromycin, clarithromycin or rifampicin (antibiotics)
  • ketoconazole (to treat fungal infections)
  • omeprazole (to treat excess acid in the stomach)
  • diltiazem (to treat high blood pressure or chest pain)
  • cisapride (to treat stomach disorders)
  • lovastatin, simvastatin or atorvastatin (to treat high cholesterol in the blood)
  • halofantrine (to treat malaria)
  • pimozide (to treat mental illnesses)
  • ergot derivatives (to treat migraine, e.g. ergotamine, dihydroergotamine)
  • carbamazepine or phenytoin (to treat convulsions)
  • St. John’s wort (a herbal remedy)

If you are not sure if this applies to your medicines ask your doctor or pharmacist.

Before you start taking Pletal, please inform your doctor if you are taking medicines for high blood pressure because Pletal may have an additional lowering effect on your blood pressure. If your blood pressure falls too low, this could cause a fast heartbeat. These medicines include:

  • Diuretics (e.g., hydrochlorothiazide, furosemide)
  • calcium channel blockers (e.g., verapamil, amlodipine)
  • ACE inhibitors (e.g., captopril, lisinopril)
  • angiotensin II receptor blockers (e.g., valsartan, candesartan)
  • beta blockers (e.g., labetalol, carvedilol);

It may still be all right for you to take the above mentioned medicines and Pletal together and your doctor will be able to decide what is suitable for you.
