Cilostazol

About cilostazol

This belongs to the group of medicines known as Peripheral vasodilators.

Vasodilators work by widening the blood vessels.

Cilostazol is used to treat intermittent claudication. This is a cramping pain that develops in the legs when you walk and is due to bad circulation. cilostazol relieves these symptoms by increasing the blood flow to the affected areas and reducing how much the blood clots. It increases the distance you can walk before pain develops.

Cilostazol is available in tablet form

It is also sometimes known as: Pletal. You may notice the use of either of these names on the packaging of your medicine.

Before taking cilostazol

Before taking cilostazol make sure your doctor or pharmacist knows:

  • if you are pregnant, trying for a baby or breast-feeding
  • if you suffer from liver or kidney problems
  • if you suffer from uncontrolled hypertension (high blood pressure)
  • if you suffer from any kind of heart problem or peptic (stomach) ulcers
  • if you suffer from diabetes or retinopathy (damaged retina in the eye)
  • if you bruise or bleed easily
  • if you have had surgery in the past three months
  • if you have had blackouts or a stroke in the past
  • if you have ever had an allergic reaction to this or any other medicine
  • if you are taking any other medicines, including those available to buy without a prescription, herbal or complementary medicines

How to take cilostazol

  • Always read the manufacturer's information leaflet, if possible, before beginning treatment.
  • Take cilostazol exactly as directed by your doctor.
  • If you are taking cilostazol in divided doses, they should be taken in the morning and evening.
  • Cilostazol should be taken 30 minutes before, or two hours after, breakfast and evening meal.
  • Try to take this medicine at the same times each day to avoid missing any doses.
  • If you miss a dose of cilostazol take it as soon as you remember. However, if it is almost time for your next dose, skip the missed dose and continue taking it at the usual times. Never take two doses at the same time to make up.
  • This medicine is for you. Never give it to others even if their condition appears to be the same as yours.
  • Never take more than the prescribed dose. If you suspect that you or someone else has taken an overdose of cilostazol contact your doctor or go to the accident and emergency department of your local hospital at once. Always take the container with you, if possible, even if it is empty.

Getting the most from your treatment

  • Before taking any 'over-the-counter' medicine (especially aspirin containing medicines), check with your pharmacist which medicines are safe for you to take alongside cilostazol.
  • Cilostazol can cause dizziness. Make sure your reactions are normal before driving, operating machinery or doing any other jobs which could be dangerous if you were not fully alert.
  • It may take some time for cilostazol to work (up to 16-24 weeks of treatment). If you feel that the medicine is not working, do not stop taking it. Make an appointment to see your doctor.
  • Do not smoke. Smoking can narrow your blood vessels further and will make your condition worse.
  • Keep your home warm. The cold cuts down the blood supply to the skin even before you feel cold. If you do go out in the cold, wrap up well in warm clothing, especially gloves and socks.
  • Regular exercise will help to improve your circulation. Your doctor can advise you on how much exercise and the type of exercise suitable for you.
  • Take good care of your hands and feet. Examine your hands, legs and feet regularly for any signs of damage or infection. If you notice any changes consult your doctor.
