You have been given cilostazol to increase the distance you can walk.
Take one tablet in the morning and one tablet in the evening.
Take your doses 30 minutes before a meal (or alternatively, wait until two hours afterwards).
|Type of medicine||Vasodilator (widens blood vessels)|
|Used for||Intermittent claudication|
Cilostazol is used to treat intermittent claudication. This is a cramping pain that develops in the lower leg when you walk and is due to poor circulation. Vasodilators like cilostazol increase the distance you can walk before the pain develops.
Cilostazol works in two ways. It increases blood flow by widening the blood vessels of the affected areas and it also reduces the clotting activity of blood cells called platelets. Cilostazol is prescribed by specialist doctors when it is not possible to improve the symptoms of intermittent claudication by other means.
Before taking cilostazol
Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start taking cilostazol it is important that your doctor knows:
- If you have a heart condition or high blood pressure.
- If you have high blood sugar levels (diabetes mellitus).
- If you know you are at risk of bleeding - for example, if you have a stomach ulcer or if you have had surgery recently.
- If you have any problems with the way your liver works or the way your kidneys work.
- If you are pregnant or breast-feeding.
- If you are taking any other medicines. This includes any medicines you are taking which are available to buy without a prescription, as well as herbal and complementary medicines.
- If you have ever had an allergic reaction to a medicine.
How to take cilostazol
- Before you start this treatment, read the manufacturer's printed information leaflet from inside your pack. It will give you more information about cilostazol and will provide you with a full list of side-effects which you may experience from taking it.
- Take the tablets exactly as your doctor tells you to. It is usual to take one tablet twice a day, in the morning and evening. The usual strength of tablet is 100 mg, although a lower strength of tablet may be appropriate at times if you are also taking certain other medicines. Your doctor will tell you which is the right strength for you, and this will also be printed on the label of the pack of tablets to remind you.
- Swallow the tablets with a drink of water. Ideally, you should take the tablets 30 minutes before meals. If this is not possible, wait until two hours afterwards.
- If you forget to take a dose, don't worry, just remember to take your next dose when it is due. Do not take two doses together to make up for a forgotten dose.
Getting the most from your treatment
- Try to keep your regular appointments with your doctor. This is so your doctor can check on your progress and assess how cilostazol is working for you.
- If you are a smoker, you should try to stop. Smoking can narrow your blood vessels further and will make your condition worse. Your doctor or pharmacist can advise you about how to quit smoking.
- Keep your home warm. The cold cuts down the blood supply to your skin even before you feel cold. If you 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 will advise you on what type of exercise is suitable for you.
- Try to 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, see your doctor.
