IMPORTANT WARNING:

Cilostazol should not be used by patients with congestive heart failure. If you have a history of heart disease, talk to your doctor about the potential risks associated with cilostazol before taking it.

Why is this medication prescribed?

Cilostazol is used to reduce the symptoms of intermittent claudication (pain in the legs that happens when walking and goes away with rest). Cilostazol helps people walk a longer distance before leg pain starts.

This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.

How should this medicine be used?

Cilostazol comes as a tablet to take by mouth. It is usually taken two times a day. It should be taken at least 30 minutes before or 2 hours after breakfast and dinner. Follow the directions on the prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take cilostazol exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Cilostazol controls the symptoms of intermittent claudication but does not cure it. It may take up to 12 weeks before you notice a benefit (increased walking distance) from cilostazol. Continue taking cilostazol even if you feel well. Do not stop taking cilostazol without talking to your doctor.

What should I do if I forget a dose?
