Cilostazol is often prescribed to patients who experience pain in their legs while walking due to problems with the blood vessels in the legs. This medication improves the blood flow to the legs so that patients can more easily walk. It can take up to 12 weeks for the medication to work.
People who take this medication are at increased risk for heart failure. Patients who have ever suffered from congestive heart failure should not take this medication because of this risk. The congestive heart failure caused by this drug can be fatal.
Patients should be careful of taking any anticoagulants, including over-the-counter drugs such as aspirin, while on Cilostazol, as these drugs can interact with one another and cause excessive bleeding.
