Cilostazol has not been studied in patients with leg pain at rest, leg ulcers due to reduced flow of blood, gangrene or rapidly progressing claudication.

Other important side effects which have also been reported with cilostazol include a reduction in numbers of white blood cells and platelets. Severe skin reactions also have been reported.

Cilostazol inhibits the enzyme phosphodiesterase III. Other drugs that inhibit this enzyme have caused death in individuals with heart failure. Therefore, individuals with heart failure should not use cilostazol.



PREPARATIONS: Tablets: 50 and 100 mg

STORAGE: Tablets should be stored below 25 C (77 F). Brief exposures to 30 C (86 F) are allowed.

DOSING: The dose is 100 mg twice daily. Cilostazol should be taken at least half an hour before or two hours after dinner and breakfast to prevent food from affecting its absorption.

DRUG INTERACTIONS: Erythromycin (E.E.S, Erythrocin), omeprazole (Prilosec) and diltiazem (Cardizem) increase the concentration of cilostazol by blocking the action of enzymes that destroy cilostazol. Though not specifically studied, a similar interaction could occur with ketoconazole (Nizoral), itraconazole (Sporanox), fluconazole (Diflucan), miconazole (Monistat), fluvoxamine (Luvox), fluoxetine (Prozac), nefazodone (Serzone) and sertraline (Zoloft). Diltiazem (Cardizem) and omeprazole (Prilosec) also increase concentrations of cilostazol.
