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.

Higher concentrations of cilostazol could increase the possibility of toxic effects. Therefore, a dose of 50 mg twice daily should be considered when drugs that may increase the concentration of cilostazol also are being used.

Combining pletal with other drugs that interfere with the blood clotting process may increase the likelihood of bleeding.

A high fat meal increases the absorption of cilostazol. Grapefruit juice could increase the concentration of cilostazol. Therefore, grapefruit juice should not be taken by patients on cilostazol.

PREGNANCY: The use of cilostazol in pregnancy has not been adequately studied.

NURSING MOTHERS: Cilostazol has not been adequately studied in women who are breastfeeding.
