The only adverse event resulting in discontinuation of therapy in ≥ 3% of patients treated with PLETAL 50 or 100 mg twice daily was headache, which occurred with an incidence of 1.3%, 3.5%, and 0.3% in patients treated with PLETAL 50 mg twice daily, 100 mg twice daily, or placebo, respectively. Other frequent causes of discontinuation included palpitation and diarrhea, both 1.1% for cilostazol (all doses) versus 0.1% for placebo.
The most commonly reported adverse events, occurring in ≥ 2% of patients treated with PLETAL 50 or 100 mg twice daily, and with a frequency higher than placebo, are shown in the table (below).
