    • The prescription states TID, which means 3 tablet(s) per day.
    • Total duration of the treatment is 5 days.
    • Number of tablets administered during this period = 5 × 3 = 15;
    • Strength of one tablet = 250 mg.
    • Therefore, Total mg of antibiotic taken during this period = 15 × 250.
    250 mg = 15 × 250 mg
    400,000 unit x

    Therefore, x = 6,000,000
