If amoxicillin is dispensed as 100 mg/mL and the prescription is for 1 tablespoon TID, how many days will 540 mL last?

To determine how many days the prescribed amoxicillin will last, we first need to calculate the total amount of medication taken in a single day. The prescription states to take 1 tablespoon three times a day (TID).

1 tablespoon is equivalent to approximately 15 mL. Therefore, if the patient takes 15 mL TID, the total daily dosage is calculated as follows:

• Daily dosage = 15 mL x 3 (times per day) = 45 mL per day.

Now, we have 540 mL of amoxicillin available. To find out how many days the supply will last, we divide the total volume of medication by the daily dosage:

• Number of days = Total volume / Daily dosage = 540 mL / 45 mL per day = 12 days.

Thus, the correct answer indicates that the medication will last for 12 days, making it the accurate choice based on the calculations involved in daily dosage and total medication available.
