For a prescription of Amoxil 250 mg #30 t.i.d. rfx2, how many days should the prescription last?

To determine how long a prescription of Amoxil 250 mg with the instructions of taking it three times daily (t.i.d.) for a quantity of 30 tablets will last, it is essential to break down the dosing and the total number of tablets.

The prescription indicates that the patient is to take 250 mg three times per day. This means that each day, the patient will consume a total of 750 mg of Amoxil (which is 250 mg taken three times). Given that there are 30 tablets prescribed, we can calculate how many days the supply will last by determining the daily dosage.

Since the patient takes 3 doses a day and there are 30 tablets, we can divide the total number of tablets (30) by the number of tablets taken per day (3).

30 tablets / 3 tablets per day = 10 days

Thus, the prescription should last for 10 days, which aligns with the provided answer option. The rationale behind this calculation is based on the simple division of total pills by the number of pills consumed daily, resulting in a clear understanding of the duration of the medication's supply.
