For the prescription, Amoxil 250 mg #30 I tid rfx2, how many days should the prescription last?

To determine how long the prescription for Amoxil (amoxicillin) 250 mg with a quantity of 30 tablets and a dosing regimen of 'tid' (which stands for "three times a day") for a duration of 'rfx2' (which typically indicates that the patient should refill it twice), we can break down the information provided.

The total quantity of tablets prescribed is 30, and the patient is instructed to take the medication three times a day. To find out how many days the prescription will last, we can perform a simple calculation using the total number of tablets and the daily dosage.

The daily dosage, when taken tid, is 3 tablets per day (since the patient takes 1 tablet three times a day). By dividing the total amount of medication available (30 tablets) by the number of tablets taken per day (3), we can determine the total number of days the prescription will last:

30 tablets ÷ 3 tablets/day = 10 days.

Thus, the prescription will last for 10 days, making this the correct answer. This understanding enables proper medication management and scheduling for the patient as well as appropriate refill planning.
