Metformin 500 mg, sig: 1 tablet by mouth twice daily. Quantity dispensed: 60 tablets. What is the day supply?
a.15 days
b.30 days
c.45 days
d.60 days
Explanation
The patient takes 1 tablet x 2 times daily = 2 tablets per day. 60 tablets / 2 tablets per day = 30 days. The tempting error is answering 60 days by treating the dispensed quantity as if it were one tablet per day.
