How many days supply does metronidazole vaginal gel 70 g with directions of 5 g twice daily provide?

To determine how many days supply the metronidazole vaginal gel provides when using it at a dosage of 5 g twice daily, you can follow these steps:

1. Calculate the total daily dosage: Since the instructions are to use 5 g twice daily, you would multiply 5 g by 2. This results in a total of 10 g of gel used per day.

2. Determine the total amount available: The total available amount of metronidazole vaginal gel is 70 g.

3. Calculate the number of days the supply will last: To find out how many days the 70 g supply will last at a usage of 10 g per day, you divide the total amount by the daily amount. So, you would calculate 70 g divided by 10 g/day.

This gives you 7 days (70 g ÷ 10 g/day = 7 days).

Therefore, the correct answer indicates that the 70 g of metronidazole vaginal gel will provide a supply sufficient for 7 days of treatment, based on the prescribed dosing schedule.
