Ozempic Calculations (Questions and Answers)

Question 1: A patient is prescribed Ozempic 0.5 mg once weekly. The pharmacy dispenses one 2 mg/3mL pen.

How many days will this pen last?

A. 7 days
B. 14 days
C. 28 days
D. 56 days

Answer: C. 28 days

Explanation:
The pen contains 2 mg total.
The patient takes 0.5 mg per week.
So, 2 mg ÷ 0.5 mg/week = 4 weeks of medication
4 weeks × 7 days = 28 days

For weekly medications, always convert “weeks” to days by multiplying by 7.

Question 2: Question 2: A patient is prescribed Ozempic 1 mg once weekly.

How many days will a 4 mg/3 mL pen last?

A. 14 days
B. 21 days
C. 30 days
D. 28 days

Answer: D. 28 days

Explanation:
The pen contains 4 mg total.
The patient uses 1 mg per week.
4 mg ÷ 1 mg/week = 4 weeks
4 weeks × 7 days = 28 days

Always look at total milligrams in the pen and divide by the weekly dose to get number of weeks, then multiply by 7 to get days.

Question 3: Question3: A patient is prescribed Ozempic with the directions, take 0.25 mg once weekly for 4 weeks, then increase to 0.5 mg once weekly thereafter. The pharmacy dispenses one pen (2 mg/3 mL).

How many days will this pen last?

A. 28 days
B. 42 days
C. 56 days
D. 70 days

Answer: B. 42 days

Explanation:
First, calculate how much Ozempic is used each week, then figure out how long the total 2 mg in the pen will last.

Step 1: Weeks 1–4 at 0.25 mg/week 0.25 mg × 4 weeks = 1 mg
Step 2: Remaining Ozempic in pen 2 mg – 1 mg = 1 mg left
Step 3: Weeks at 0.5 mg/week 1 mg ÷ 0.5 mg/week = 2 more weeks
So the total weeks of use = 4 (initial) + 2 (after titration) = 6 weeks Convert weeks to days: 6 weeks × 7 days = 42 days
