Question 1

How many units is a 250 mcg dose of Cagrilintide (5mg vial, 3ml diluent)?

Accepted Answer

15 units on a standard U-100 insulin syringe (0.15 ml). Mixing a 5mg vial of Cagrilintide with 3ml of bacteriostatic water gives a concentration of 1.67 mg/ml. On a U-100 insulin syringe that means: 250 mcg = 15 units · 500 mcg = 30 units · 1 mg = 60 units · 2 mg = 120 units · 4 mg = 240 units.

Question 2

What is the concentration of 5mg of Cagrilintide in 3ml?

Accepted Answer

5mg ÷ 3ml = 1.67 mg/ml.

Question 3

Which syringe do these unit marks refer to?

Accepted Answer

A standard U-100 insulin syringe, where 100 units = 1 ml. On U-50 or U-30 syringes the same volume reads as half or 30% of the U-100 marks. These are mathematical conversions for organizational purposes only — not medical advice.

Dose	Draw volume	U-100 units
250 mcg	0.15 ml	15 U
500 mcg	0.3 ml	30 U
1 mg	0.6 ml	60 U
2 mg	1.2 ml	120 U
4 mg	2.4 ml	240 U
