For a dose of , draw to
units
That's of liquid.
- One vial gives you
- Syringe
How the math works
- Divide your dose by the strength. A 0.5 mg dose of 2.5 mg/mL semaglutide is 0.5 ÷ 2.5 = 0.2 mL.
- Multiply mL by 100 to get units. On a U-100 syringe, 1 mL = 100 units, so 0.2 mL = 20 units.
- Divide what's in the vial by your dose. A 2 mL vial at 2.5 mg/mL holds 5 mg, so it gives 10 doses of 0.5 mg.
Always follow your prescription
