How many units / semaglutide
How Many Units Is 2.4 mg of Semaglutide?
Divide 2.4 mg by the known strength (mg per mL) to get mL, then multiply by 100 for units on a U-100 insulin syringe. At 1 mg/mL, the math gives 240 units. At 2.5 mg/mL it’s 96 units, and at 5 mg/mL it’s 48 units. These numbers aren’t a recommendation. They also don’t mean an approved product should be drawn up with an insulin syringe. Wegovy comes in 2.4 mg/0.75 mL pens and syringes, and the FlexTouch pen gives four 2.4 mg/0.75 mL doses. Follow the instructions that come with the brand-name device. If you’re measuring from a vial and the dose fits, a smaller syringe spreads each unit over more of its length. The FDA has said that syringes much bigger than the dose have played a part in dosing mistakes with compounded medicines.

| 1 mg/mL | 2.4 mL | 240 | more than a 1 mL syringe holds |
| 2.5 mg/mL | 0.96 mL | 96 | right on a line |

This is a lot of liquid for one dose. It may be worth checking the vial strength with your pharmacist.
| Dose | Units | mL | Syringe |
|---|---|---|---|
| 0.25 mg | 10 units | 0.10 mL | 1.0 mL syringe |
| 0.5 mg | 20 units | 0.20 mL | 1.0 mL syringe |
| 1 mg | 40 units | 0.40 mL | 1.0 mL syringe |
| 1.7 mg | 68 units | 0.68 mL | 1.0 mL syringe |
| 2 mg | 80 units | 0.80 mL | 1.0 mL syringe |
| 2.4 mg | 96 units | 0.96 mL | 1.0 mL syringe |
These doses come from the FDA labels. Your prescriber decides which dose you take and when.
This is math only, not medical advice. Follow your prescriber's and pharmacist's instructions.
