Concentrations stated on the labels, in syringe-unit terms
Arithmetic conversion of the label concentrations (1 U-100 unit = 0.01 mL). Shown for understanding the numbers only — the pens have their own dose counters.
| Label concentration | mg per 0.01 mL | mcg per 0.01 mL |
|---|---|---|
| 0.68 mg/mL (Ozempic 2 mg/3 mL) | 0.0068 | 6.8 |
| 1.34 mg/mL (Ozempic 4 mg/3 mL) | 0.0134 | 13.4 |
| 2.68 mg/mL (Ozempic 8 mg/3 mL) | 0.0268 | 26.8 |
| 3.2 mg/mL (Wegovy FlexTouch) | 0.0320 | 32.0 |
