Dose calculator
Example values — replace them with your semaglutide label. For total mg + mL, enter all medication and actual liquid in the vial, not the container’s capacity. If your label lists mg/mL, choose concentration.
Your conversion
5 mg ÷ 2 mL = 2.5 mg/mL. 1.7 mg ÷ 2.5 mg/mL × 100 = 68 units
Educational only. Always follow your prescriber's dose and confirm the numbers with your pharmacist.
1.7 mg in units, by vial strength
| Vial concentration | Units (U-100) | Volume |
|---|---|---|
| 2.5 mg/mL | 68 units | 0.68 mL |
| 5 mg/mL | 34 units | 0.34 mL |
Where 1.7 mg fits in the schedule
The fourth step on the Wegovy schedule (typically weeks 13–16) before the 2.4 mg maintenance dose. Your prescriber sets your actual schedule — follow their instructions.
The formula
units = (dose mg ÷ concentration mg/mL) × 100
Example at 2.5 mg/mL: 1.7 ÷ 2.5 × 100 = 68 units.
Check the label before converting
These calculations use example concentrations, not a universal semaglutide strength. If a label gives total medication and liquid volume, divide mg by mL first. For example, 5 mg in 2 mL gives 2.5 mg/mL. Use the semaglutide calculator for the numbers on your own label.
Compounded medications are not FDA-approved. The FDA’s semaglutide dosing-error alert explains how differing concentrations and confusion between units, mL, and mg can cause errors.
