Dose calculator
Example values — replace them with your tirzepatide 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
10 mg ÷ 2 mL = 5 mg/mL. 12.5 mg ÷ 5 mg/mL × 100 = 250 units
Educational only. Always follow your prescriber's dose and confirm the numbers with your pharmacist.
12.5 mg in units, by vial strength
| Vial concentration | Units (U-100) | Volume |

Where 12.5 mg fits in the schedule
A step between 10 mg and the 15 mg maximum. Your prescriber sets your actual schedule — follow their instructions.
The formula
units = (dose mg ÷ concentration mg/mL) × 100
Example at 5 mg/mL: 12.5 ÷ 5 × 100 = 250 units.
Check the label before converting
These calculations use example concentrations, not a universal tirzepatide strength. If a label gives total medication and liquid volume, divide mg by mL first. For example, 10 mg in 2 mL gives 5 mg/mL. Use the tirzepatide 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.
