Notes for 10 mg/mL

At 10 mg/mL, 1 unit is 0.1 mg and 10 units is 1 mg.
Listed doses up to 2.4 mg fit a 0.5 mL (50-unit) syringe.
Listed doses up to 2.4 mg fit a 0.3 mL (30-unit) syringe.

Check the strength on every new vial

Units only mean something for one strength. If 20 units was 0.5 mg on a 2.5 mg/mL vial, the same 20 units from a 10 mg/mL vial is 2 mg, not 0.5 mg.

In July 2024 the FDA warned about dosing errors with compounded semaglutide, including mix-ups between mg, mL and units (FDA alert). The same math applies to any vial.
