How many units on a U-40 insulin syringe is a 8 mg dose at 6.67 mg/mL?

Asked 13 Feb 2025Modified 18 months agoViewed 25k times

Concretely: a U-40 insulin syringe · 8 mg · 6.67 mg/mL.

Please show the division. I want to check my own against yours.

I would like the general form as well as the specific number, so I can apply it again.

Is my approach right even if my number is wrong?

The arithmetic itself: milligrams to millilitres to insulin units, concentration after reconstitution, dose per draw, and vial-days per vial. Show…
