Below are common setups. For any vial size, water volume, dose or syringe, use the interactive reconstitution calculator (with a live syringe).
| Vial | Water | Concentration | 250 mcg | 500 mcg |
|---|---|---|---|---|
| 5 mg | 1 mL | 5000 mcg/mL | 5 U | 10 U |
| 5 mg | 2 mL | 2500 mcg/mL | 10 U | 20 U |
| 5 mg | 3 mL | 1667 mcg/mL | 15 U | 30 U |
| 10 mg | 2 mL | 5000 mcg/mL | 5 U | 10 U |
| 10 mg | 3 mL | 3333 mcg/mL | 7.5 U | 15 U |
Units are on a U-100 insulin syringe (1 unit = 0.01 mL). More water = larger, easier-to-read draws.
