How to mix a 40 mg vial
Find the column for the amount of water you added to the vial. The number is how far to draw on a U-100 insulin syringe, where 100 units is 1 mL. This is arithmetic on the label, not a recommended dose.
How to read an insulin syringe · How much water to add
| Dose | 1 mL water | 2 mL water | 3 mL water |
|---|---|---|---|
| 2.5 mg | 6.3 units 16 doses/vial | 12.5 units 16 doses/vial | 18.8 units 16 doses/vial |
| 15 mg | 37.5 units 2 doses/vial · 10.00 mg left over | 75.0 units 2 doses/vial · 10.00 mg left over | Over 100 units: will not fit one U-100 syringe |
