Leuphasyl: 200 mg vial with 1 mL water
Quick answer
Adding 1 mL of bacteriostatic water to a 200 mg Leuphasyl vial gives 200 mg/mL (200000 mcg/mL), so each unit on a U-100 insulin syringe holds 2000 mcg. A 2 mg dose is 1 units (0.01 mL), and the vial holds about 100 doses of that size.
Concentration
- Vial: 200 mg Leuphasyl
- Bacteriostatic water: 1 mL
- Concentration: 200 mg/mL (200000 mcg/mL)
- 1 unit on a U-100 syringe = 2000 mcg
Leuphasyl dose to syringe units
| Dose | Syringe units (U-100) | Volume | Doses per vial |
|---|---|---|---|
| 3 mcg (protocol dose) | 0 units, too small to measure reliably | 0 mL | 66666 |
| 5 mcg (protocol dose) | 0 units, too small to measure reliably | 0 mL | 40000 |
| 2 mg | 1 units | 0.01 mL | 100 |
| 2.5 mg | 1.3 units | 0.013 mL | 80 |
| 5 mg | 2.5 units | 0.025 mL | 40 |
| 7.5 mg | 3.8 units | 0.038 mL | 26 |
| 10 mg | 5 units | 0.05 mL | 20 |
| 15 mg | 7.5 units | 0.075 mL | 13 |

Common questions
How many units is 2 mg of Leuphasyl from a 200 mg vial with 1 mL water?
2 mg is 1 units (0.01 mL) on a U-100 insulin syringe. With 1 mL of water in a 200 mg vial, each unit holds 2000 mcg. For comparison: 2.5 mg = 1.3 units, 5 mg = 2.5 units, 7.5 mg = 3.8 units.
What is the concentration of a 200 mg Leuphasyl vial mixed with 1 mL of water?
200 mg divided by 1 mL is 200 mg/mL, or 200000 mcg per mL. On a U-100 syringe (100 units = 1 mL) that is 2000 mcg per unit.
How many 2 mg doses are in a 200 mg vial?
About 100. The water volume changes how many units each dose takes, not how many doses the vial holds.
