Leuphasyl: 200 mg vial with 3 mL water
Quick answer
Adding 3 mL of bacteriostatic water to a 200 mg Leuphasyl vial gives 66.67 mg/mL (66666.7 mcg/mL), so each unit on a U-100 insulin syringe holds 666.7 mcg. A 750 mcg dose is 1.1 units (0.011 mL), and the vial holds about 266 doses of that size.
Concentration
- Vial: 200 mg Leuphasyl
- Bacteriostatic water: 3 mL
- Concentration: 66.67 mg/mL (66666.7 mcg/mL)
- 1 unit on a U-100 syringe = 666.7 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 |
| 750 mcg | 1.1 units | 0.011 mL | 266 |
| 1 mg | 1.5 units | 0.015 mL | 200 |
| 1.5 mg | 2.2 units | 0.023 mL | 133 |
| 2 mg | 3 units | 0.03 mL | 100 |
| 2.5 mg | 3.7 units | 0.038 mL | 80 |
| 5 mg | 7.5 units | 0.075 mL | 40 |

Common questions
How many units is 750 mcg of Leuphasyl from a 200 mg vial with 3 mL water?
750 mcg is 1.1 units (0.011 mL) on a U-100 insulin syringe. With 3 mL of water in a 200 mg vial, each unit holds 666.7 mcg. For comparison: 1 mg = 1.5 units, 1.5 mg = 2.2 units, 2 mg = 3 units.
What is the concentration of a 200 mg Leuphasyl vial mixed with 3 mL of water?
200 mg divided by 3 mL is 66.67 mg/mL, or 66666.7 mcg per mL. On a U-100 syringe (100 units = 1 mL) that is 666.7 mcg per unit.
How many 750 mcg doses are in a 200 mg vial?
About 266. The water volume changes how many units each dose takes, not how many doses the vial holds.
