Oxytocin: 10 mg vial with 2 mL water
Quick answer
Adding 2 mL of bacteriostatic water to a 10 mg Oxytocin vial gives 5 mg/mL (5000 mcg/mL), so each unit on a U-100 insulin syringe holds 50 mcg. A 100 mcg dose is 2 units (0.02 mL), and the vial holds about 100 doses of that size.
Concentration
- Vial: 10 mg Oxytocin
- Bacteriostatic water: 2 mL
- Concentration: 5 mg/mL (5000 mcg/mL)
- 1 unit on a U-100 syringe = 50 mcg
Oxytocin dose to syringe units
| Dose | Syringe units (U-100) | Volume | Doses per vial |
|---|---|---|---|
| 50 mcg | 1 units | 0.01 mL | 200 |
| 100 mcg (protocol dose) | 2 units | 0.02 mL | 100 |
| 200 mcg (protocol dose) | 4 units | 0.04 mL | 50 |
| 250 mcg | 5 units | 0.05 mL | 40 |
| 300 mcg (protocol dose) | 6 units | 0.06 mL | 33 |
| 400 mcg (protocol dose) | 8 units | 0.08 mL | 25 |
| 500 mcg | 10 units | 0.1 mL | 20 |
| 750 mcg | 15 units | 0.15 mL | 13 |

Common questions
How many units is 100 mcg of Oxytocin from a 10 mg vial with 2 mL water?
100 mcg is 2 units (0.02 mL) on a U-100 insulin syringe. With 2 mL of water in a 10 mg vial, each unit holds 50 mcg. For comparison: 200 mcg = 4 units, 300 mcg = 6 units, 400 mcg = 8 units.
What is the concentration of a 10 mg Oxytocin vial mixed with 2 mL of water?
10 mg divided by 2 mL is 5 mg/mL, or 5000 mcg per mL. On a U-100 syringe (100 units = 1 mL) that is 50 mcg per unit.
How many 100 mcg doses are in a 10 mg vial?
About 100. The water volume changes how many units each dose takes, not how many doses the vial holds.
How much water should I add to a 10 mg Oxytocin vial?
The Crestigen Oxytocin protocol uses 3 mL. 2 mL works too as long as you calculate units for this concentration (5 mg/mL) and label the vial.
