Oxytocin 10 mg vial: how to reconstitute it
What a 10 mg vial of Oxytocin becomes once it is mixed, and what each dose reported in the sources draws to on a syringe. Every figure is arithmetic on the vial size in the heading — none of it is a recommendation, and the doses are the ones our sources describe rather than ones we picked.
Leading with
10 mg + 1 mL bacteriostatic water = 10 mg/mL
Chosen because it puts the reported doses on readable marks of a 1 mL U-100 syringe. Other volumes are perfectly valid — the dilution table further down covers them, and the concentration changes what every dose draws to.
What each reported dose draws to
At 10 mg/mL, on a 1 mL U-100 syringe. Every row names the source it came from, and a trial protocol and a community convention are not the same kind of information.
| Goal | Dose | Units | Doses in this vial | Source |
|---|---|---|---|---|
| Doses used in the intranasal research literatureA single administration in most study protocols · Nasal | 40 mcg – 80 mcg | 0.4 units – 0.8 units | 250 | Clinical trial |
| Obstetric useContinuous intravenous infusion, titrated to contractions · Intravenous | 1 mcg – 20 mcg | 0.01 units – 0.2 units | 10000 | Published review |
Check every figure against the vial in front of you before drawing. Vials are filled with an overage and labels are not a guarantee. Change any of these numbers in the calculator.
If you add a different amount of water
The same 10 mg of compound, at four common volumes. More water means a larger, easier-to-measure draw of a weaker solution; less water means the opposite. The amount of compound you inject is identical in every row — only the volume carrying it changes.

| 2 mL | 5 mg/mL | 0.8 units units · 0.008 mL |

Storage
Before mixing
Refrigerated at 2–8 °C.
After mixing
Refrigerated at 2–8 °C. Nasal solutions are handled more than injectables and contaminate more easily.
Other vial sizes
The same compound, different arithmetic.
Arithmetic on the vial size named above and the doses our sources report. Nothing here is a recommendation, a protocol or medical advice, and no clinician has reviewed it. Speak to a licensed healthcare provider before acting on any of it.
