Oxytocin dosage in published studies and labels

These are the doses used for Oxytocin in FDA labelling and published clinical studies, reported as each source states them, one row per regimen. They describe what was studied or approved for a specific population. They are not a recommendation, and none of them is a dose for any individual.

Studied regimens and sources

Oxytocin has an FDA-approved human dosage only in obstetrics. The Pitocin label starts labor induction at 0.5–1 milliunits per minute by intravenous infusion, raised by 1–2 milliunits per minute every 30–60 minutes to the needed contraction pattern; after delivery it lists 10 units intramuscularly, or 10–40 units added to an intravenous infusion. Intranasal oxytocin has only been studied in trials, for example 16 IU a day in children with Prader-Willi syndrome.

Where sources disagree

  • Oxytocin is dosed in units, not milligrams, and the approved infusion is dosed per minute by uterine response. A milligram figure or a fixed daily dose does not describe the approved use.
  • The label states Pitocin is not indicated for elective induction of labor, and every approved use is in obstetrics. Intranasal oxytocin for social, appetite or mood outcomes has only been studied in trials.
