What it is
Oxytocin is a 9-amino-acid peptide produced in the hypothalamus and released by the posterior pituitary. It acts through oxytocin receptors in the uterus, breast, brain, and other tissues. Synthetic oxytocin is one of the most widely used drugs in obstetrics.
What the evidence shows
For labor induction and postpartum hemorrhage, oxytocin has extensive human evidence and is standard of care. Intranasal oxytocin has been studied for autism spectrum disorder, social anxiety, depression, and trust/empathy, but meta-analyses show inconsistent effects and limited clinical utility outside research settings.
Risks & unknowns
When used obstetrically, oxytocin can cause uterine tachysystole, water intoxication, hypotension, and fetal distress. Intranasal use can cause headache, nausea, and nasal irritation. Misuse outside medical supervision is dangerous, especially in pregnancy.
Legal / regulatory status
Oxytocin is FDA-approved for labor induction and control of postpartum hemorrhage. Intranasal oxytocin for social or psychiatric indications is investigational. In sport it is not typically prohibited but is a prescription medication.
