Oxytocin: what the research shows
The “bonding hormone”, and one of the most used medicines in childbirth.
Also known as Pitocin, Syntocinon
At a glance
Approved worldwide to start or strengthen labor and to reduce bleeding after birth.
What is Oxytocin?
Oxytocin is a hormone of nine amino acids, made in the brain and released by the pituitary gland.
How does Oxytocin work?
It makes the womb contract during labor and helps milk flow during breastfeeding. It also plays a part in social bonding.
What does the research show?
- Given through a drip, synthetic oxytocin is a standard way to start or speed up labor and to prevent heavy bleeding after delivery (2024 review).
Known risks and side effects
- Too much can make contractions too strong, which can harm mother or baby, so it is only given under close medical supervision.
Is Oxytocin approved?
A medicines regulator, such as the FDA in the US or the EMA in Europe, has approved it for specific uses.
Approved worldwide to start or strengthen labor and to reduce bleeding after birth.
