Mechanism of Action
Stimulates uterine smooth muscle contraction and mammary myoepithelial cell contraction promoting milk letdown. Acts via oxytocin receptors.
Side effects & warnings
Used for dystocia and milk letdown. DO NOT USE if obstructive dystocia (uterine rupture risk). Cervix must be dilated. Repeat doses with diminishing returns.
Each ExoticRx dose rule is graded by the strength of its primary evidence — see the editorial process.
