Mechanism of action

Posterior pituitary peptide hormone that stimulates uterine smooth muscle contraction and myoepithelial cell contraction in the mammary gland for milk let-down.

Side effects & warnings

Do not use in animals with dystocia due to fetal malpresentation until corrected. Overdose can cause uterine rupture. IV provides rapid onset (1 min) vs IM (3-5 min). Low dose for milk let-down; higher dose for uterine contraction.

Oxytocin (Livestock) dosing in other species

Why a species-specific page? Oxytocin (Livestock) pharmacokinetics differ across species: dose ranges, intervals, and route preferences are not interchangeable. Cross-extrapolation from canine doses is unsafe in swine — the rules above are the citations specific to this species, not generic recommendations.
