- Oxytocin Injection
Oxytocin is a hormone secreted by the pituitary gland and stored in the brain. Oxytocin is released during labor, causing contractions of the uterus and milk letdown. It may also be used after foaling to help stabilize the mare's uterus and prevent complications.
Drugs containing oxytocin may be given to induce labor or to increase contractions during a difficult phase of labor. After foaling, it may be used to stimulate contractions to expel the placenta, control bleeding, and contract the uterus. Some veterinarians use it after breeding to evacuate any excess fluid from the mare's uterus.
