This medication is a first-line treatment for preventing and treating uterine atony because it stimulates uterine contractions effectively, helping to compress the uterine blood vessels and reduce the risk of excessive postpartum hemorrhage.

For a woman with a history of asthma, Oxytocin is particularly appropriate since it does not have the contraindications associated with some other medications used for uterine atony. Hemabate and Methergine, while they can also promote uterine contractions, may not be ideal in this scenario. Hemabate (Carboprost) can cause bronchoconstriction, which could exacerbate asthma symptoms, making it a less safe choice for women with a history of respiratory issues.
