Oxytocin is not contraindicated in twin gestations; studies show twins respond to oxytocin augmentation similarly to singletons, with comparable doses and outcomes [Fausett et al., 1997, PMID 9241293].  
Amniotomy often shortens labor and reduces the proportion of women who subsequently need oxytocin or lowers the required dose [Seitchik et al., 1985, PMID 4073154].  
Augmentation protocols have not been shown to raise operative (instrumental or cesarean) delivery rates in randomized trials and meta-analyses [Pergialiotis et al., 2022, PMID 33441039].  
Because oxytocin can provoke tachysystole/uterine hyper-stimulation, careful dosing is required [Simpson & James, 2008, PMID 18342288].
