Oxybutinyn Levels and Effects while Breastfeeding
Summary of Use during Lactation
No information is available on the use of oxybutynin during breastfeeding. Long-term use of oxybutynin might reduce milk production or milk letdown, but a single dose is not likely to interfere with breastfeeding. During long-term use, observe for signs of decreased lactation (e.g., insatiety, poor weight gain).

Effects on Lactation and Breastmilk
Anticholinergics can inhibit lactation in animals apparently by inhibiting growth hormone and oxytocin secretion. Anticholinergic drugs can also reduce serum prolactin in nonnursing women. The prolactin level in a mother with established lactation may not affect her ability to breastfeed. The manufacturer reports that cases of lactation suppression have been reported with some oxybutynin (immediate-release) formulations in postmarketing surveillance.
