Effects on milk supply

Anticholinergics can inhibit lactation in animals, apparently by inhibiting growth hormone and oxytocin secretion.[ 1 - 5 ] Anticholinergic drugs can also reduce serum prolactin in nonnursing women.[ 6 ] 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.[ 7 ]
