Advice to take a minimal dose for a short time since anti-cholinergic drugs may decrease breast milk production. Check-up for anti-cholinergic symptoms (mouth dryness, constipation...)

Answer by DrLact: About YM 905 usage in lactation

Because there is no published experience with YM 905 during breastfeeding and it has a long half-life averaging 55 hours, an alternate drug may be preferred, especially while nursing a newborn or preterm infant. Long-term use of YM 905 might reduce milk production or milk letdown. During long-term use, observe the infant for signs of decreased milk production (e.g., insatiety, poor weight gain) and for anticholinergic symptoms (e.g., constipation, urinary retention, UTI, dry mouth).

YM 905 Possible Effects in Breastfeeding

Relevant published information in nursing mothers was not found as of the revision date. Anticholinergics can inhibit lactation in animals apparently by inhibiting growth hormone and oxytocin secretion.[1][2][3][4][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.
