Solifenacin Levels and Effects while Breastfeeding
Summary of Use during Lactation
Because there is no published experience with solifenacin 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 solifenacin 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).

Effects on Lactation and Breastmilk
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. 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.
