Vesicare Breastfeeding Warnings
A decision should be made to discontinue breastfeeding or discontinue the drug, taking into account the importance of the drug to the mother.
Excreted into human milk: Unknown
Excreted into animal milk: Yes
Comment:
-The effects in the nursing infant are unknown.
Because there is no published experience with this drug 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 might reduce milk production or milk letdown; therefore, during long-term use, the infant should be observed for signs of decreased milk production (e.g., insatiety, poor weight gain) and for anticholinergic symptoms (e.g., constipation, urinary retention, UTI, dry mouth).
