Is Fesoterodine compatible with breastfeeding? Do we have alternatives for Fesoterodine?


September 19, 2016 (Low Risk)

Antimuscarinic agent with atropine-like action. It is metabolized in Tolterodine

At latest update no published data on excretion into breast milk were found.

Until more published data on this drug in relation to breastfeeding is available, a known safer alternative as Tolterodine should be preferred with more favorable pharmacokinetics characteristics for lactation (e.g. high protein-binding capacity, faster elimination and lower oral bioavailability), particularly during the neonatal period and prematurity case.

Take as smallest dose as possible and avoid long-term use since anticholinergics can reduce milk production.

Monitoring anticholinergic symptoms in infants (dry mouth, constipation ..) is warranted.
