Antimuscarinic agent with atropine-like action.

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

A high plasma protein-binding capacity makes it unlikely its passage into breast milk.
Its low oral bioavailability hinders the passage from ingested milk towards the infant’s plasma, except in preterm babies and immediate neonatal period, which may show an increased intestinal permeability. There are few poor metabolizers (CYP2D6 deficient) who may exhibit increasing oral bioavailability to 66%

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.
