Hyoscyamine Breastfeeding Warnings

There are no data on the excretion of hyoscyamine into human milk. Some experts recommend cautious use of hyoscyamine during breast-feeding due to the sensitivity of the neonate to anticholinergic agents (probably because of immaturity of motor endplates). Hyoscyamine is considered compatible with breast-feeding by the American Academy of Pediatrics.
