Hyoscyamine Pregnancy Warnings

Hyoscyamine has been assigned to pregnancy category C by the FDA. Animal studies have not been reported. There are no controlled data in human pregnancy. Hyoscyamine is only recommended for use during pregnancy when there are no alternatives and benefit outweighs risk.

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.
