Pyridoxine Breastfeeding Warnings

Pyridoxine is excreted into human milk. Neonatal seizures have been reported in infants whose mothers' breast milk contained 67 mcg/day. These seizures responded to pyridoxine therapy. Pyridoxine is considered compatible with breast-feeding by the American Academy of Pediatrics.

Pyridoxine has been reported to inhibit lactation at large doses. The recommend dietary allowance (RDA) of pyridoxine (vitamin B6) for lactating women is 2 mg/day, regardless of age, to ensure a vitamin B6 concentration of milk of 130 ng/mL.
