An antilactogenic effect of pyridoxine.

The efficacy of pyridoxine in suppression of lactation was studied. Patients under study included the cases of stillbirths, neonatal deaths and second trimester abortions. The clinical response was good in 80%, fair in 14% and poor in 6% of cases. Administration of pyridoxine only was associated with a rapid and trouble-free suppression of lactation in 94% of cases.
