[Lactation inhibition by the early postpartum administration of Methylergobrevin]

Lactation was found to be significantly inhibited by greater than or equal to 2.0 mg methylergometrin-bimaleinate administered during the early postpartal period, particularly when the treatment was started as early as on the first or second day of puerperium. Therefore, such ergometrin treatment should be avoided as far as possible in order to improve breast-feeding, which was shown to be of great importance for the mental, psychic and physical development of the newborn.
