To investigate the efficacy of a galactagogue, containing Sylimarin-phosphatidylserine (SILITIDIL) and galega consumed in the first month after delivery by mothers of preterm infants, in maintaining milk production during the first 3-6 months after delivery.Mothers of infants born at gestational age (GA) between 27 and 32 weeks, enrolled in our previous prospective, double-blind, randomized trial and randomly allocated to receive either the galactagogue (GG) or a placebo (PG), were asked about their milk production at 3 and 6 months after delivery.Of the 100 mothers involved in this study, 45 of GG and 44 of PG responded comprehensively to the questions asked. At the third month after delivery, exclusive human milk administration was reported by 22 mothers of GG and 12 mothers of PG (p 0.05), whereas 29 mothers of GG and 18 mothers of PG were able to administer50% of the amount of milk assumed. At the sixth month of life, only eight infants received exclusive human milk (six and two of GG and PG, respectively), and the data are not sufficient for a meaningful clinical evaluation.It is assumed that a galactagogue during the first month after delivery improves human milk administration to preterm neonates after discharge and for the first 3 months of life.
