Few problems have been reported in infants whose mothers took it.
It can cause gastroenteritis by altering the intestinal flora of the infant. (Ilett 2006, Benyamini 2005, Ito 1993)
A case of allergic reaction to cephalexin through its own mother’s milk has been published on a previously sensitized infant after administration of another cephalosporin intravenously. (Chu 2019)
Cephalosporins are widely used in Pediatrics with very good tolerance, even from the neonatal period, so it is very unlikely that, in small amounts through their own mothers’milk, they can cause problems for the infant.
