Antibacterial carbapenem beta-lactam with indications similar to imipenem.Intravenous administration a daily dose. It is excreted in breast milk in a clinically insignificant amount (Merck 2012). Authorized pediatric use in infants from 3 months of age. Its low oral bioavailability would make it difficult for it to pass to the infant’s plasma ingesting breast milk, except in preterm infants and in the immediate neonatal period when there may be increased intestinal permeability. The possible negativity of cultures in febrile infants whose mothers take antibiotics should be taken into account, as well as the possibility of gastroenteritis due to altered intestinal flora (Benyamini 2005, Ito 1993, Kafetzis 1981).
