Answer by Dr. Ru: About Phenoxymethylpenicillinum usage in lactation

Phenoxymethylpenicillinum is excreted into breast milk in non-significant amounts without side-effects observed among breastfed infants from treated mothers. Plasma levels in those infants were shown to be low or undetectable. Penicillin is a broad spectrum antibiotic that is commonly used in Pediatrics and Neonatology with very good tolerance even in premature newborns.

Answer by DrLact: About Phenoxymethylpenicillinum usage in lactation

Limited information indicates that Phenoxymethylpenicillinum produces low levels in milk that are not expected to cause adverse effects in breastfed infants. Occasionally disruption of the infant's gastrointestinal flora, resulting in diarrhea or thrush have been reported with penicillins, but these effects have not been adequately evaluated. Phenoxymethylpenicillinum is acceptable in nursing mothers.

Phenoxymethylpenicillinum Side Effects in Breastfeeding

In one study, 12 infants were breastfed during maternal Phenoxymethylpenicillinum therapy. Seven appeared normal, 3 had looser stools than normal, and 1 had a rash on the buttocks on the last day of therapy. These effects were possibly related to Phenoxymethylpenicillinum in milk, but no control group was present. One infant had stains of blood in the stool, but it had happened once prior to maternal Phenoxymethylpenicillinum treatment.[1]
