Is Phenoxymethylpenicillinic acid Safe in Breastfeeding

I am a breastfeeding mother and i want to know if it is safe to use Phenoxymethylpenicillinic acid? Is Phenoxymethylpenicillinic acid safe for nursing mother and child? Does Phenoxymethylpenicillinic acid extracts into breast milk? Does Phenoxymethylpenicillinic acid has any long term or short term side effects on infants? Can Phenoxymethylpenicillinic acid influence milk supply or can Phenoxymethylpenicillinic acid decrease milk supply in lactating mothers?

Phenoxymethylpenicillinic acid 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. Be aware of false negative results that may be obtained from infants with bacterial cultures when the mother is on antibiotics.

Limited information indicates that Phenoxymethylpenicillinic acid 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. Phenoxymethylpenicillinic acid is acceptable in nursing mothers.

In one study, 12 infants were breastfed during maternal Phenoxymethylpenicillinic acid 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 Phenoxymethylpenicillinic acid 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 Phenoxymethylpenicillinic acid treatment.[1]
