双氯西林

Very Low Risk

Safe. Compatible. Minimal risk for breastfeeding and infant.

Penicillin that is resistant to staphylococcal penicillinase.
Administered orally or intravenously every 6 hours.

Like most penicillins (Nau 1987) it is excreted through breast milk in clinically insignificant amounts (Muysson 2020, Matsuda 1984) therefore there is no published data or even the expectation that problems could arise on the breastfeeding infants of mothers because of taking this drug

Widely used in the treatment of mastitis due to its excellent antibiotic activity against
Staphylococcus that are resistant to benzylpenicillin (Amir 2014 y 2011, Spencer 2008, Nordeng 2003, Bodley 2000).

The possibility of transitory gastroenteritis due to intestinal microbiome disruption should be taken into account (Briggs 2017, Ito 1993).

Suggestions made at e-lactancia are done by APILAM team of health professionals, and are based on updated scientific publications. It is not intended to replace the relationship you have with your doctor but to compound it. The pharmaceutical industry contraindicates breastfeeding, mistakenly and without scientific reasons, in most of the drug data sheets.
