Very Low Risk

Safe. Compatible. Minimal risk for breastfeeding and infant.

It is assumed that excretion into breast milk achieves bacteriostatic concentrations.
A latest update no published data were found on excretion into breast milk.

Because a high molecular weight it seems unlikely an excretion into breast milk in significant amount.
A low oral bioavailability further reduced with simultaneous food intake impairs the appearance in the infant plasma from ingested milk except in preterm babies and those in the immediate neonatal period, which may have increased intestinal permeability.

Macrolide-based medication that is used in infants.
Until more published data on this drug regarding breastfeeding is available, safer alternatives with better known drugs should be preferable especially during the neonatal period and in case of prematurity..

Take into account the possible negative cultures in febrile infants whose mothers take antibiotics


  • Azithromycin ( Safe. Compatible. Minimal risk for breastfeeding and infant.)
  • Clarithromycin ( Safe. Compatible. Minimal risk for breastfeeding and infant.)
  • Pyrimethamine ( Safe. Compatible. Minimal risk for breastfeeding and infant.)

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.
