Although it is secreted into breast milk it has not been detected in infant’s blood because it forms unabsorbable chelate compounds with milk calcium. It is not recommended a long-term use (more than 3-4 weeks) since damage on bone growth plates, teeth discoloration, or alteration of intestinal flora may occur.

Be aware of the possibility of false negative results of bacterial cultures when the mother is on antibiotics.

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.
