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.

Withdrawn from the market in Spain.
