Is 6-Demetil-7-clorotetraciclina Safe in Breastfeeding

I am a breastfeeding mother and i want to know if it is safe to use 6-Demetil-7-clorotetraciclina? Is 6-Demetil-7-clorotetraciclina safe for nursing mother and child? Does 6-Demetil-7-clorotetraciclina extracts into breast milk? Does 6-Demetil-7-clorotetraciclina has any long term or short term side effects on infants? Can 6-Demetil-7-clorotetraciclina influence milk supply or can 6-Demetil-7-clorotetraciclina decrease milk supply in lactating mothers?

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 Withdrawn from the market in Spain.

A number of reviews have stated that tetracyclines are contraindicated during breastfeeding because of possible staining of infants' dental enamel or bone deposition of tetracyclines. However, a close examination of available literature indicates that there is not likely to be harm in short-term use of 6-Demetil-7-clorotetraciclina during lactation because milk levels are low and absorption by the infant is inhibited by the calcium in breastmilk. Short-term use of 6-Demetil-7-clorotetraciclina is acceptable in nursing mothers. As a theoretical precaution, avoid prolonged or repeat courses during nursing. Monitor the infant for rash and for possible effects on the gastrointestinal flora, such as diarrhea or candidiasis (thrush, diaper rash).
