I am a breastfeeding mother and i want to know if it is safe to use 7-(1-(1H-)-Tetrazolylacetamido)-3-(2-(5-methyl-1,3,4-thiadiazolyl)thiomethyl)delta3-cephem-4-carboxylic acid? Is 7-(1-(1H-)-Tetrazolylacetamido)-3-(2-(5-methyl-1,3,4-thiadiazolyl)thiomethyl)delta3-cephem-4-carboxylic acid safe for nursing mother and child? Does 7-(1-(1H-)-Tetrazolylacetamido)-3-(2-(5-methyl-1,3,4-thiadiazolyl)thiomethyl)delta3-cephem-4-carboxylic acid extracts into breast milk? Does 7-(1-(1H-)-Tetrazolylacetamido)-3-(2-(5-methyl-1,3,4-thiadiazolyl)thiomethyl)delta3-cephem-4-carboxylic acid has any long term or short term side effects on infants? Can 7-(1-(1H-)-Tetrazolylacetamido)-3-(2-(5-methyl-1,3,4-thiadiazolyl)thiomethyl)delta3-cephem-4-carboxylic acid influence milk supply or can 7-(1-(1H-)-Tetrazolylacetamido)-3-(2-(5-methyl-1,3,4-thiadiazolyl)thiomethyl)delta3-cephem-4-carboxylic acid decrease milk supply in lactating mothers?

First-generation cephalosporin for injection or parenteral administration. Like most cephalosporins for which data are available, excretion occurs in breast milk in very small amount and it is clinically insignificant (Fukada 1973, Yoshioka 1979, Zhang 1997). Cephalosporins are widely used in the Pediatric practice with a good tolerance, even in the neonatal period, so it is very unlikely that in small amounts through milk would be a cause of problems in the infant. Be aware of the possibility of false negative results of cultures in febrile infants whose mothers are taking antibiotics as well as the possibility of gastroenteritis (Ito 1993) by altering the intestinal flora.

Limited information indicates 7-(1-(1H-)-Tetrazolylacetamido)-3-(2-(5-methyl-1,3,4-thiadiazolyl)thiomethyl)delta3-cephem-4-carboxylic acid produces low levels in milk that are not expected to cause adverse effects in breastfed infants. Occasionally disruption of the infant's gastrointestinal flora, resulting in diarrhea or thrush have been reported with cephalosporins, but these effects have not been adequately evaluated. 7-(1-(1H-)-Tetrazolylacetamido)-3-(2-(5-methyl-1,3,4-thiadiazolyl)thiomethyl)delta3-cephem-4-carboxylic acid is acceptable in nursing mothers.
