Is (6R,7R)-7-((R)-2-(4-Ethyl-2,3-dioxo-1-piperazinylcarboxamido)-2-(4-hydroxyphenyl)acetamido)-3-((1-methyl-1H-tetrazol-5-yl)thiomethyl)-8-oxo-5-thia-1-azabicyclo(4.2.0)oct-2-en-2-carbonsaeure Safe in Breastfeeding

I am a breastfeeding mother and i want to know if it is safe to use (6R,7R)-7-((R)-2-(4-Ethyl-2,3-dioxo-1-piperazinylcarboxamido)-2-(4-hydroxyphenyl)acetamido)-3-((1-methyl-1H-tetrazol-5-yl)thiomethyl)-8-oxo-5-thia-1-azabicyclo(4.2.0)oct-2-en-2-carbonsaeure? Is (6R,7R)-7-((R)-2-(4-Ethyl-2,3-dioxo-1-piperazinylcarboxamido)-2-(4-hydroxyphenyl)acetamido)-3-((1-methyl-1H-tetrazol-5-yl)thiomethyl)-8-oxo-5-thia-1-azabicyclo(4.2.0)oct-2-en-2-carbonsaeure safe for nursing mother and child? Does (6R,7R)-7-((R)-2-(4-Ethyl-2,3-dioxo-1-piperazinylcarboxamido)-2-(4-hydroxyphenyl)acetamido)-3-((1-methyl-1H-tetrazol-5-yl)thiomethyl)-8-oxo-5-thia-1-azabicyclo(4.2.0)oct-2-en-2-carbonsaeure extracts into breast milk? Does (6R,7R)-7-((R)-2-(4-Ethyl-2,3-dioxo-1-piperazinylcarboxamido)-2-(4-hydroxyphenyl)acetamido)-3-((1-methyl-1H-tetrazol-5-yl)thiomethyl)-8-oxo-5-thia-1-azabicyclo(4.2.0)oct-2-en-2-carbonsaeure has any long term or short term side effects on infants? Can (6R,7R)-7-((R)-2-(4-Ethyl-2,3-dioxo-1-piperazinylcarboxamido)-2-(4-hydroxyphenyl)acetamido)-3-((1-methyl-1H-tetrazol-5-yl)thiomethyl)-8-oxo-5-thia-1-azabicyclo(4.2.0)oct-2-en-2-carbonsaeure influence milk supply or can (6R,7R)-7-((R)-2-(4-Ethyl-2,3-dioxo-1-piperazinylcarboxamido)-2-(4-hydroxyphenyl)acetamido)-3-((1-methyl-1H-tetrazol-5-yl)thiomethyl)-8-oxo-5-thia-1-azabicyclo(4.2.0)oct-2-en-2-carbonsaeure decrease milk supply in lactating mothers?

Limited information indicates (6R,7R)-7-((R)-2-(4-Ethyl-2,3-dioxo-1-piperazinylcarboxamido)-2-(4-hydroxyphenyl)acetamido)-3-((1-methyl-1H-tetrazol-5-yl)thiomethyl)-8-oxo-5-thia-1-azabicyclo(4.2.0)oct-2-en-2-carbonsaeure 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. (6R,7R)-7-((R)-2-(4-Ethyl-2,3-dioxo-1-piperazinylcarboxamido)-2-(4-hydroxyphenyl)acetamido)-3-((1-methyl-1H-tetrazol-5-yl)thiomethyl)-8-oxo-5-thia-1-azabicyclo(4.2.0)oct-2-en-2-carbonsaeure is acceptable in nursing mothers.
