Is 6-Hydroxy-8-((1R)-1-hydroxy-2-((2-(4-methoxyphenyl)-1,1-dimethylethyl)amino)ethyl)-2H-1,4-benzoxazin-3(4H)-one Safe in Breastfeeding

I am a breastfeeding mother and i want to know if it is safe to use 6-Hydroxy-8-((1R)-1-hydroxy-2-((2-(4-methoxyphenyl)-1,1-dimethylethyl)amino)ethyl)-2H-1,4-benzoxazin-3(4H)-one? Is 6-Hydroxy-8-((1R)-1-hydroxy-2-((2-(4-methoxyphenyl)-1,1-dimethylethyl)amino)ethyl)-2H-1,4-benzoxazin-3(4H)-one safe for nursing mother and child? Does 6-Hydroxy-8-((1R)-1-hydroxy-2-((2-(4-methoxyphenyl)-1,1-dimethylethyl)amino)ethyl)-2H-1,4-benzoxazin-3(4H)-one extracts into breast milk? Does 6-Hydroxy-8-((1R)-1-hydroxy-2-((2-(4-methoxyphenyl)-1,1-dimethylethyl)amino)ethyl)-2H-1,4-benzoxazin-3(4H)-one has any long term or short term side effects on infants? Can 6-Hydroxy-8-((1R)-1-hydroxy-2-((2-(4-methoxyphenyl)-1,1-dimethylethyl)amino)ethyl)-2H-1,4-benzoxazin-3(4H)-one influence milk supply or can 6-Hydroxy-8-((1R)-1-hydroxy-2-((2-(4-methoxyphenyl)-1,1-dimethylethyl)amino)ethyl)-2H-1,4-benzoxazin-3(4H)-one decrease milk supply in lactating mothers?

Although no published data exist on the use of 6-Hydroxy-8-((1R)-1-hydroxy-2-((2-(4-methoxyphenyl)-1,1-dimethylethyl)amino)ethyl)-2H-1,4-benzoxazin-3(4H)-one during lactation, data from the related drug, terbutaline, indicate that very little is expected to be excreted into breastmilk.[1] The authors of several reviews agree that use of inhaled bronchodilators is acceptable during breastfeeding because of the low bioavailability and maternal serum levels after use.[2][3][4][5]
