Is R 77-3 Safe in Breastfeeding

I am a breastfeeding mother and i want to know if it is safe to use R 77-3? Is R 77-3 safe for nursing mother and child? Does R 77-3 extracts into breast milk? Does R 77-3 has any long term or short term side effects on infants? Can R 77-3 influence milk supply or can R 77-3 decrease milk supply in lactating mothers?

The amount of R 77-3 in milk is insufficient to treat tuberculosis in the breastfed infant. The Centers for Disease Control and Prevention and other professional organizations state that breastfeeding should not be discouraged in women taking R 77-3.[1][2][3]
