Question

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

Answer by DrLact: About beta-L-Thymidine usage in lactation

beta-L-Thymidine has not been studied in nursing mothers being treated for hepatitis B infection. An alternate drug may be preferred, especially while nursing a newborn or preterm infant. No difference exist in infection rates between breast-fed and formula-fed infants born to hepatitis B-infected women, as long as the infant receives hepatitis B immune globulin and hepatitis B vaccine at birth. Mothers with hepatitis B are encouraged to breastfeed their infants after their infants receive these preventative measures.[1][2]
