Drugs and Breastfeeding

Drugs and Breastfeeding

Health benefit of breastfeeding to both mother and infant is widely accepted. Breastfeeding can reduce risk of infections as well as other diseases, such as diabetes for infants. However, many breastfeeding women are affected by health conditions and need to take medications during breastfeeding, some of which may enter into breast milk with a potential risk of toxicity to the infant. Sometimes, concerns about transfer of drugs through breast milk to the infants lead the mothers to either avoid breastfeeding or stop their medication.

Our knowledge about drug safety during breastfeeding is limited. It is important to provide safety information about drug use during breastfeeding.
