Is Amoxicillin compatible with breastfeeding? Do we have alternatives for Amoxicillin?


February 28, 2018 (Very Low Risk)

It is excreted in breast milk in insignificant amounts and no problems have been observed in the majority of infants of mothers who took it (Golstein, 2000, Kafetzis 1981, Ito 1993, Nau 1987) except for occasional episodes of mild diarrhea, rash or drowsiness that did not require medical attention (Goldstein 2009, Benyamini 2005, Ito 1993).

It is considered medication compatible with breastfeeding by relevant authors and scientific societies (Rowe 2013, Nahum 2006, Mahadevan 2006, Bar-Oz 2003, CDC 2001, Chin 2000, Fulton 1992).

It is a medication commonly used in Pediatrics and considered an essential medicine for pediatric use by WHO (WHO 2013).

The possible negativity of cultures in febrile infants whose mothers take antibiotics should be taken into account, as well as the possibility of gastroenteritis due to altered intestinal flora (Benyamini 2005, Ito 1993, Kafetzis 1981).

American Academy of Pediatrics: medication usually compatible with breastfeeding (AAP 2001).
List of WHO essential medicines: compatible with breastfeeding (WHO / UNICEF 2002).


We do not have alternatives for Amoxicillin since it is relatively safe.
