Very Low Risk for breastfeeding

Safe. Compatible.
Not risky for breastfeeding or infant.

Macrolide with actions and uses similar to those of erythromycin.
Oral administration once a day.

Excreted in very low levels into breast milk (Sutton 2015, Salman 2015, Kelsey 1994) and no problems have been observed in infants whose mothers have taken it (Goldstein 2009).

Commonly used for pediatric treatment.

Expert authors consider Azithromycin compatible with breastfeeding (Butler 2014, Kong 2013, Khrianin 2010, Chen 2010, Goldstein 2009, Mahadevan 2006, Bar-Oz 2003, Chin 2001).

Early exposition (first 15 days of life) to Macrolides (mostly Erythromycin) have been related to hypertrophic pyloric stenosis ( Lund 2014, Maheshwai 2007, Sørensen 2003), but not others, and less for Azithromycin (Goldstein 2009, Maheshwai 2007).

Be aware of false negative bacterial cultures in the infant when the mother is on antibiotics. Also, diarrheal disease due to imbalance of intestinal flora is possible.

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