Azithromycin’s Passage into Breast Milk: What We Know

Azithromycin does transfer into breast milk, though in relatively small amounts. Studies show detectable levels, but these are generally low compared to the mother’s serum concentration.

The concentration in breast milk peaks approximately 2-3 hours after maternal ingestion. This suggests breastfeeding mothers can minimize infant exposure by timing feedings accordingly. However, the risk to infants appears minimal in most cases.

Clinical experience demonstrates that adverse events in breastfed infants are rare. The American Academy of Pediatrics generally considers azithromycin compatible with breastfeeding. Individual risk assessments are often recommended, especially for premature babies or those with underlying health conditions.

While data suggests low risk, careful monitoring of the infant is advisable. Mothers should watch for signs of diarrhea, vomiting, or unusual fussiness. Any concerns should prompt a conversation with a healthcare provider.

Always consult your physician or lactation consultant before using azithromycin while breastfeeding. They can consider your specific circumstances and provide personalized advice.
