How long does azithromycin stay in breastmilk?

Understanding Azithromycin and Its Presence in Breast Milk
Azithromycin, a widely used antibiotic, is often prescribed for various bacterial infections. For breastfeeding mothers, a common concern is how this medication affects breast milk and, consequently, their infants.
How Long Does Azithromycin Stay in Breast Milk?
Research indicates that azithromycin does pass into breast milk, but in relatively small amounts. A notable study involving a lactating woman who took a standard dose of 500 mg per day showed that the concentration of azithromycin in her breast milk was measured at 1.3 mcg/mL one hour after the first dose and 2.8 mcg/mL thirty hours after the third dose. This suggests that while azithromycin does enter breast milk, the levels are low and may not pose significant risks to a breastfeeding infant.
Safety Considerations
The consensus among healthcare professionals is that azithromycin is generally considered safe for use during lactation. The small amounts that transfer into breast milk are unlikely to cause adverse effects in healthy infants. However, as with any medication, it is crucial for breastfeeding mothers to consult with their healthcare provider before starting treatment. This ensures that both the mother’s health and the baby’s safety are prioritized.
Conclusion
In summary, azithromycin does remain in breast milk for a period, with detectable levels persisting for at least 30 hours after dosing. However, the concentrations are low, and the medication is deemed safe for breastfeeding mothers when prescribed appropriately. As always, individual circumstances can vary, so medical advice tailored to the specific situation is essential.
