Azithromycin, the active ingredient in Zithromax, transfers to breast milk primarily through passive diffusion. This means the drug moves from your bloodstream into your breast milk based on concentration differences. Higher levels of azithromycin in your blood lead to higher levels in breast milk.
Absorption by the Infant: The amount of azithromycin an infant absorbs depends on factors like the infant’s age, weight, and how much breast milk they consume. Premature infants may absorb a higher proportion relative to their body weight compared to full-term babies.
Factors influencing transfer: Several things affect the concentration in your milk. These include your dosage, the frequency of your doses, and how well your body absorbs and processes the medication. Consult your doctor to discuss dosage adjustments if breastfeeding.
Monitoring: While generally considered safe, monitoring your infant for potential side effects is crucial. These might include diarrhea, vomiting, or thrush. Promptly report any concerns to your pediatrician.
Data variations: Studies show variability in azithromycin concentrations in breast milk. This highlights the individual differences in drug metabolism and transfer rates.
Expert advice: Always discuss medication use while breastfeeding with your doctor or a lactation consultant. They can provide personalized guidance based on your specific circumstances and health.
