Macrolide antibiotic authorised for use in paediatrics. Commonly used in young infants. Oral administration in two or more daily doses.
At the date of the last update, we found no published data on its excretion in breast milk.
It has a higher molecular weight and shorter elimination half-life than other macrolides (azithromycin, clarithromycin) that are excreted in insignificant amounts in breast milk. It is much more lipophilic than erythromycin.
Until more published data on this drug in relation to breastfeeding is available, safer known alternatives may be preferable, especially during the neonatal period and in cases of prematurity.
Early exposure to macrolides (especially erythromycin) has been linked to the onset of hypertrophic pyloric stenosis, even through breast milk, so it may be prudent to avoid them during the first month of breastfeeding.
