The levels of zolpidem in breastmilk are low and is somewhat rapidly eliminated from milk, so it would not be expected to cause any adverse effects in older breastfed infants who does not breastfeed during the night after the mother’s dose. The manufacturer states that excess sedation in infants exposed to zolpidem through breastmilk has been reported, although details are lacking. Some expert opinion recommends against zolpidem use during breastfeeding, primarily because of minimal documentation.[1] Monitor the infant for sedation, poor feeding and poor weight gain.
