Naloxone Levels and Effects while Breastfeeding
Summary of Use during Lactation
No information is available on the excretion of naloxone into breastmilk. Because it is not orally bioavailable, it is unlikely to affect the breastfed infant. However, if naloxone is required by the mother for an opiate overdose, she should withhold nursing until the opiate is out of her system.
