The small amounts of midazolam excreted into breastmilk would not be expected to cause adverse effects in most breastfed infants. A safety scoring system finds midazolam acceptable to use during breastfeeding.[1] Two expert panels advocates waiting for at least 4 hours after a single intravenous dose of midazolam (e.g., for endoscopy) before resuming nursing.[2,3] With a newborn or preterm infant a cautious approach would be to wait a period of 6 to 8 hours before resuming nursing. After general anesthesia, breastfeeding can resume as soon as the mother has recovered sufficiently from general anesthesia to nurse.[4-6] When a combination of anesthetic agents is used for a procedure, follow the recommendations for the most problematic medication used during the procedure. With prolonged use (days) of intravenous therapy, an active metabolite can accumulate in the mother and might affect the infant, but data in breastfeeding are lacking. Monitor the infant for sedation, poor feeding and poor weight gain.
