Drug Levels and Effects
Summary of Use during Lactation
No information is available on the clinical use of flumazenil during breastfeeding. Because flumazenil is not orally absorbed it is unlikely to adversely affect the breastfed infant. If the mother requires flumazenil, it is not a reason to discontinue breastfeeding. The half-life of the drug is 54 minutes, so withholding breastfeeding for 4 to 5 hours after a dose should minimize transfer to the infant.
