Levels in milk
Maternal Levels. Twenty women undergoing cesarean section received 0.3 mg/kg of etomidate intravenously for induction of anesthesia. Average colostrum levels were 79.3 mcg/L (range 0 to 420 mcg/L) at 30 minutes and 16.2 mcg/L (range 0 to 60 mcg/L) at 2 hours after the dose. Etomidate was not detected in any colostrum samples 4 hours after the dose.[ 1 ] Infant Levels. Relevant published information was not found as of the revision date.
Alternatives LactMed lists
“No published information” means the studies do not exist yet — not that Etomidate is known to be harmful, and not that it is known to be safe. Your prescriber or pharmacist can weigh your baby's age and whether a better-studied alternative would do the same job. Worth asking before stopping a medicine you need.
