Is Vecuronium safe while breastfeeding?

Summary of use during breastfeeding

No information is available on the use of vecuronium during breastfeeding Because it is short acting, highly polar and poorly absorbed orally, it is not likely to reach the breastmilk in high concentration or to reach the bloodstream of the infant.[1,2] When a combination of anesthetic agents is used for a procedure, follow the recommendations for the most problematic medication used during the procedure. General anesthesia for cesarean section using vecuronium as a component may delay the onset of lactation.

Effects on milk supply

A randomized study compared the effects of cesarean section using general anesthesia, spinal anesthesia, or epidural anesthesia, to normal vaginal delivery on serum prolactin and oxytocin as well as time to initiation of lactation. General anesthesia was performed using propofol 2 mg/kg and rocuronium 0.6 mg/kg for induction, followed by sevoflurane and rocuronium 0.15 mg/kg as needed. After delivery, patients in all groups received an infusion of oxytocin 30 international units in 1 L of saline, and 0.2 mg of methylergonovine if they were not hypertensive. Fentanyl 1 to 1.5 mcg/kg was administered after delivery to the general anesthesia group. Patients in the general anesthesia group (n = 21) had higher post-procedure prolactin levels and a longer mean time to lactation initiation (25 hours) than in the other groups (10.8 to 11.8 hours). Postpartum oxytocin levels in the nonmedicated vaginal delivery group were higher than in the general and spinal anesthesia groups.[3]
