Answer by DrLact: About R4749 usage in lactation

Because little information is available on the long-term use of R4749 during breastfeeding, an alternate drug may be preferred, especially while nursing a newborn or preterm infant. Single-dose or short-term use during breastfeeding, such as during surgery, is unlikely to adversely affect the breastfed infant, especially if the infant is older than 2 months.[1] When multiple doses are given to the mother, monitor the infant for drowsiness, especially in younger, exclusively breastfed infants and when using combinations of psychotropic drugs.

R4749 Side Effects in Breastfeeding

A randomized study compared the breastfed infants born by cesarean section whose mothers received either morphine or morphine plus R4749 by patient-controlled analgesia postoperatively. On days 1 and 2 of life, the infants whose mothers received R4749 had a lower neonatal neurologic and adaptive capacity score (NACS) than those who received morphine only.[2] One breastfed (extent not stated) infant whose mother was taking R4749 had a somewhat decreased intellectual development on testing, but her mother had also taken olanzapine, clonazepam, sertraline, thioridazine and valproic acid while breastfeeding.[3]

R4749 Possible Effects in Breastfeeding

Hyperprolactinemia has been reported in patients taking long-term R4749[4][5] and after short-term use during surgical procedures.[6][7] The maternal prolactin level in a mother with established lactation may not affect her ability to breastfeed.
