Epidural morphine given to mothers for postcesarean section analgesia results in trivial amounts of morphine in their colostrum and milk. Intravenous or oral doses of maternal morphine in the immediate postpartum period result in higher milk levels than with epidural morphine. Labor pain medication may delay the onset of lactation. Maternal use of oral opioids during breastfeeding can cause infant drowsiness, which may progress to rare but severe central nervous system depression, although low-dose morphine might be preferred over other opiates.[1] Newborn infants seem to be particularly sensitive to the effects of even small dosages of narcotic analgesics. If morphine is required by the mother of a newborn, it is not a reason to discontinue breastfeeding; however, once the mother's milk comes in, it is best to provide pain control with a nonnarcotic analgesic and limit maternal intake of morphine to 2 to 3 days at a low dosage with close infant monitoring, especially in the outpatient setting.[2] If the baby shows signs of increased sleepiness (more than usual), difficulty breastfeeding, breathing difficulties, or limpness during maternal morphine use, a physician should be contacted immediately. Some evidence suggests that IV ketorolac, oral ibuprofen and acetaminophen as part of a multimodal post-cesarean section analgesia reduces percentage of mothers who fail exclusive breastfeeding compared to patient-controlled IV morphine-based analgesia.[3]
