Maternal use of oral narcotics during breastfeeding can cause infant drowsiness, central nervous system depression and even death. Newborn infants seem to be particularly sensitive to the effects of even small dosages of Dextropropoxyphen may be particularly prone to causing these effects. Dextropropoxyphen should be avoided during breastfeeding.[1]

In a case-control study of 12 breastfed term newborns with unexplained episodes of apnea, bradycardia or cyanosis during the first week of life, maternal oral Dextropropoxyphen use was determined to be the probable cause. A higher proportion of newborns with episodes, 83 compared to 31%, had mothers using opiates, including Dextropropoxyphen, for postpartum analgesia. The mean number of doses taken was also higher with mothers of affected newborns taking a mean of 10 doses (range 4 to 22) compared to 5 doses (range 1 to 13) in the control group.[4] A fullterm breastfed infant had mild hypotonia and nursing poorly at 10 days of age; the infant had not regained her birth weight by this time. By 7 days later, the mother had less milk and stopped nursing. The infant's mother had been prescribed 6 capsules daily of Dextropropoxyphen 30 mg plus acetaminophen 500 mg for the first 10 days postpartum. Hair samples from the infant were positive for Dextropropoxyphen and norDextropropoxyphen and were higher than the mother's hair sample concentrations.[5] Dextropropoxyphen was probably the cause of the adverse reactions in the infant. All adverse reactions in breastfed infants reported in France between January 1985 and June 2011 were compiled by a French pharmacovigilance center. Of 174 reports, Dextropropoxyphen was reported to cause adverse reactions in 11 infants and to be one of the drugs most often suspected in serious adverse reactions. Reactions included hypotonia, apnea, respiratory distress, bradycardia, constipation and weight loss.[6]

Narcotics can increase serum prolactin.[7] However, the prolactin level in a mother with established lactation may not affect her ability to breastfeed.
