Is R 3365 Safe in Breastfeeding

I am a breastfeeding mother and i want to know if it is safe to use R 3365? Is R 3365 safe for nursing mother and child? Does R 3365 extracts into breast milk? Does R 3365 has any long term or short term side effects on infants? Can R 3365 influence milk supply or can R 3365 decrease milk supply in lactating mothers?

R 3365 is not approved for marketing in the United States by the U.S. Food and Drug Administration, but is available in other countries. Limited data indicate that the amounts of piritamide in colostrum is very low after use of intravenous piritamide by patient-controlled analgesia. In general, 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 narcotic analgesics. Once the mother's milk comes in, it is best to provide pain control with a nonnarcotic analgesic and limit maternal intake of meperidine to a few days at a low dosage with close infant monitoring. If the baby shows signs of increased sleepiness (more than usual), difficulty breastfeeding, breathing difficulties, or limpness, a physician should be contacted immediately.
