Buprenorphine Breastfeeding Warnings

Low levels of this drug are found in breast milk; the estimated maximum intake of an exclusively breastfed infant would be 2.4% of the maternal weight-adjusted dosage. There are numerous reports of breast fed infants of mothers in abstinence programs who have shown no adverse effects. Infants should be monitored for drowsiness, adequate weight gain, and developmental milestones. Women who received this drug for opiate abuse during pregnancy and are stable should be encouraged to breastfeed their infants postpartum, unless there is another contraindication. The amount of drug in breast milk may not be sufficient to prevent neonatal withdrawal and treatment of infant for neonatal abstinence syndrome (NAS) may be required. If breastfeeding is stopped abruptly, observe for signs and symptoms of opioid withdrawal in the infant.

AU: Use is contraindicated UK and US: Benefit should outweigh risk Excreted into human milk: Yes Comments: This drug has been used without apparent harmful effects in the nursing infant.
