What is Neonatal Opioid Withdrawal Syndrome (NOWS)?

Neonatal Opioid Withdrawal Syndrome (NOWS) occurs in newborns whose mothers took opioid medications or illicit opioids some time while pregnant. During pregnancy, most substances taken by the mother will pass through the placenta and into the baby’s blood stream. This exposes the baby to whatever chemicals are found in drugs and medications. After birth, the baby is suddenly cut off from those medications or drugs and this can cause withdrawal symptoms.
Some babies exposed to opioids before birth will experience withdrawal while others will not and the severity of symptoms may vary. The type and severity of symptoms may be affected by
  • exposure to other drugs/substances (like cigarettes or alcohol)
  • the duration, degree, timing, and type of opioid exposure
  • the mother’s and infant’s metabolism
  • other unknown factors
This page will help you learn about NOWS and provide you with some tips on how to console a baby experiencing symptoms of NOWS.
