​Frequently Asked Questions About Substance Abuse Treatment for Expectant Mothers

UPMC Content 2


Neonatal Abstinence Syndrome (NAS) is the presence of drug withdrawal symptoms in a newborn. The severity of symptoms depend on a number of factors including the mother’s regular dose size, how long the mother has been using, type of substance used, and date of last dose.


Typically, an infant will begin showing withdrawal symptoms anywhere from 24 to 48 hours after birth, but can show symptoms as late as five to ten days.


Types of symptoms may include:

  • Irritability or fussy behavior
  • Difficulty being comforted
  • Blotchy skin
  • Rapid breathing
  • Continuous or high-pitched crying
  • Tremors or seizures
  • Diarrhea, vomiting, or dehydration
  • Fever
  • Difficulty breastfeeding

An NAS assessment of withdrawal is made based on symptom type and severity. If necessary, a baby may need medication or an IV to replenish hydration, or may stay longer in a special care setting. All infants, whether they are taking medication or not, will be under continuous observation.


To help alleviate an infant’s discomfort, a parent or relative can try wrapping the baby in swaddling blankets, reducing noise or bright lights, or rocking or soothing the baby. A physician should be consulted if additional help is needed or concerns arise.
