What is Neonatal Abstinence Syndrome?

Neonatal abstinence syndrome (NAS) is a collection of signs and symptoms that indicate a newborn is experiencing withdrawal from exposure to addictive opiate drugs while in the mother’s womb.   The most common opiate drugs that are associated with NAS are heroin, codeine, oxycodone (oxycontin), fentanyl, methadone and buprenorphine.  The occurrence of NAS is not limited to newborns of moms with illicit drug use, but could also be a result of pregnant women using prescribed medications for the treatment of pain, depression, and anxiety. 

baby-bottle-with-pillsWhen your baby is born, your baby is still dependent on the drug.  Because your baby is no longer getting the drug through you, the mother, via the placenta, symptoms of withdrawal may occur.  Although NAS is associated the most with opiate drugs, babies exposed to alcohol, tobacco, and other drugs can also have symptoms of withdrawal.


Why should I tell my healthcare provider if I am using drugs during my pregnancy?

It is important to be honest with your obstetrician (OB) or nurse midwife and with your baby’s pediatrician about what you were taking during your pregnancy (prescription medications, illicit drugs, tobacco, or alcohol), how much you were using and how often so the doctor can be prepared to treat your baby for withdrawal symptoms.  Because symptoms may not show up for days after delivery, it is important to watch your baby closely and call your baby’s pediatrician right away if you notice any of the symptoms of withdrawal.

What are the symptoms my baby may experience if he/she goes through withdrawal?

Symptoms of withdrawal may depend on the drug involved and the last time the drug was used.  Symptoms can begin within 1-3 days after birth, or may take up to 10 days to appear.  Symptoms include:

  • Blotchy skin coloring (mottling)
  • Diarrhea
  • Excessive crying or high-pitched crying
  • Excessive sucking
  • Fevercrying-baby
  • Hyperactive reflexes
  • Increased muscle tone
  • Irritability
  • Jitteriness
  • Poor feeding
  • Rapid breathing
  • Seizures
  • Sleep problems
  • Slow weight gain
  • Stuffy nose, sneezing
  • Sweating
  • Trembling (tremors)
  • Vomiting

What else should I know?

  • It is important to only take medication during your pregnancy that your obstetrician or nurse midwife says is okay to take during pregnancy.
  • Never take any illicit drugs, prescription drugs that were not prescribed to you or drink alcohol, smoke or be around others who are smoking during your pregnancy.
  • If you are addicted to prescription medication, alcohol, tobacco, or illicit drugs, get treatment before becoming pregnant and as soon as you find out that you are pregnant.
  • Pregnant women who use certain drugs during pregnancy may have a baby who cries more than other babies.  It is easy to become frustrated when your baby is crying.  Shaken baby syndrome is 100% preventable and there are ways to deal with your frustrations.
  • Print a brochure to keep on your refrigerator or in your nursery for when you need to remember how to cope with your child’s crying. It may also be a good idea to print a brochure with information for anyone who will care for your child like a child care provider. Coping with Crying Brochure
