Neonatal Abstinence Syndrome

Neonatal Abstinence Syndrome (NAS) refers to symptoms of withdrawal that babies can develop after birth if their mothers have taken medications or drugs during their pregnancy that can be addictive.

Cause of Symptoms

Many drugs used by mothers can reach the baby while they are in the womb. Once the baby is born, they can no longer receive the drug from their mother’s body, and may develop symptoms of NAS. These symptoms may include irritability, poor feeding, fever, sweating, stuffy nose, vomiting, stiffness or seizures.

Common Drugs Reponsible

  • Narcotics: methadone, morphine, Oxycodone, Percocet and Vicodin
  • Muscle relaxants and antidepressants: Valium (diazepam), Ativan (lorazepam), Xanax
  • Other potentially addictive drugs: cocaine, heroin, ecstasy and methamphetamine

It is very important that you let your nurse and doctor know about any drugs used during your pregnancy. This will help your caregivers to give appropriate medicines to you and your baby, deliver the best care, and discharge your baby home as soon as safely possible after birth.We cannot predict which babies will have NAS. The amount of drugs or medicines that the baby receives in the womb does not always match the symptoms that each baby may have after they are born.
