Neonatal Drug Withdrawal

(Neonatal Abstinence Syndrome)


Neonatal drug withdrawal occurs when a baby who has been exposed to drugs in the uterus develops withdrawal symptoms. This occurs because the baby is no longer exposed to the drug the mother was taking. This condition can be caused by medications, alcohol, and illegal drugs. It can take weeks to months for a baby to fully withdraw from a drug. Without treatment, this can be a life-threatening condition. If you used drugs during your pregnancy, tell your doctor right away. Your baby can be tested and treated after delivery.
