Neonatal abstinence syndrome (NAS) is a set of problems that may affect a baby if the mother used certain drugs while she was pregnant. Examples of these drugs are heroin, methadone, morphine, buprenorphine, and hydromorphone. Sometimes they are prescription medicines.
The drug passes through the mother's placenta and enters the baby's bloodstream. The baby's body gets used to the drug. After birth, when the drug starts to leave the baby's body, he or she may go through withdrawal. This may happen within hours after birth or days or weeks later. It depends on the drug.
If NAS develops, the baby may become upset and jittery or have seizures. He or she may cry a lot and have problems feeding and sleeping. And the baby may have stomach problems like vomiting and diarrhea. But most babies recover after the drug leaves their body. How long this takes depends on the drug and how much is in the body.
Follow-up care is a key part of your child's treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse advice line (811 in most provinces and territories) if your child is having problems. It's also a good idea to know your child's test results and keep a list of the medicines your child takes.
Call your doctor or nurse advice line now or seek immediate medical care if:
Watch closely for changes in the baby's health, and be sure to contact your doctor or nurse advice line if the baby has any problems.
