Neonatal Abstinence Syndrome
What is neonatal abstinence syndrome?
Neonatal abstinence syndrome is what happens when babies are exposed to drugs in the
womb before birth. Babies can then go through drug withdrawal after birth.
What causes neonatal abstinence syndrome?
Almost every drug and medicine passes from the mother’s bloodstream through the placenta
to her unborn baby. If the mother uses street drugs, it can also cause the unborn
baby to become addicted. At birth, the baby continues to need the drug. But because
the drug is no longer available, the baby goes through withdrawal.
Some drugs and medicines are more likely to cause the syndrome than others. But nearly
all have some effect on the baby. These include:
- Opiates like heroin and prescribed medicines such as codeine and oxycodone
- Amphetamines such as cocaine
- Barbiturates such as marijuana
Alcohol use also causes withdrawal in the baby. It also can cause another groups of
problems called fetal alcohol spectrum disorders.
Who is at risk for neonatal abstinence syndrome?
Pregnant women who use drugs or drink alcohol put their unborn babies at risk for
neonatal abstinence syndrome and other problems. Women who use drugs also may be less
likely to get prenatal care. This can also increase the risks for both mother and
What are the symptoms of neonatal abstinence syndrome?
Symptoms of the syndrome may vary depending on:
- The type of drug used
- The last time it was used
- Whether the baby is full-term or premature
Symptoms of withdrawal may start as soon as 24 to 48 hours after birth. Or they may
start as late as 5 to 10 days after birth.
The following are the most common symptoms of the syndrome. Symptoms may be slightly
different for each baby. Symptoms of withdrawal in full-term babies may include:
- Too much crying or high-pitched crying
- Sleep problems
- Tight muscle tone
- Overactive reflexes
- Yawning, stuffy nose, and sneezing
- Poor feeding and sucking
- Vomiting or diarrhea
- Fever or unstable temperature
Premature babies may have a lower risk for withdrawal symptoms or have less severe
symptoms. They may also get better faster because they were exposed to less of the
drug than full-term babies.
The symptoms of this problem may look like other health conditions. Make sure your
child sees his or her healthcare provider for a diagnosis.
How is neonatal abstinence syndrome diagnosed?
The diagnosis is made based on a history of substance abuse in the mother. An accurate
report of the mother’s drug use is important. This includes the time the last drug was taken.
The healthcare provider may use a scoring system to help diagnose and pinpoint how
serious the baby’s withdrawal is. Points are assigned for certain signs and symptoms
and the seriousness of each. This scoring may also help in planning treatment.
The healthcare provider may check meconium or urine samples if the provider suspects
that the mother was using drugs. It can also be done if the baby shows symptoms of
How is neonatal abstinence syndrome treated?
Treatment will depend on your child’s symptoms, age, and general health. It will also
depend on how severe the condition is.
Babies suffering from withdrawal are irritable. They often have a difficult time being
comforted. Wrapping the baby snugly in a blanket may help give comfort. Babies also
may need extra calories because of their increased activity. They may need a higher
calorie formula. They may also need IV fluids if they are dehydrated or have severe
vomiting or diarrhea.
Some babies may need medicines to treat severe withdrawal symptoms such as seizures.
Medicines may also help relieve the discomfort and problems of withdrawal. Babies
will usually be given a medicine that is in the same family of drugs as the drug the
baby is withdrawing from. Once the signs of withdrawal are controlled, the amount
of the medicine is slowly decreased. This helps wean the baby off the drug. Talk with
your baby's healthcare provider to learn which treatments might work for your baby.
What are the complications of neonatal abstinence syndrome?
In addition to the problems of withdrawal after birth, complications in the baby may
- Poor growth in the uterus
- Being born to soon
- Birth defects
Specific drugs can cause specific problems in the baby. These problems may include:
- Heroin and other opiates, including methadone, can cause serious withdrawal in the
baby. Some symptoms can last as long as 4 to 6 months. Seizures may also occur in
babies born to methadone users.
- Amphetamines can lead to low birth weight and premature birth.
- Cocaine use can cause poor growth, developmental delay, learning disabilities, and
lower IQ in the baby.
- Marijuana use may cause lower birth weight.
- Alcohol use can have major effects on babies before and after birth. Growth during
pregnancy and after birth is slowed. It can also cause certain problems of the head
and face, heart defects, and mental problems.
- Cigarette smoking may cause low birth weight. It may also put babies at higher risk
for premature birth and stillbirth.
Can neonatal abstinence syndrome be prevented?
This syndrome is a very preventable problem. But it can only be prevented if the mother
stops using drugs before pregnancy or as soon as she learns she is pregnant.
