Neonatal Abstinence Syndrome (NAS): Babies Born Addicted

When you hear “babies born addicted,” it’s heartbreaking—and it’s also a medical condition we know how to treat. Neonatal abstinence syndrome (NAS) happens when a newborn experiences withdrawal after prenatal exposure to certain substances, most often opioids. With the right care, babies recover, and parents are supported, too. If you’re pregnant or parenting and struggling with substance use, compassionate, confidential help is available so both you and your baby can heal and thrive.

What Is Neonatal Abstinence Syndrome?

Neonatal abstinence syndrome (NAS) refers to the group of withdrawal symptoms a baby can have after being exposed to drugs in the womb. Many clinicians now use the term neonatal opioid withdrawal syndrome (NOWS) when opioids are the primary cause. Substances cross the placenta, and the baby’s body adapts; after birth, when exposure stops, withdrawal can occur.

NAS/NOWS is a treatable medical condition—not a moral failing. Rates have risen in recent years alongside the opioid crisis, but outcomes improve when families receive nonjudgmental, evidence-based care. Most babies respond well to supportive measures and, when needed, carefully managed medications.

What Causes Neonatal Abstinence Syndrome?

NAS most commonly follows exposure to opioids such as heroin, fentanyl, and prescription pain medicines (oxycodone, hydrocodone, morphine). Other substances may contribute or complicate withdrawal, including:

– Benzodiazepines (e.g., alprazolam, clonazepam)
– Certain antidepressants (SSRIs/SNRIs)
– Alcohol and other sedatives
– Stimulants (may not cause classic NAS but can affect newborn health)

Severity varies with the type of drug, dose, duration, and timing in pregnancy. Medications used in treatment programs—methadone and buprenorphine—can also lead to NAS, but typically a more predictable, manageable form. These medications are safer than ongoing illicit use and are standard of care for opioid use disorder during pregnancy.

Signs and Symptoms of Neonatal Abstinence Syndrome

Symptoms usually begin within 24–72 hours after birth but can start earlier or later (up to about a week). Some babies show mild signs; others need more intensive support. The course may last days to weeks, sometimes longer, depending on exposure and response to treatment.

Common Symptoms

– Neurological/behavioral: excessive or high-pitched crying, tremors, irritability, trouble sleeping, increased muscle tone, and in severe cases, seizures
– Gastrointestinal: poor feeding or uncoordinated suck, vomiting, diarrhea, and slow weight gain
– Autonomic: fever, sweating, yawning, sneezing, rapid breathing, nasal stuffiness, and temperature instability

Severe Complications

Possible complications include low birth weight, premature birth, dehydration from feeding issues, and rare seizure activity. A calm environment and close medical monitoring reduce risks and help babies settle. Your care team will tailor support to your baby’s unique needs.

How Is Neonatal Abstinence Syndrome Diagnosed?

Providers start with a compassionate, confidential maternal history and newborn exam. To assess severity, they may use a standardized scoring tool like the Finnegan Neonatal Abstinence Scoring System or function-based approaches such as Eat, Sleep, Console (ESC), which focus on how well a baby eats, sleeps, and is consoled. Newborn drug screening (urine, meconium, or umbilical cord tissue) may be used to guide care, not to punish. The goal is to match the right level of support and, when necessary, medication.

Treatment Options for Babies With NAS

Many babies remain with their parents in the hospital or a special care nursery/NICU for monitoring during the first days after birth. Care starts with nonpharmacologic, comfort-first strategies that can significantly reduce symptoms and length of stay.

Non-medication (first-line) care includes:
– Skin-to-skin contact, rooming-in, and frequent cuddling
– Swaddling and low-stimulation environments (dim lights, low noise)
– On-demand, frequent, smaller feedings; high-calorie formulas if needed
– Breastfeeding when appropriate and safe (see below)
– Involving parents/caregivers in soothing, ESC-based care

Medications for Severe NAS

If symptoms remain moderate to severe, providers may use:
– Opioid therapy: morphine, methadone, or buprenorphine to treat opioid withdrawal
– Adjuncts: clonidine or phenobarbital for persistent irritability, sleep difficulties, or polysubstance exposure

Medications are started at the lowest effective dose and slowly tapered as the baby stabilizes. Most infants improve steadily with a combination of comfort care and, when necessary, medication weaning.

Long-Term Effects and Prognosis

With timely, appropriate treatment, most babies with neonatal abstinence syndrome recover fully. Some children may be at higher risk for developmental, learning, or behavioral challenges, especially when other factors (prematurity, polysubstance exposure, unstable housing, or limited prenatal care) are present. Early intervention, regular pediatric follow-up, nurturing relationships, and a stable environment help children reach their milestones. Many families find that with recovery support and consistent care, their children thrive.

Preventing Neonatal Abstinence Syndrome

– Get prenatal care early. Share medications and substance use openly with a trusted provider.
– Use medication-assisted treatment (MAT). Methadone or buprenorphine during pregnancy reduces risks associated with illicit opioid use and supports stability.
– Do not quit opioids “cold turkey.” Sudden withdrawal can be unsafe in pregnancy. Always taper or transition under medical care.
– Plan pregnancies. If you use opioids or other substances and aren’t planning a pregnancy, ask about contraception.
– Seek addiction treatment. Evidence-based programs can support you before conception, during pregnancy, and postpartum—without judgment.

Support for Mothers: Your Recovery Matters Too

Your health is central to your baby’s wellbeing. Feelings of guilt or shame are common, but you deserve compassionate care. Comprehensive treatment may include inpatient or outpatient programs, MAT, counseling, peer support, and parenting resources. Postpartum mental health concerns (depression, anxiety, trauma) are treatable and often improve alongside recovery. Many programs welcome partners and family, strengthening the whole household.

Frequently Asked Questions About Neonatal Abstinence Syndrome

What is neonatal abstinence syndrome (NAS)?

NAS is a treatable condition where newborns experience withdrawal after prenatal drug exposure, most often opioids. It’s medical—not a moral failing—and with care, babies recover.

What drugs cause neonatal abstinence syndrome?

Opioids are the most common cause. Benzodiazepines, certain antidepressants, alcohol, and other sedatives can contribute or complicate symptoms.

What are the symptoms of NAS in newborns?

Irritability, excessive crying, tremors, feeding problems, vomiting/diarrhea, sweating, fever, and sleep issues. Symptoms usually begin within 1–3 days and vary in severity.

How is neonatal abstinence syndrome diagnosed?

Clinicians use maternal history, newborn exam, and tools like Finnegan or Eat, Sleep, Console. Urine, meconium, or cord tests may assist decisions—care is supportive, not punitive.

Can babies die from neonatal abstinence syndrome?

With proper hospital monitoring and treatment, death is rare. Untreated severe symptoms can be dangerous, which is why early, supportive care matters.

How long does neonatal abstinence syndrome last?

Many babies improve within days to weeks. Some need longer support, depending on exposure and response to treatment. Your team will guide expectations.

Will my baby have long-term problems from NAS?

Most recover fully. Some may face developmental or behavioral challenges; early intervention and steady pediatric follow-up reduce risks and support healthy growth.

Can I prevent neonatal abstinence syndrome?

Yes—prenatal care, MAT for opioid use disorder, avoiding abrupt withdrawal, family planning, and seeking addiction treatment all reduce NAS risk.

Should I breastfeed if I’m taking methadone or buprenorphine?

Often yes, if you’re stable in treatment and not using other unsafe substances. Breastfeeding can soothe NAS. Always confirm with your healthcare provider.
