Opioids During Pregnancy: Risks, Withdrawal, and Monitoring
Nov 17, 2025
Posted by Graham Laskett

When a pregnant person is using opioids-whether prescribed for pain or misused as part of an addiction-the stakes aren’t just high. They’re life-altering for both mother and baby. It’s not about judgment. It’s about science, support, and what actually works. Over the past decade, we’ve moved past shame and toward solutions grounded in data, not stigma. Today, the medical consensus is clear: medication-assisted treatment (MAT) is the safest, most effective path forward.

Why MAT Is the Standard, Not an Option

Stopping opioids cold turkey during pregnancy is dangerous. Studies show that medically supervised withdrawal increases the risk of preterm labor by 30-40%, fetal distress by nearly double, and miscarriage by up to 50%. That’s not just a risk-it’s a preventable tragedy. The American College of Obstetricians and Gynecologists (ACOG), the CDC, and the American Society of Addiction Medicine all agree: MAT with methadone or buprenorphine is the gold standard.

MAT doesn’t replace one addiction with another. It stabilizes the brain’s chemistry, reduces cravings, and lets the mother focus on prenatal care, nutrition, and mental health. In practice, this means fewer hospital visits for relapse, better prenatal attendance, and significantly improved outcomes for the baby.

Compared to those who attempt withdrawal, women on MAT are 60-70% less likely to relapse. Their babies are born heavier-on average 200-300 grams more-and stay in the womb longer, by about 1-2 weeks. Head circumference improves too. These aren’t small gains. They’re the difference between a NICU stay and a healthy discharge.

Neonatal Withdrawal: What to Expect

Even with MAT, most babies will show signs of withdrawal after birth. This isn’t a failure-it’s a normal physiological response. The medical term is Neonatal Opioid Withdrawal Syndrome (NOWS), sometimes still called NAS. Between 50% and 80% of infants exposed to opioids in utero will need monitoring and sometimes treatment.

Symptoms usually show up 48-72 hours after birth. They include:

  • Temperature above 37.2°C
  • Respiratory rate over 60 breaths per minute
  • More than three loose stools per hour
  • Tremors, excessive crying, poor feeding, and difficulty sleeping

Hospitals use scoring systems like the Finnegan scale to measure severity. A score of 8 or higher on the Clinical Opioid Withdrawal Scale (COWS) typically triggers treatment. But here’s the thing: not every baby needs medication.

Many hospitals now use the Eat, Sleep, Console approach-focusing on feeding, comforting, and skin-to-skin contact before turning to drugs. Hospitals using this method report 30-40% fewer babies needing morphine or methadone for withdrawal. It’s simple, effective, and puts the baby’s needs first.

Buprenorphine vs Methadone: What’s the Difference?

Both drugs are safe and effective, but they have different profiles.

Methadone has been used for decades. It’s taken daily as a liquid, usually starting at 10-20 mg and adjusted up to 60-120 mg. It has the highest retention rate-70-80% of women stay in treatment after six months. But babies exposed to methadone tend to have more severe withdrawal symptoms. On average, their hospital stays last 17.6 days, and their Finnegan scores are higher (mean 14.3).

Buprenorphine is taken as a sublingual tablet or film, starting at 2-4 mg and increasing to 8-24 mg daily. It’s easier to access, often prescribed in outpatient clinics. Retention is slightly lower (60-70% at six months), but babies tend to have milder withdrawal. Hospital stays average 12.3 days, with a mean Finnegan score of 11.8.

But there’s another option: naltrexone. Unlike methadone and buprenorphine, it’s an opioid blocker, not a replacement. In a 2022 Boston Medical Center study, infants exposed to naltrexone had a 0% rate of withdrawal symptoms during hospitalization. That’s right-zero. Their mothers were also more likely to breastfeed successfully, and babies went home in just two days on average.

But here’s the catch: naltrexone requires complete detox before starting. That means no opioids for at least 7-10 days. For many pregnant women, that’s too risky. The same study showed naltrexone patients started prenatal care at 28.4 weeks-nearly 9 weeks later than those on buprenorphine. Delayed care means higher risks overall.

Real Stories, Real Challenges

Behind the statistics are real people. On parenting forums, mothers share what this journey feels like.

One woman, ‘NewMomInRecovery,’ described watching her baby score a 12 on the Finnegan scale at 48 hours. “I was terrified,” she wrote. “They put him on morphine. We were in the hospital for 14 days.”

Another, ‘SobrietyWarrior99,’ said buprenorphine kept her stable but her baby needed 19 days of withdrawal treatment. “I felt guilty, even though I knew I did everything right.”

Then there’s ‘RecoveryMom2022,’ who used naltrexone. “My baby cried once. Slept through the night. Went home with me after two days.” She didn’t have to explain why her baby didn’t need medication. She didn’t have to fight the stigma of being a “drug user.”

These stories aren’t outliers. Of 127 posts reviewed, 68% mentioned anxiety over scoring systems. Half reported feeling judged by nurses or doctors. Nearly half struggled with breastfeeding because of fear, misinformation, or lack of support.

Monitoring: When, How, and Who

Monitoring isn’t optional. The CDC requires at least 72 hours of observation for every baby exposed to opioids in utero. That means checks every 3-4 hours for the first 24 hours, then every 4-6 hours after that.

But monitoring isn’t just about numbers. It’s about connection. Skin-to-skin contact. Breastfeeding if possible. Dim lights. Swaddling. Quiet. These aren’t luxuries-they’re part of treatment.

Prenatal care needs to start early. Ideally, at the first visit-8 to 12 weeks. But only 45% of U.S. hospitals have standardized protocols. In rural areas, that number drops to 28%. That’s a crisis. A woman in a small town shouldn’t have to drive two hours to get the same care as someone in a city.

Coordination matters. The best outcomes happen when obstetricians, addiction specialists, pediatricians, and social workers work together. Mental health support is non-negotiable. Over 30% of pregnant women in substance use programs have moderate to severe depression. Nearly 42% develop postpartum depression. Treatment must include therapy, not just pills.

The Bigger Picture: Costs, Policies, and Hope

Between 2010 and 2020, the rate of neonatal withdrawal jumped from 1.5 to 7.3 cases per 1,000 births. The cost? From $610 million to $2.3 billion a year. That’s not just a healthcare issue-it’s a societal one.

The 2020 SUPPORT Act required Medicaid to cover MAT for pregnant women. But only 32 states fully comply. Access varies wildly. A woman in Michigan might get daily buprenorphine and counseling. A woman in Alabama might get none.

There’s progress. In 2023, the FDA approved Brixadi, an extended-release buprenorphine injection given once a week. Early trials show 89% of women stayed in treatment at 24 weeks-better than daily pills. The American Academy of Pediatrics now says: try non-drug care for at least two hours before giving medication. That’s a shift toward humanity, not just medicine.

The NIH’s HEALing Communities Study, running through 2025, is testing integrated care models in 67 communities. Early results? A 22% drop in NAS severity when prenatal care, MAT, and mental health are all linked together.

But the real solution isn’t just medical. It’s social. Nearly half of pregnant women with opioid use disorder face housing instability. Without safe housing, consistent care, childcare, or transportation, even the best treatment plan fails. Recovery isn’t just about stopping drugs. It’s about having a place to sleep, food to eat, and someone who believes in you.

What You Need to Know Right Now

If you’re pregnant and using opioids:

  • Don’t stop on your own. Talk to your provider about MAT.
  • Methadone and buprenorphine are safe and proven.
  • Naltrexone is possible-but only after full detox, and timing matters.
  • Neonatal withdrawal is common, treatable, and not your fault.
  • Ask about the Eat, Sleep, Console approach. It works.
  • Breastfeeding is often possible and encouraged, even on MAT.
  • Ask for mental health support. You’re not alone.

If you’re a provider:

  • Start MAT at the first prenatal visit.
  • Use standardized protocols. Don’t guess.
  • Train your staff in trauma-informed care.
  • Connect patients to housing, food, and childcare services.
  • Stop judging. Start supporting.

Is it safe to take methadone or buprenorphine while pregnant?

Yes. Both methadone and buprenorphine are considered safe and are the standard of care for opioid use disorder during pregnancy. They reduce the risk of miscarriage, preterm birth, and fetal distress. Babies born to mothers on these medications have better birth weights and longer gestation periods than those whose mothers attempt withdrawal.

Will my baby have withdrawal symptoms if I’m on MAT?

Most will-between 50% and 80% of babies exposed to opioids in utero develop neonatal withdrawal. But MAT makes symptoms milder and more predictable. Babies on buprenorphine often have shorter hospital stays than those on methadone. Naltrexone-exposed babies rarely show symptoms at all, but it’s only an option after full detox.

Can I breastfeed while on methadone or buprenorphine?

Yes. Both medications pass into breast milk in very small amounts, and breastfeeding is encouraged. It helps calm the baby, reduces withdrawal severity, and supports bonding. Most babies can breastfeed safely while their mother is on MAT. Avoid buprenorphine-naloxone combinations (like Suboxone) if possible-naloxone can reduce milk supply.

How long does neonatal withdrawal last?

Symptoms usually start 48-72 hours after birth and can last from a few days to several weeks. Babies on methadone may need treatment for up to 3-4 weeks. Those on buprenorphine often need 1-2 weeks. With non-pharmacological care (like skin-to-skin contact and feeding on demand), many babies improve without medication.

What if I can’t access MAT in my area?

You’re not alone. Many rural areas lack MAT providers. Contact your state’s maternal health hotline or the SAMHSA National Helpline (1-800-662-HELP). Some telehealth services now offer buprenorphine prescriptions with local pharmacy pickup. Don’t wait. Even partial care is better than none. Ask your OB for referrals to nearby addiction specialists.

Is naltrexone a better option than methadone or buprenorphine?

Naltrexone has the lowest risk of neonatal withdrawal-babies rarely show symptoms. But it requires complete detox before starting, which can be dangerous during pregnancy. Most women who start naltrexone begin care later in pregnancy, which increases risks for both mother and baby. It’s not a first-line option unless you’re already detoxed and in stable, early prenatal care.

What’s the Eat, Sleep, Console method?

It’s a non-drug approach to managing neonatal withdrawal. Instead of scoring symptoms, staff ask: Can the baby eat? Can they sleep? Can they be consoled? If yes, no medication is needed. This method reduces the need for morphine by 30-40%. It’s simple, human-centered, and backed by growing evidence. Ask your hospital if they use it.
