Suboxone during pregnancy: safety and options

Medically reviewed by [Reviewer name, credentials] · Last updated October 17, 2026

Two pink lines. For a lot of people, that moment brings a rush of joy, nerves, or both. If you have been taking Suboxone for opioid use disorder, a third feeling often slips in right behind them: worry about whether your medicine is hurting the baby.

Here is the short version. Staying on Suboxone during pregnancy is generally safer for you and your baby than stopping, and major medical groups recommend medication treatment over detox. The rest of this guide explains why, what recent research changed, and what each stage from first trimester to first months home tends to look like.

Why medication beats detox in pregnancy

It may feel natural to want every drug out of your system while pregnant. With opioid use disorder, though, the math works the other way. The American College of Obstetricians and Gynecologists (ACOG) recommends medication, either buprenorphine or methadone, rather than medically supervised withdrawal. SAMHSA’s guidance points the same direction.

The reason comes down to stability. Tapering off opioids during pregnancy is linked with high rates of return to use. Each return brings unpredictable doses, often of street drugs contaminated with fentanyl. That creates swings between intoxication and withdrawal, and those swings stress the placenta and the baby.

Buprenorphine, the main ingredient in Suboxone, smooths those swings out. A steady daily dose holds opioid receptors at an even level, so cravings ease and withdrawal stays away. It also brings you into regular contact with care, which tends to mean better prenatal visits, nutrition, and planning.

Picture a rope bridge over a river. Detox in pregnancy is like cutting the ropes partway across and hoping you swim well. Treatment keeps the bridge intact until you and the baby reach the other side, and only then do you and your care team think about the next steps.

What untreated opioid use can mean

Research has tied untreated opioid use disorder in pregnancy to a list of problems. These include poor fetal growth, preterm birth, placental problems, infection from injection, missed prenatal care, and maternal overdose. Treatment does not erase every risk, but it lowers many of them.

Is Suboxone safe during pregnancy? The 2024 shift

For years, many clinicians switched pregnant patients from Suboxone (buprenorphine plus naloxone) to a buprenorphine-only product, often called by its old brand name Subutex. That habit came from caution, not proof of harm. There simply wasn’t much data on naloxone exposure in the womb.

Naloxone is in Suboxone to discourage injection. Taken under the tongue as directed, very little of it gets absorbed. Still, “very little” was not the same as “studied,” so the single-ingredient product became the default.

That changed with a large study published in JAMA in 2024 by Straub and colleagues. The team looked at U.S. Medicaid records from 2000 to 2018 and compared pregnancies exposed in the first trimester to the combination versus buprenorphine alone.

Study detail	What the JAMA 2024 study found
Pregnancies on buprenorphine + naloxone	3,369
Pregnancies on buprenorphine alone	5,326
Data source	U.S. Medicaid claims, 2000 to 2018
Neonatal abstinence syndrome	Lower risk with the combination
NICU admission	Lower risk with the combination
Small for gestational age	Lower risk with the combination
Serious maternal health problems	Similar: about 2.6% vs 2.9%
Authors’ conclusion	Both products are reasonable options in pregnancy

This was an observational study, so it can’t prove the combination caused the better outcomes. It does strongly suggest that the naloxone in Suboxone is not a hidden danger. In practice, that means many people who are already stable on Suboxone while pregnant can stay on it rather than switching mid-pregnancy.

Your prescriber may still prefer one product for reasons specific to you, such as insurance, availability, or how well you tolerate each. For a side-by-side look at the two products outside pregnancy, see Suboxone vs Subutex and buprenorphine vs Suboxone.

Buprenorphine vs methadone in pregnancy

Methadone has the longest track record in pregnancy and remains an excellent choice. Buprenorphine has caught up as a first-line option, partly because of a landmark study known as the MOTHER trial.

Published in the New England Journal of Medicine in 2010, MOTHER randomly assigned pregnant people to buprenorphine or methadone. Babies exposed to buprenorphine needed less morphine to treat withdrawal and had shorter hospital stays than babies exposed to methadone.

Factor	Buprenorphine (Suboxone, buprenorphine-only)	Methadone
How it acts	Partial opioid agonist with a ceiling on breathing effects when used alone	Full opioid agonist
Where you get it	Prescription filled at a regular pharmacy; any clinician with the right DEA registration can prescribe	Usually daily dosing at a certified opioid treatment program, at least at first
Newborn withdrawal	Tends to be milder and shorter in studies like MOTHER	Common; may need longer treatment
Starting it	Must wait for some withdrawal to avoid precipitated withdrawal	Can start without waiting for withdrawal
Staying in treatment	In MOTHER, more people left the buprenorphine group	Structured daily visits may help some people stay engaged
Best fit	People who are stable or want office-based care	People who need more structure or did not do well on buprenorphine

Neither drug is “the right one” for everyone. The best medicine is the one you can take consistently through pregnancy and beyond. Our deeper comparisons of methadone vs buprenorphine and Suboxone vs methadone cover the non-pregnancy details.

Suboxone during pregnancy, trimester by trimester

Every pregnancy is different, but certain themes show up at predictable points. Use this as a map for questions to bring to your appointments, not a schedule to follow on your own.

First trimester: connect your care teams

The first job is getting your Suboxone prescriber and your prenatal provider talking to each other. Sign a release so they can share notes. Some clinics offer both services under one roof, which makes life easier.

• Ask whether your current product and dose should stay the same.
• Tell your prenatal team about every other medicine, including anything for anxiety, sleep, or nausea.
• Morning sickness can make it hard to keep a film under your tongue. If you vomit soon after a dose, call your prescriber instead of guessing about a repeat dose.
• Get screened for hepatitis B and C and HIV, which is standard for anyone with a history of opioid use.
• Book a dental check. The FDA has warned about tooth decay with buprenorphine that dissolves in the mouth, and pregnancy itself can make gums more fragile. See our guide on Suboxone tooth decay.

Second trimester: steady and planning

This is often the calmest stretch. Nausea usually eases, energy returns, and it’s a good time to plan for delivery and the newborn period.

• Ask your hospital whether it uses the Eat, Sleep, Console approach for newborns (more on that below).
• Meet with a pediatrician or ask for a prenatal consult with the newborn team.
• Talk through your plans for breastfeeding.
• Keep an eye on common side effects like constipation, which pregnancy and buprenorphine can both worsen. Our Suboxone side effects guide has tips.

Suboxone third trimester: dose changes are normal

Late in pregnancy, your body handles medicine differently. Blood volume expands and the liver breaks down buprenorphine faster. As a result, the same dose may not last as long, and you might notice cravings or withdrawal symptoms toward the end of the day.

That is a known, expected change, not a failure. Your prescriber may raise the dose or split it into smaller doses through the day. Many people return to their earlier dose in the weeks after birth, under their prescriber’s guidance. Speak up early if you feel symptoms rather than pushing through them.

Questions to bring to your next visit

Appointments can feel rushed, and it’s easy to forget what you meant to ask. Jot these down in your phone and check them off as you go:

• Should I stay on my current product, or is there a reason to switch?
• What should I do if I feel withdrawal or cravings late in the day?
• Which over-the-counter medicines for colds, heartburn, or sleep are okay with buprenorphine?
• Who do I call after hours if I lose a dose or run out?
• Does the hospital where I plan to deliver have experience caring for patients taking Suboxone during pregnancy?
• Will my insurance keep covering treatment after the baby is born?

Common worries about Suboxone while pregnant

Fear fills in gaps where facts are missing. These are the concerns people raise most often, with what is currently known.

Does buprenorphine cause birth defects?

Studies so far have not shown a clear pattern of major birth defects linked to buprenorphine. The 2024 JAMA analysis focused on newborn and maternal outcomes rather than malformations, and research continues. Ask your prenatal provider about the standard anatomy scan, which checks the baby’s development in the second trimester.

Will people judge me?

Some people still carry outdated ideas about medication for addiction. Clinicians who work in this area know that staying on Suboxone during pregnancy is responsible care, and many hospitals now train staff to respond without stigma. If you feel judged, you can ask for a social worker or patient advocate.

What if I slip and use?

A return to use does not end treatment. Tell your prescriber honestly so they can adjust your dose or support. Never use alone, keep naloxone nearby, and remember that fentanyl in the street supply makes any use more dangerous now than it was a decade ago.

Building your birth plan

A good birth plan for someone on buprenorphine looks a lot like anyone else’s, with a few added notes. Writing them down ahead of time helps when labor gets busy.

1. Keep taking your daily dose through labor and after delivery unless your team tells you otherwise. Stopping right at birth can lead to withdrawal and worse pain.
2. Tell the anesthesia team that you take buprenorphine. They are used to it and can plan accordingly.
3. Epidurals and spinals work well and are a good option for labor and cesarean birth.
4. Expect pain relief may need adjusting. Because buprenorphine holds tightly to opioid receptors, other opioids can work less well. Your team may use non-opioid medicines, nerve blocks, or carefully adjusted opioid doses.
5. Ask that no one gives you naltrexone or a mixed opioid like nalbuphine or butorphanol without checking, since these can trigger withdrawal in people on buprenorphine.
6. Bring your prescriber’s contact details so the hospital can confirm your dose.

Neonatal abstinence syndrome and Eat, Sleep, Console

Because buprenorphine crosses the placenta, some babies show withdrawal signs after birth. Doctors call this neonatal abstinence syndrome (NAS) or neonatal opioid withdrawal syndrome (NOWS). It is expected, it is treatable, and it does not mean you did anything wrong by staying in treatment.

Signs usually show up within the first few days and can include:

• Fussiness and a high-pitched cry
• Trouble sleeping between feeds
• Tremors or stiff muscles
• Poor feeding or weak sucking
• Sneezing, stuffy nose, or yawning
• Loose stools or vomiting

Studies have not found a clear link between the dose of buprenorphine you take and how severe your baby’s withdrawal will be. Lowering your dose to “protect” the baby is generally not recommended, since it raises your own risk of relapse.

How Eat, Sleep, Console works

Many hospitals now use a gentler approach called Eat, Sleep, Console. Instead of scoring dozens of symptoms and reaching for medicine quickly, staff focus on three questions: Can the baby eat well? Sleep at least an hour? Be calmed within about ten minutes?

You are the main treatment. Rooming in, skin-to-skin contact, swaddling, a quiet dim room, and feeding on demand all help. Babies cared for this way often need less morphine and go home sooner. If a baby still struggles, medicine is still used.

Suboxone and breastfeeding

For most people who are stable in treatment, breastfeeding is encouraged. Only small amounts of buprenorphine pass into breast milk, and even less is absorbed by a baby’s gut. Naloxone is poorly absorbed when swallowed as well.

Breastfeeding brings its own benefits for a baby with NOWS: closeness, comfort, and frequent feeds that settle the baby. It may also ease withdrawal signs.

Your care team may advise against breastfeeding if you are using other drugs, drinking heavily, or have HIV. Hepatitis C alone is generally not a reason to avoid breastfeeding, though feeding on cracked or bleeding nipples is usually paused until they heal. Ask your pediatrician about your specific situation.

Postpartum: the most important months to stay on track

The weeks and months after birth are a high-risk period for relapse and overdose. Sleep loss, hormonal shifts, pain, stress, and sometimes a feeling that “the reason to stay well” has arrived can all shake recovery loose. Some people also lose insurance coverage after the postpartum window ends.

These steps can help you through the first year:

• Keep taking your medicine. Postpartum is not a good time to taper. If your dose was raised in pregnancy, any decrease should be gradual and guided by your prescriber.
• Keep naloxone at home and show a partner or family member how to use it. Naloxone nasal spray is available over the counter.
• Schedule your follow-ups before you leave the hospital, including your next prescriber visit and refill date.
• Watch for postpartum depression and anxiety. They are common and treatable. Our pages on anxiety relief and why sleep matters offer self-care ideas alongside, not instead of, professional care.
• Avoid mixing buprenorphine with benzodiazepines, alcohol, or sleep aids. The ceiling effect that limits buprenorphine’s breathing risk does not protect you when these are combined. See Suboxone and Xanax.
• Get the dental care you may have put off during pregnancy.
• Talk about birth control and spacing your next pregnancy.

A child protective services referral can be a common fear. Policies differ by state, and being in prescribed treatment generally reflects well on you. A hospital social worker can explain how it works where you live and help with a plan of safe care.

Pregnant and not yet in treatment

If you are using opioids and just found out you are pregnant, you are not alone, and it is not too late. Starting buprenorphine or methadone at any point in pregnancy helps.

Many hospitals and prenatal clinics can start treatment quickly, sometimes the same day. Starting buprenorphine requires being in mild-to-moderate withdrawal first to avoid precipitated withdrawal, which your clinician will guide. If you have been using fentanyl, the timing can be trickier, and some clinicians will suggest starting in a hospital setting.

Frequently asked questions

Is Suboxone safe during pregnancy?

Suboxone is considered a reasonable treatment option during pregnancy for people with opioid use disorder. A large 2024 study in JAMA found that buprenorphine with naloxone had similar or better newborn outcomes compared with buprenorphine alone. Staying in treatment is generally safer than stopping.

Should I switch from Suboxone to Subutex if I get pregnant?

Not necessarily. Older practice favored buprenorphine-only products, but newer research suggests the combination is a reasonable choice too. Your prescriber will decide based on your stability, preferences, and coverage, so don’t switch on your own.

Will my baby go through withdrawal if I take Suboxone while pregnant?

Some babies do develop neonatal abstinence syndrome, but it is often milder with buprenorphine than with methadone. Many babies need only comfort care like rooming in and skin-to-skin contact. If medicine is needed, it is given safely in the hospital.

Can I lower my dose to protect my baby?

Lowering your dose has not been shown to reliably reduce newborn withdrawal, and it raises your risk of cravings and relapse. In fact, many people need a higher dose in the third trimester. Any dose change should come from your prescriber.

Can I breastfeed while taking Suboxone?

Yes, breastfeeding is generally encouraged for people who are stable on buprenorphine. Only small amounts pass into milk, and breastfeeding may comfort a baby with withdrawal signs. Your care team may advise otherwise if you are using other substances or have HIV.

Is methadone or Suboxone better during pregnancy?

Both are recommended by ACOG. Buprenorphine is linked to milder newborn withdrawal, while methadone can be a better fit for people who need more structure or did not do well on buprenorphine. The best choice is the one you can stick with.

Can I get an epidural if I take Suboxone?

Yes. Epidurals and spinal anesthesia work well for people on buprenorphine. Tell the anesthesia team about your medicine ahead of time so they can plan pain control after birth too.

Why do I feel withdrawal in my third trimester?

In late pregnancy your blood volume rises and your body clears buprenorphine faster, so your usual dose may wear off sooner. This is common and expected. Your prescriber may increase or split your dose.

The bottom line

Taking Suboxone during pregnancy is a recognized, evidence-based way to protect both you and your baby. The old rule of switching to buprenorphine-only is softening thanks to new data, and methadone remains a strong alternative. Expect dose changes late in pregnancy, plan your birth with the anesthesia team, and know that newborn withdrawal is treatable, often with your own arms.

Above all, keep your treatment going after the baby arrives. The postpartum year is when support matters most.

This article is for education and is not medical advice. Do not start, stop, or change any medicine without talking to your prescriber. Buprenorphine products are controlled substances and should be used only with a valid prescription, exactly as directed. If you suspect an overdose, call 911 right away and give naloxone if you have it. For free, confidential help 24/7, call the SAMHSA National Helpline at 1-800-662-4357.
