Ativan During Pregnancy & Breastfeeding: The Evidence

Few medication questions carry as much emotion as this one. If you take Ativan (lorazepam), and you are pregnant, planning a pregnancy or nursing a newborn, you are probably caught between two worries: the possible effect of the medicine on your baby, and the very real effects of untreated anxiety, panic or insomnia on you. Searching online tends to produce either alarming headlines or breezy reassurance, and neither helps.

This article lays out what the evidence says, in plain language and with its uncertainties intact. It is not a substitute for individual advice, and it will not tell you what to do, because the right choice depends on why you take Ativan, how much and how often, and what alternatives suit you. What it can do is help you walk into that conversation informed. One rule comes first and is repeated below: if you take Ativan regularly, do not stop it suddenly on your own, whether or not you are pregnant. Abrupt withdrawal can cause serious problems, including seizures. For general background, see Ativan uses.

What to know in 60 seconds

Pregnancy: Ativan is not considered the first choice, and it is generally used only when the benefit clearly outweighs the risk and non-drug options are not enough. Large reviews have found little or no clear increase in major birth defects, but some studies link benzodiazepines to a higher risk of miscarriage, and results are mixed and hard to separate from the effects of the underlying condition.
Late pregnancy and delivery: Newborns exposed near delivery can show sedation, floppiness, breathing and feeding difficulties, or withdrawal signs. Their care team needs to know.
Breastfeeding: Lorazepam passes into breast milk in small amounts. Many references consider occasional, low use acceptable with monitoring of the baby for sleepiness and poor feeding, while the drug label advises caution.
Do not stop suddenly if you take it regularly; make a plan with your prescriber.
Effective alternatives exist, including therapy and certain antidepressants.

Why this question is hard to answer

Medicines are rarely tested in pregnant people before approval, for good ethical reasons. What we know about benzodiazepines in pregnancy therefore comes from observational studies: researchers compare outcomes in people who took the medicine with outcomes in those who did not. These studies are valuable but have limitations that matter here.

Confounding by indication. People who take Ativan usually have anxiety, panic, insomnia or another condition. Those conditions, and their effects on sleep, nutrition, smoking, alcohol use and stress hormones, may influence pregnancy outcomes independently of the drug.
Other exposures. Many people who take benzodiazepines also take other medicines, drink alcohol or smoke. Better studies adjust for these factors, but not perfectly.
Different drugs, different doses and timing. “Benzodiazepines” include many drugs with different properties, and the timing of exposure (early, late, throughout) changes what risks are relevant. Studies of other benzodiazepines do not automatically apply to lorazepam.
Rare outcomes need large numbers. Birth defects are uncommon, so small studies may miss a modest increase or flag one that is just chance.

For this reason, expert groups usually describe the evidence in terms of “possible” or “small” risks rather than certainties.

Understanding the baseline

Every pregnancy has a background chance of complications, unrelated to any medicine. In the general U.S. population, major birth defects occur in roughly 2 to 4 percent of pregnancies, and miscarriage occurs in roughly 15 to 20 percent of clinically recognized pregnancies. When you read about “increased risk,” keep these baselines in mind. A relative increase on a small base is still a small absolute change, although it matters when it is avoidable.

Ativan and pregnancy: what the evidence suggests

The first trimester and birth defects

Early reports in the 1970s linked some tranquilizers to oral clefts and other malformations, which led to widespread caution. Larger and better-controlled studies since then, including meta-analyses and population-based cohorts, have generally found little or no clear association between benzodiazepine use and major congenital malformations, particularly after adjusting for other exposures. The current Ativan prescribing information notes that more recent case-control and cohort studies, adjusted for confounders such as alcohol, tobacco and other medicines, have not confirmed the earlier concerns.

That said, uncertainty remains. A small number of studies have raised specific hypotheses, such as a possible link between lorazepam exposure and a rare bowel malformation called anal atresia. These were described as hypothesis-generating and have not been consistently replicated. Because individual drugs differ and dose may matter, experts generally advise minimizing exposure in the first trimester when it is safe to do so, rather than assuming there is no risk.

Miscarriage

Several studies have found an association between benzodiazepine use early in pregnancy and a higher risk of miscarriage, including a large 2024 analysis published in JAMA Psychiatry. Researchers caution that this association may reflect, at least in part, the effects of the underlying conditions, or other factors, and that these studies cannot prove the medicine causes pregnancy loss. Even so, the finding is one reason clinicians are careful about starting a benzodiazepine in early pregnancy without a clear need.

Late pregnancy, labor and the newborn

The best-established concerns involve use near the time of delivery. Benzodiazepines cross the placenta, and a baby exposed late in pregnancy or during labor can be born with:

Sedation or poor muscle tone (sometimes called “floppy infant syndrome”)
Breathing difficulties or low oxygen at birth
Feeding problems and poor sucking
Low body temperature
Withdrawal symptoms in the days or weeks after birth, such as irritability, tremor, restlessness, high-pitched crying or sleep and feeding disturbances (neonatal withdrawal syndrome)

The prescribing information advises monitoring neonates exposed to Ativan during pregnancy or labor for sedation, breathing depression, low muscle tone and feeding problems, and monitoring those exposed to the tablets during pregnancy for withdrawal. For this reason, tell your obstetric team and your baby’s pediatric team if you have taken lorazepam regularly in late pregnancy so they can prepare.

Longer-term development

Studies on neurodevelopment of children exposed to benzodiazepines in the womb have produced mixed results. Some find no clear difference after accounting for maternal factors; others suggest subtle effects on behavior or attention that are difficult to separate from the underlying maternal condition. The overall picture does not point to a large, consistent harm, but it is not a reason to dismiss the question.

Other considerations

Preterm birth and low birth weight: Some studies report small associations, which again may be confounded.
Combination with other medicines: Using benzodiazepines together with opioids or alcohol raises risks for both the pregnant person and the baby.
Maternal safety: Sedation, falls, and breathing risks apply in pregnancy just as at any other time.

The other side of the scale: untreated anxiety matters too

It is tempting to think that stopping medication is automatically the safest option. In reality, severe untreated anxiety, panic or insomnia during pregnancy is associated with its own risks, including poor sleep and nutrition, higher blood pressure in some cases, difficulty attending appointments, a greater chance of postpartum depression and, in some studies, adverse birth outcomes. Anxiety and depression in pregnancy are common and treatable, and doctors increasingly emphasize treating them rather than hoping they pass.

This is why the question is rarely “medicine versus no medicine” but “which approach gives the best overall outcome for you and your baby.” Often the answer combines non-drug treatment with a carefully chosen medicine at the lowest effective amount for the shortest necessary time.

Options doctors commonly consider

1. Non-drug treatments (first-line for many)

Cognitive behavioral therapy (CBT): Has strong evidence for anxiety and panic and is safe in pregnancy.
Cognitive behavioral therapy for insomnia (CBT-I): Effective for sleep problems without medication; see can CBT-I replace sleeping pills.
Mindfulness-based programs, relaxation training, breathing techniques and exercise (as cleared by your obstetric provider).
Support groups and perinatal mental health services.

2. Medicines with more pregnancy data for long-term anxiety

For ongoing anxiety or depression, doctors often consider SSRIs such as sertraline, which have more reassuring data and are not habit-forming, although they too carry considerations (for example, a possible temporary adjustment syndrome in newborns). Other options may be chosen case by case. These decisions should be made with a prescriber experienced in perinatal mental health.

3. Planned, minimal benzodiazepine use

If a benzodiazepine is judged necessary, for instance for severe, disabling panic, certain medical conditions or while a long-term treatment takes effect, prescribers typically aim for the lowest effective amount for the shortest time, avoid combining it with other sedatives, and plan for delivery. Lorazepam is sometimes favored in this situation because of its relatively short half-life and the way the body processes it, although “favored” does not mean risk-free.

4. Gradual tapering when appropriate

If you take Ativan regularly and are planning pregnancy or have just discovered you are pregnant, a slow, supervised taper may be recommended, depending on your situation. Do not stop abruptly. Sudden discontinuation can cause rebound anxiety, severe insomnia and seizures, which are dangerous for you and the pregnancy.

If you are planning a pregnancy

The best time to review your medicines is before conception. A preconception visit with your prescriber can help you:

Clarify whether you still need Ativan and what it is treating
Start or strengthen therapy and non-drug strategies
Switch to a medicine with a better pregnancy track record if needed
Taper gradually, if appropriate, rather than rushing
Review alcohol, caffeine and other medicines

If you find out you are pregnant while taking Ativan

This is extremely common, since many pregnancies are unplanned. Try to stay calm, because panic is not helpful and a short period of exposure early on does not in itself mean something has gone wrong.

Contact your prescriber or obstetric provider promptly, ideally the same week.
Continue as directed until you have a plan if you take it regularly. Do not stop suddenly.
Do not take extra tablets to cope with the stress of the news.
Ask for a risk discussion tailored to your dose, timing and condition.
Consider contacting a teratology information service such as MotherToBaby (in the United States, 1-866-626-6847) for free, confidential information.

Labor, delivery and the newborn period

Tell the birth team that you take lorazepam, including how often and when you last took it.
The pediatric team may observe your baby for sedation, breathing and feeding for a period after birth.
If you took lorazepam regularly near the end of pregnancy, ask what withdrawal signs to look for in the first weeks and whom to call.
Do not take extra doses to manage labor anxiety unless your care team directs it; ask about non-drug supports and anesthesia options.

Ativan and breastfeeding

How much gets into breast milk?

Lorazepam does pass into breast milk, but in relatively small amounts. Small studies and reports have not generally found sedation in breastfed infants of mothers taking it. A database maintained by the U.S. National Institutes of Health (LactMed) describes lorazepam as possible to use during breastfeeding, with the recommendation to monitor the infant for sedation, poor feeding and poor weight gain. A telephone follow-up study of mothers taking benzodiazepines while nursing found that none of those taking lorazepam reported sedation in their infants. Other professional bodies, such as the Academy of Breastfeeding Medicine, similarly indicate that breastfeeding is generally compatible with short-acting benzodiazepines used for anxiety when care is taken.

At the same time, the Ativan product label takes a more cautious stance: it says that the drug has been detected in breast milk, that sedation and inability to suckle have been reported in infants of mothers taking benzodiazepines, and that nursing mothers should avoid it unless the expected benefit to the mother outweighs the potential risk to the infant. These positions are not contradictory so much as reflecting different purposes: the label is a legal and conservative document, while lactation references weigh the available human data.

Who is at higher risk?

Newborns and premature infants, whose livers clear drugs more slowly
Babies with breathing problems, jaundice or poor feeding
Infants whose mothers take higher amounts, take it daily, or combine it with other sedatives or alcohol
Co-sleeping situations when the parent is sedated, which raises safety concerns for the baby

Practical steps if you breastfeed while taking Ativan

Use the lowest effective amount for the shortest time, as directed by your prescriber.
Avoid alcohol and other sedatives. Combined sedation in the parent is a major safety risk.
Watch your baby for unusual sleepiness, limpness, difficulty waking for feeds, poor sucking, poor weight gain, breathing pauses or irritability.
Consider timing. Some clinicians suggest taking a dose right after a feed or before the baby’s longest sleep stretch, although this is a general approach and not a guarantee. Ask your prescriber what works for you.
Do not drive or care for the baby alone while drowsy. Arrange help for nighttime feeds if you feel sedated, and never fall asleep with your baby on a sofa or armchair.
Tell your baby’s pediatrician that you take it.
Ask about alternatives. Therapy and certain antidepressants have a larger body of experience in breastfeeding.
Do not stop abruptly if you have been taking it regularly.

When to contact your baby’s doctor

Unusual drowsiness or difficulty waking for feeds
Poor feeding, weak suck or poor weight gain
Floppiness or reduced muscle tone
Slow or irregular breathing, or pauses in breathing
Persistent irritability or high-pitched crying (if exposed in late pregnancy)

Call emergency services if your baby is hard to rouse, has blue lips or is not breathing normally.

Postpartum anxiety and sleep: a risky time to rely on sedatives

The weeks after birth bring sleep deprivation, hormonal shifts and the stress of caring for a newborn. Anxiety, panic and insomnia are common and may be treated with sedatives, but sedation in a parent who is the sole night-time caregiver can be hazardous. If you struggle with anxiety or low mood after the baby arrives, reach out early. Perinatal mental health support is widely available, and in the United States, Postpartum Support International runs a helpline at 1-800-944-4773, and the 988 Suicide & Crisis Lifeline is available by call or text. Outside the U.S., ask your doctor or local health service about equivalents.

Questions to bring to your appointment

Why am I taking Ativan, and is it still the best option for me?
How often and how much do I take, and could that be reduced or stopped safely?
If I am pregnant or planning to be, what is the plan for the first trimester, late pregnancy and delivery?
What non-drug treatments could I start now?
Would a different medicine be safer during pregnancy or breastfeeding?
If I breastfeed, how should I time doses and what should I watch for in my baby?
Whom should I call if I have questions or my symptoms worsen?
Can I register in a pregnancy exposure registry or speak to a teratology service?

In the United States, the National Pregnancy Registry for Psychiatric Medications (1-866-961-2388) enrolls people taking psychiatric medicines during pregnancy to help build the evidence base, and your clinician can refer you.

Frequently asked questions

Is Ativan safe during pregnancy?

It is not considered a first choice, and there is no way to call any exposure “completely safe.” Large reviews have not shown a clear rise in major birth defects, but there are concerns about miscarriage associations, and newborn sedation or withdrawal when used late in pregnancy. Decisions should be individualized with your prescriber.

Can Ativan cause birth defects?

Older studies raised concern, but more recent, better-controlled research has generally not confirmed a strong link. A few isolated findings remain unconfirmed. Using the lowest effective amount, especially in the first trimester, is a common approach.

Should I stop Ativan if I find out I am pregnant?

Not on your own if you take it regularly. Abrupt discontinuation can cause withdrawal and seizures. Contact your prescriber promptly to make a plan.

Can I take Ativan occasionally in pregnancy?

Occasional, low use poses a different risk profile than daily use, but it should still be discussed with your prescriber, especially near delivery.

Is Ativan safe while breastfeeding?

Many lactation references consider occasional use acceptable with monitoring of the infant for sleepiness and feeding problems, while the drug label advises avoiding it unless the benefit outweighs the risk. Discuss your situation and your baby’s age and health with your clinicians.

How long should I wait to breastfeed after taking Ativan?

There is no single established waiting time. Some clinicians suggest dosing right after a feed or before the baby’s longest sleep, but the safest approach is to follow individualized advice and watch your baby for sedation.

What are the signs of benzodiazepine withdrawal in a newborn?

Irritability, tremor, restlessness, high-pitched crying, poor feeding and sleep problems, sometimes appearing days after birth. Tell the pediatric team about any regular lorazepam use late in pregnancy.

What can I use instead of Ativan for anxiety during pregnancy?

Cognitive behavioral therapy, relaxation techniques, exercise, sleep support and, where appropriate, antidepressants such as sertraline are common options. See how to calm an anxiety attack for practical coping tools.

Key takeaways

The evidence on Ativan in pregnancy is mixed: little clear increase in major birth defects in large reviews, a possible miscarriage association, and well-established concerns about newborn sedation and withdrawal with late use.
Untreated anxiety and insomnia carry risks too, so the goal is the best overall plan, not simply avoiding medicine.
Do not stop Ativan suddenly if you take it regularly; plan a gradual taper with your prescriber.
Breastfeeding while on lorazepam is often considered possible with monitoring, but the label urges caution; watch your baby for sleepiness and feeding problems.
Therapy and certain antidepressants are effective alternatives, and confidential support services exist for pregnancy and postpartum mental health.
