- Whether to use trazodone in pregnancy is an individual decision best made with your OB and the prescriber who manages your care, not something to start or stop on your own.
- MotherToBaby reports that studies of more than 300 first-trimester exposures did not find an increased chance of birth defects above the background risk, though the overall data are more limited than for some other antidepressants.
- Several studies did not find a higher chance of miscarriage, and one study found no increase in preterm delivery or low birth weight, though findings across studies are mixed.
- Untreated depression, anxiety, or insomnia can carry their own risks in pregnancy, so the goal is effective, safe treatment rather than simply stopping medication.
- Some newborns may show temporary adjustment symptoms after birth, and stopping an antidepressant suddenly can cause discontinuation symptoms or relapse.
- The old FDA A/B/C/D/X pregnancy letter categories have been retired; today's labeling is narrative, and questions can go to MotherToBaby at 1-866-626-6847.
Trazodone is used both for depression and, very commonly, as a sleep aid, so a lot of people find themselves taking it and then wondering what it means for pregnancy. If that is you, this article gathers what leading U.S. sources say about trazodone in pregnancy so you can have a clearer conversation with the clinicians who manage your care. It is general education only and is not a substitute for that conversation.
What trazodone is and what it treats
Trazodone is an antidepressant that affects serotonin signaling in the brain, but it is chemically different from the SSRIs and is not a benzodiazepine or a “sleeping pill” in the usual sense. At higher doses it is used to treat depression; at lower doses it is very widely prescribed off-label to help with sleep, because it tends to be sedating. Understanding why you take it, for mood, for sleep, or both, is part of what makes any pregnancy decision individualized.
What the guidance says about pregnancy
MotherToBaby, a service of the non-profit Organization of Teratology Information Specialists, reports that studies examining more than 300 pregnancies with first-trimester trazodone exposure did not find an increased chance of birth defects above the background risk that exists in every pregnancy. That is reassuring as far as it goes, but it is worth being honest that the total amount of data on trazodone in pregnancy is more limited than for some of the more heavily studied antidepressants, such as certain SSRIs. Where the evidence is thinner, clinicians tend to individualize more carefully rather than less.
Specific concerns that have been studied
MotherToBaby describes several areas researchers have examined, and the findings are mixed rather than uniform.
Miscarriage. Multiple studies did not find an increased chance of miscarriage with trazodone. MotherToBaby notes that one study suggested a higher miscarriage rate with antidepressants overall, but only a small share of those exposures, around two percent, involved trazodone specifically, which limits what can be concluded about the drug itself.
Preterm birth and growth. MotherToBaby reports that one study found no increased chance of preterm delivery or low birth weight, while another suggested a slightly higher chance of preterm delivery, and a third raised the possibility of increased preeclampsia and small-for-gestational-age birth. Importantly, those signals were not specific to trazodone alone, and untreated depression itself is also associated with pregnancy complications, which makes cause and effect hard to untangle.
Newborn adjustment symptoms. MotherToBaby notes that temporary newborn symptoms such as jitteriness, breathing difficulties, or feeding problems can occur with antidepressants used late in pregnancy, though these were not observed in one small study of infants exposed to a low daily dose.
Longer-term development. MotherToBaby is candid that studies have not been done on trazodone’s effects on a child’s later behavior and learning, so this remains an open question.
The other side: untreated illness carries risks too
It is easy to focus only on the medicine, but the reason you take it matters just as much. Untreated or undertreated depression in pregnancy is not risk-free; it can be associated with poor engagement in prenatal care, inadequate nutrition and self-care, and, in serious cases, thoughts of self-harm. Poor sleep and untreated anxiety can also take a real toll. The goal your care team will aim for is effective, appropriate treatment, not simply stopping medication. For some people the safest plan is to continue trazodone; for others, a different approach for mood or sleep may make sense. That balance is personal.
Do not start or stop on your own
This is the most important practical point. Do not stop trazodone abruptly on your own. Antidepressants can cause discontinuation symptoms when stopped suddenly, and stopping can allow the underlying depression, anxiety, or insomnia to return. If you are worried, the right move is to contact your prescriber and your OB and plan any change together. Likewise, do not start trazodone, or switch to it for sleep, during pregnancy without that same guidance. Because trazodone is often used off-label for sleep, it is especially worth asking your clinician whether it is still the best choice for you now, rather than assuming the answer either way.
A note on the old letter categories
You may have seen older references to FDA pregnancy “categories” such as A, B, C, D, and X. That system has been retired. U.S. drug labels now use a narrative format under the Pregnancy and Lactation Labeling Rule, which describes what is actually known rather than assigning a single letter. If you come across an old letter grade for trazodone, treat it as out of date and ask your clinician for the current picture.
Breastfeeding
MotherToBaby reports that trazodone passes into breast milk in small amounts and that the information available is limited. It advises contacting a healthcare provider if a nursing baby shows unusual symptoms, such as excessive sleepiness. As always, confirm the plan with your baby’s clinician, especially for a premature or medically fragile infant.
When to call your OB or a specialist
Reach out to your obstetric provider and your prescriber if you are pregnant or planning pregnancy and take trazodone, if you are thinking about stopping or changing it, or if your mood, anxiety, or sleep worsens. If your situation is complex, your team may involve a maternal-fetal-medicine specialist or a perinatal psychiatrist. For questions about a specific exposure, you can call MotherToBaby at 1-866-626-6847, a free service that answers questions about medicines in pregnancy and breastfeeding. If you ever have thoughts of harming yourself, call or text 988, the Suicide and Crisis Lifeline, right away.
Frequently asked questions
Is trazodone safe to take while pregnant? “Safe” is individual. MotherToBaby reports that studies of more than 300 first-trimester exposures did not find an increased chance of birth defects, while noting the data are more limited than for some other antidepressants. Decide with your OB and prescriber.
I took trazodone before I knew I was pregnant. Should I worry? Try not to panic. MotherToBaby reports no increased chance of birth defects above background risk in the studies available. Tell your OB what you took and when, and ask questions there or through MotherToBaby.
I only take it for sleep. Is that different? The exposure is similar regardless of why it is prescribed, but the decision may differ. Since trazodone is used off-label for sleep, ask your clinician whether it is still the best option for you during pregnancy.
Will my baby have symptoms after birth? Some babies exposed to antidepressants late in pregnancy show temporary symptoms such as jitteriness or feeding trouble. MotherToBaby notes these were not seen in one small low-dose study. Your care team can watch for them.
Can I breastfeed while taking it? MotherToBaby reports small amounts pass into breast milk and that information is limited, advising you to watch for unusual sleepiness. Confirm with your baby’s clinician, especially for a newborn or fragile infant.
What if I feel fine and want to stop? Talk to your prescriber first. Stopping abruptly can cause discontinuation symptoms and allow the original problem to return, so any change should be planned rather than sudden.
This article is general education, not medical advice, and must not be used to start, stop, adjust, or taper any medication on your own. Suddenly stopping some medicines can be dangerous. Always work with the prescriber who manages your care. In an emergency call 911; for mental-health crisis call or text 988.
