Psychiatric Medication During Pregnancy: What You Actually Need to Know
Written by Vaishali Desai, PMHNP-BC, DNP
If you're pregnant — or planning to become pregnant — and you're on psychiatric medication, you have almost certainly been told to “be careful” or been handed conflicting information that left you more anxious than when you started. The internet is full of horror stories. Your prescriber might not have had time to give you a real answer. And the stakes feel impossibly high.
This guide is written to give you the clinical context that most people in this situation never receive — including the context that staying on medication during pregnancy is often the safer choice, and that abruptly stopping is one of the most common — and most dangerous — decisions I see patients make.
Why This Decision Is So Hard
The framing most people bring to this decision — medication versus no medication — is a false binary. It implies that one side of the equation carries risk and the other doesn't. That's not how this works clinically. Untreated mental illness during pregnancy carries its own documented risks to fetal development and maternal health.
The research is clear: chronic stress and elevated cortisol from untreated anxiety and depression are associated with preterm birth, low birth weight, impaired fetal neurodevelopment, and poor prenatal care (skipped appointments, inadequate nutrition, sleep deprivation). Untreated bipolar disorder and OCD carry similar risks — mood episodes, intrusive thoughts, and the behavioral consequences of both can disrupt pregnancy in significant ways. Postpartum relapse rates after stopping medication during pregnancy are among the highest in psychiatry.
The real clinical question is not “medication or no medication” — it's which risk is greater for this specific patient? That question has a different answer for everyone, and it requires a real conversation — not a reflexive stop order.
From the clinic: “I work through this decision with patients every week. There is no universal answer — but staying on medication during pregnancy is often the safer choice, and that's not said enough.” — Vaishali Desai, PMHNP-BC, DNP
What the Research Actually Says
The evidence base on psychiatric medications in pregnancy is large, nuanced, and constantly evolving. Here is where things stand by medication class.
SSRIs — The Most Studied Class
Selective serotonin reuptake inhibitors — particularly sertraline (Zoloft) and fluoxetine (Prozac) — have more pregnancy safety data than almost any other class of psychiatric medication. They are generally considered lower risk and are among the most commonly continued medications through pregnancy. Sertraline is often the first choice for patients who need to start or switch during pregnancy because of the volume of data behind it.
SNRIs
Serotonin-norepinephrine reuptake inhibitors (venlafaxine, duloxetine) have a reasonable body of data — not as large as SSRIs, but comparable in risk profile. For patients already stable on an SNRI, discontinuing to switch to an SSRI is not automatically the right move. Destabilization during a switch carries its own risks.
Benzodiazepines
Benzodiazepines (Xanax, Klonopin, Ativan, Valium) carry more concern in pregnancy and are typically tapered if possible, particularly in the first trimester. However, abrupt discontinuation of a benzo someone has been taking regularly is dangerous in its own right — seizure risk is real. Tapering slowly, under supervision, is the standard of care.
Mood Stabilizers — Significant Variation
This class requires individualized decision-making more than any other:
- Valproate (Depakote) carries the highest documented risk — associated with neural tube defects and neurodevelopmental effects. It is generally avoided in pregnancy when alternatives exist.
- Lithium requires careful monitoring — it has a narrow therapeutic window, and pregnancy changes how the body handles it. Dose adjustments and more frequent blood draws are standard. But for someone with bipolar I disorder who has relapsed when lithium was stopped, the risk calculus often strongly favors continuing.
- Lamotrigine (Lamictal) is among the better-studied options and is often continued — with close monitoring, as lamotrigine clearance increases significantly during pregnancy and doses frequently need to be adjusted upward.
Stimulants (ADHD)
Stimulant medications are typically paused during pregnancy and reassessed postpartum. The data on stimulant safety in pregnancy is more limited, and for many patients with ADHD, a brief pause is manageable — particularly with behavioral supports in place. This is an individualized conversation depending on how significantly ADHD is impairing function.
Neonatal Adaptation Syndrome
Some babies born to mothers taking SSRIs or SNRIs late in pregnancy show signs of neonatal adaptation syndrome — jitteriness, irritability, feeding difficulties, mild respiratory changes — in the days following birth. This is temporary, typically resolves within 1–2 weeks without treatment, and does not indicate lasting harm. It is monitored by neonatal care teams and is not, by itself, a reason to stop medication before delivery.
From the clinic: “The FDA risk categories were retired — current guidance is nuanced and individualized. What worked for your sister or your friend doesn't dictate what's right for you.” — Vaishali Desai, PMHNP-BC, DNP
The Risk of Stopping Abruptly
One of the most common mistakes I see: a patient finds out they're pregnant, panics, and stops their medication immediately — without calling their prescriber, without a taper plan, sometimes without telling anyone.
Discontinuation Syndrome
Stopping SSRIs or SNRIs suddenly causes discontinuation syndrome — a collection of physical and psychological symptoms including dizziness, electric shock sensations (“brain zaps”), nausea, irritability, profound anxiety, and flu-like feelings. These symptoms can be severe. They are not a sign of addiction — they are the nervous system adjusting to the absence of a medication it had adapted to. Tapering slowly, when discontinuation is appropriate, avoids most of this.
Relapse Risk
The relapse risk for depression and anxiety after stopping medication during pregnancy is high — particularly in the first trimester, when many people discover they are pregnant and make sudden changes. Untreated depression and anxiety in pregnancy are associated with preterm birth, low birth weight, poor bonding after delivery, and significantly elevated postpartum crisis rates. The fetus is not protected by a mother stopping her medication — it may be exposed to more harm from the untreated illness.
The “I'll Just Push Through It” Trap
Many patients tell themselves they can manage the next nine months without help — that they'll white-knuckle through the anxiety or depression for the sake of the baby. This is a category error. It assumes that suffering stoically is neutral for the fetus. It isn't. Chronic stress hormones, poor sleep, difficulty eating, social withdrawal, and impaired prenatal care are not neutral inputs into a pregnancy. The “push through it” choice has real consequences, and pretending otherwise doesn't protect anyone.
From the clinic: “Stopping cold turkey because you found out you're pregnant is one of the most common mistakes I see. Please call your prescriber before making any changes.” — Vaishali Desai, PMHNP-BC, DNP

How to Have the Conversation With Your Prescriber
The best time to have this conversation is before you are pregnant. Preconception planning — ideally 3–6 months before you start trying — gives your prescriber time to optimize your regimen: switch to medications with more pregnancy safety data, reach the lowest effective dose, and document your baseline so that any changes during pregnancy can be evaluated against it.
If you're already pregnant, the conversation still needs to happen — as soon as possible, and before making any medication changes on your own.
What to Bring to the Appointment
- A list of your current medications with doses and how long you've been on each
- Your full diagnosis history — including conditions that are well-controlled and might not have come up recently
- Any previous medication trials, including what worked and what didn't
- Questions written down — it's easy to forget in the moment
Questions to Ask
- Is my current medication the safest option for pregnancy?
- What monitoring will I need if I stay on this medication?
- Who should be on my care team — OB, psychiatrist, midwife? Do they need to coordinate with each other?
- What are the signs of relapse I should watch for, and when should I call you?

From the clinic: “If your prescriber dismisses your mental health concerns during pregnancy without a real conversation, that's a red flag. You deserve a collaborative discussion.” — Vaishali Desai, PMHNP-BC, DNP
Postpartum: A Different Risk Calculus
Surviving pregnancy with your mental health intact does not mean the risk is over. The postpartum period is actually a period of higher psychiatric relapse risk than pregnancy itself — the hormonal drop after delivery is rapid and dramatic, sleep deprivation is severe, and the psychological demands of new parenthood are real.
Postpartum depression affects approximately 1 in 5 people who give birth. For those with a psychiatric history, the rates are substantially higher. Medication decisions that made sense during pregnancy may need to shift again after delivery — and the calculus is different.
Breastfeeding and Medication
The concern about breastfeeding is real but frequently overstated. Most SSRIs — particularly sertraline — have low transfer to breast milk. Infant exposure is minimal, and for most medications in this class, continuing medication and breastfeeding is entirely reasonable. The risk of untreated postpartum depression to infant development (impaired bonding, inconsistent caregiving, developmental delays) generally outweighs the risk of low-level medication exposure through breast milk. This is not automatically a reason to stop.
Postpartum Psychosis
For patients on mood stabilizers who stopped during pregnancy, immediate postpartum restart is often medically urgent. Postpartum psychosis is a psychiatric emergency — hallucinations, delusions, rapid mood cycling, severe confusion — and it is strongly associated with bipolar disorder history and with stopping mood stabilizers. The postpartum period is the highest- risk window for postpartum psychosis. If you stopped a mood stabilizer during pregnancy, your plan for postpartum should include an explicit timeline for restarting.

Questions to Ask Your Prescriber
These five questions are specific enough to open a productive clinical conversation — even in a short appointment — and to make sure the most important issues are on the table:
- “Is my current medication the best choice if I'm pregnant or planning to become pregnant?” — Opens the door to a regimen review before pregnancy, when there's still time to optimize. Don't wait until you're already pregnant to ask this.
- “What are the documented risks of continuing this medication versus stopping it?” — Forces a both-sides risk assessment. “The medication carries some risk” is only half the answer. “Untreated depression also carries these specific risks” is the other half.
- “Should I see a perinatal psychiatrist in addition to my regular prescriber?” — Perinatal psychiatry is a subspecialty. For complex presentations — bipolar disorder, OCD, high-dose regimens — a specialist consult can be invaluable and is often available via telehealth.
- “What signs should I watch for in my newborn if I stay on medication through delivery?” — Neonatal adaptation syndrome is manageable and temporary, but you should know what to expect and what to tell your neonatal care team.
- “What's the plan for my medications after I give birth, especially if I want to breastfeed?” — The postpartum medication plan should be made before delivery — not on the fly in the days after. Ask for a written plan.
