Key Takeaways
- Zoloft (sertraline) is generally considered one of the safer antidepressants during pregnancy, with most studies showing women who take it are just as likely to have healthy babies as those who do not.
- Untreated depression during pregnancy carries its own risks, including preterm birth, low birth weight, difficulty bonding with the baby, and increased likelihood of postpartum depression.
- About 25–30% of babies exposed to SSRIs may experience mild, temporary neonatal adaptation syndrome symptoms after birth, which typically resolve within days to two weeks without treatment
- Sertraline is considered compatible with breastfeeding because it passes into breast milk at very low levels.
Zoloft is one of the most studied antidepressants in pregnancy — and the research is more reassuring than many women expect. Finding out you’re pregnant while taking Zoloft, or considering whether to start it, raises real questions. You want to protect your mental health and your baby. The good news is that for most women, these goals are not at odds with each other.
What is Zoloft?
Zoloft is the brand name for sertraline, a medication in a class called selective serotonin reuptake inhibitors (SSRIs). SSRIs work by increasing serotonin levels in the brain, which helps regulate mood and reduce symptoms of depression and anxiety.
Doctors prescribe Zoloft for major depressive disorder, generalized anxiety disorder, panic disorder, and obsessive-compulsive disorder. Because sertraline has been studied for decades, it remains one of the most commonly prescribed antidepressants for people who are pregnant or planning to become pregnant.
Is Zoloft safe during pregnancy?
Zoloft is generally considered one of the safer antidepressants to take during pregnancy. Most studies show that women who use sertraline while pregnant are just as likely to have healthy babies as women who do not take the medication. Many women continue Zoloft throughout pregnancy under medical guidance without complications.
That said, the decision to continue, adjust, or stop any medication during pregnancy involves weighing benefits against potential risks. Untreated depression carries its own concerns, including preterm birth, low birth weight, and difficulty bonding with your baby after delivery.
For many women, staying on Zoloft supports a healthier pregnancy overall.
- Favorable safety profile: Sertraline has more research supporting its use during pregnancy compared to many other antidepressants.
- Untreated depression poses risks too: Stopping medication can lead to worsening symptoms that affect both you and your pregnancy.
- Individual decision: What works for one person may not be right for another — your provider can help you find the right approach for your specific situation.
What is the pregnancy category for Zoloft?
The FDA no longer uses letter-based pregnancy categories. Zoloft’s current labeling reflects decades of research and indicates that sertraline does not appear to increase the risk of major birth defects. Third-trimester use may require closer monitoring, which your provider will guide you through. Overall, sertraline is one of the most studied and commonly prescribed antidepressants for pregnant women, and many take it safely throughout pregnancy.
Does Zoloft increase the risk of birth defects?
Most studies have not found a meaningfully higher chance of birth defects when sertraline is used during pregnancy. A large CDC-funded analysis examining over 17,000 pregnancies found no confirmed association between sertraline and birth defects — more reassuring than earlier, smaller studies suggested. The overall risk appears to be very low, and sertraline remains one of the most studied antidepressants available for pregnant women. If you have concerns, your provider can review the latest research with you.
Can taking Zoloft cause miscarriage?
Research has not established a clear link between sertraline and an increased risk of miscarriage, and studies examining this question have consistently found no meaningful increased risk. It is also worth noting that depression itself is associated with pregnancy complications — meaning that treating it, rather than avoiding medication, may actually support a healthier pregnancy overall.
How Zoloft can affect your baby during pregnancy
Studies show that women who take Zoloft during pregnancy are just as likely to have healthy babies as those who do not.
Preterm birth and low birth weight
Some studies have noted a small association between SSRI use and slightly earlier delivery or lower birth weight. Researchers believe this may reflect the impact of untreated depression rather than the medication itself — and when differences do appear, they tend to be modest.
Persistent pulmonary hypertension
Persistent pulmonary hypertension of the newborn (PPHN) is a rare breathing condition that can occur shortly after birth. Some research has suggested a small increased risk with SSRI use in the third trimester, though the overall occurrence remains very low.
Neonatal adaptation syndrome
Some babies born to mothers taking SSRIs experience a brief adjustment period after birth known as neonatal adaptation syndrome. Studies suggest this affects roughly 25–30% of exposed infants, with mild symptoms like fussiness or feeding difficulties that typically resolve within a few days to two weeks without treatment.
Can Zoloft cause newborn withdrawal symptoms?
While some parents worry about withdrawal, what newborns sometimes experience is actually quite different — a temporary adjustment period called neonatal adaptation syndrome. Unlike true withdrawal, these symptoms are mild and typically resolve on their own within a few days to two weeks.
Symptoms can include:
- Jitteriness or tremors: Mild shakiness that usually resolves quickly
- Irritability or fussiness: More crying than usual in the first few days
- Feeding difficulties: Some babies may be slower to feed initially
- Sleep disturbances: Changes in sleep patterns that typically normalize
Hospital staff are familiar with monitoring for these signs and can provide reassurance and support. In most cases, no treatment is needed, and symptoms resolve within days to a couple of weeks.
Does sertraline affect long-term child development?
Research on long-term child development following prenatal SSRI exposure is ongoing. Most studies have not found significant differences in IQ, behavior, or temperament in children followed up to 7 years old, and the largest studies to date have found no increased risk of neurodevelopmental disorders. Your provider can help you weigh the current evidence in the context of your specific situation.
Why treating depression during pregnancy matters
It is easy to focus on the potential risks of medication, but untreated depression also carries real risks for both you and your baby. Balancing both sides of this equation is an important part of making an informed decision.
Risks of untreated depression for the mother
Depression during pregnancy can affect your ability to take care of yourself and prepare for your baby’s arrival.
- Poor self-care: You may find it harder to attend prenatal appointments, eat well, or get enough rest.
- Increased stress hormones: Elevated cortisol levels from chronic stress can affect your body during pregnancy.
- Postpartum complications: Untreated prenatal depression significantly increases the risk of postpartum depression and postpartum anxiety.
Risks of untreated depression for the baby
When depression goes untreated, it can also affect pregnancy outcomes and early bonding.
- Preterm birth: Maternal depression is associated with earlier delivery, regardless of medication use.
- Low birth weight: Untreated mental health conditions have been linked to lower birth weights.
- Bonding difficulties: Depression can make it harder to connect with your baby after birth, which affects early attachment.
Alternatives to Zoloft for pregnant women
Some women prefer to explore non-medication options, either instead of or alongside antidepressant treatment. The right choice depends on your symptoms, history, and how you’ve responded to treatment before.
Therapy and counseling
Psychotherapy, particularly cognitive behavioral therapy (CBT) and interpersonal therapy, can be highly effective for treating depression without medication. For mild to moderate depression, therapy alone may be sufficient. For more severe symptoms, combining therapy with medication often provides the best results.
Transcranial magnetic stimulation
Transcranial magnetic stimulation (TMS) is a non-invasive, FDA-approved treatment for depression that does not involve medication. TMS uses magnetic pulses to stimulate areas of the brain involved in mood regulation. Some pregnant women choose TMS to avoid or reduce medication exposure. Ask your OB-GYN or psychiatrist whether TMS is available and appropriate for your situation.
Other antidepressant medications
If Zoloft is not the right fit for you, other SSRIs or antidepressants may be considered. Each medication has its own research profile during pregnancy, and your prescriber can help you compare options. The key is not to switch or stop medications on your own — always work with your provider to make changes safely.
Can you breastfeed while taking sertraline?
Sertraline is generally considered compatible with breastfeeding. While small amounts do pass into breast milk, the levels are typically very low, among the lowest of all antidepressants studied.
Most experts consider Zoloft to be a safer option for breastfeeding mothers who need antidepressant treatment. If you have questions about breastfeeding while on sertraline, your prescriber can give you guidance based on your specific situation and your baby’s needs.
How to talk to your doctor about Zoloft and pregnancy
If you are pregnant or planning to become pregnant and currently take Zoloft, having an open conversation with your provider is an important first step. Here is how to approach it:
- Don’t stop suddenly: Stopping Zoloft abruptly can cause withdrawal symptoms and increase the risk of your depression returning. Always talk to your provider before making changes.
- Share your concerns: Let your doctor know what worries you, whether it is potential effects on your baby, your own mental health, or something else entirely.
- Discuss your history: Help your provider understand how severe your depression has been, what treatments have worked, and what happens when you are not on medication.
- Ask about the lowest effective dose: Many providers aim to use the smallest dose that keeps symptoms well-controlled during pregnancy.
- Create a monitoring plan: Work together to decide how your pregnancy and mental health will be monitored throughout.

FAQs about taking Zoloft while pregnant
What should I do if I find out I’m pregnant while taking Zoloft?
Do not stop taking Zoloft suddenly. Contact your prescriber right away to discuss your options. Together, you can create a plan that considers both your mental health needs and your pregnancy.
Can my doctor prescribe a lower dose of Zoloft during pregnancy?
Your provider may recommend adjusting to the lowest effective dose, which balances keeping your symptoms well-controlled with minimizing fetal exposure. This is a common approach during pregnancy.
Does a father’s use of Zoloft affect pregnancy or the baby?
Current research has not found that paternal sertraline use increases the risk of birth defects or pregnancy complications. If you have questions about a partner’s medication use, discussing them with a healthcare provider can provide additional reassurance.
How far in advance should I talk to my doctor if I’m planning to become pregnant while on Zoloft?
Ideally, discuss your medication plan with your prescriber before trying to conceive. This gives you time to make informed decisions together about whether to continue, adjust, or explore alternatives to your current treatment.
