Depression during pregnancy or after birth is frightening, and it’s more common than many people realize. Now, a large review of real-world safety reports suggests that five specific medications may raise that risk. If you’re pregnant, planning, or recently gave birth, this could change what you discuss with your doctor.
Perinatal depression affects about 1 in 8 women during pregnancy or in the first year after delivery. It can drain energy, disrupt sleep, and make daily life feel overwhelming. For years, doctors have known that hormones, stress, and personal history play roles. But the role of common medicines has been harder to pin down outside of small studies.
This new analysis looked at millions of reports sent to the FDA between early 2004 and mid-2025. These reports come from patients, doctors, and drugmakers who suspect a medicine caused a problem. They don’t prove cause and effect, but they can reveal patterns that traditional studies might miss.
Here’s the twist: instead of relying on controlled trials, researchers used special statistical tools to spot “red flags” in this real-world data. They looked for drugs that showed up more often alongside perinatal depression than expected, then checked if those signals held up after accounting for age, weight, and other factors.
This doesn’t mean these medications cause depression in everyone.
The analysis flagged 28 drugs overall, but five stood out as independent risk factors: sodium oxybate (used for narcolepsy), levonorgestrel (a progestin-only contraceptive), ethinylestradiol/etonogestrel (a combined hormonal contraceptive), and lurasidone (an antipsychotic). Younger age (under 26) and higher weight (over 74 kg) also raised risk.
Think of the body’s mood system like a finely tuned orchestra. Some medicines may nudge the “volume knobs” in ways that make depression more likely during the vulnerable perinatal window. The report didn’t explain exactly how each drug does this, but the pattern was consistent across thousands of cases.
The researchers built a prediction model using these signals. It achieved a ROC-AUC of 0.907, a score that suggests the model is very good at telling who might be at higher risk. In plain terms: it separated higher-risk cases from lower-risk cases with high accuracy.
What does this mean for you? If you’re taking one of these medications and are pregnant or planning, don’t stop on your own. Instead, bring this up with your doctor or psychiatrist. Ask whether there are alternatives that fit your health needs and family plans. If you’ve felt down since starting a medication or during pregnancy, your symptoms are real and treatable.
But there’s a catch. These findings come from adverse event reports, which can be influenced by how often a drug is used or how likely people are to report problems. The study can’t prove that these drugs cause perinatal depression. It shows a strong link that deserves careful attention.
Experts in women’s mental health often weigh the risks of untreated illness against medication side effects. This research adds a new layer to that conversation. It may help clinicians pay closer attention to mood changes in younger patients or those with higher body weight who use these specific drugs.
Looking ahead, this work points to the need for prospective studies that follow pregnant women over time. That would help confirm cause and effect and clarify how big the risk really is. For now, the best step is open, personalized conversations with your care team about benefits, risks, and alternatives.
