Key Takeaway
Note the increased risk of gestational diabetes associated with second-generation antipsychotics and antidepressants.

The researchers conducted a meta-analysis to evaluate the risk of gestational diabetes mellitus among pregnant women exposed to various psychotropic medications. The study specifically looked at the impact of both antidepressants and antipsychotics, including first-generation and second-generation varieties, on the development of gestational diabetes.

The analysis revealed that prenatal exposure to both antidepressants and second-generation antipsychotics was associated with an increased risk of gestational diabetes. In contrast, the data did not show a statistically significant association between first-generation antipsychotics and the development of the condition. These findings suggest that specific classes of psychotropic medications may have different impacts on maternal metabolic health.

Because the underlying data were sourced from observational studies, a direct causal link between medication use and gestational diabetes cannot be established. Clinicians should consider these findings when managing patients with psychiatric conditions during pregnancy. While the association is noted, individual patient risk profiles and the necessity of psychiatric treatment must remain primary considerations in clinical decision-making.

Managing mental health during pregnancy is a vital part of prenatal care. However, a new review of existing data suggests that some common medications might have unexpected effects on a mother's health. Specifically, the study looked at how taking certain medications for conditions like depression and anxiety impacts the risk of gestational diabetes, a type of high blood sugar that develops during pregnancy.

The findings show that taking any combination of antidepressants and antipsychotics during pregnancy is linked to an increased risk of gestational diabetes. This risk is even more pronounced with second-generation antipsychotics. These are a specific class of medications often used to treat conditions like schizophrenia or bipolar disorder. Interestingly, the data did not show a significant link for first-generation antipsychotics.

Because these results come from observational studies, they show a link rather than a direct cause. This means that while the connection is clear, more research is needed to understand exactly why it happens. Doctors can use this information to better monitor the health of pregnant patients who need these medications, ensuring they get the right support for both their mental health and their physical well-being.

What this means for you:
Some medications for mental health during pregnancy are linked to a higher risk of gestational diabetes.

Common questions

What medications were linked to gestational diabetes?

The study found that any combination of antidepressants and antipsychotics was linked to an increased risk of gestational diabetes. Specifically, second-generation antipsychotics showed a significantly higher risk. These medications are commonly used to treat conditions like depression, anxiety, and bipolar disorder.

Are all psychiatric medications risky during pregnancy?

Not all medications showed the same results. While antidepressants and second-generation antipsychotics were linked to higher risks, first-generation antipsychotics did not show a statistically significant association with gestational diabetes in this review.

Does this mean these medications cause gestational diabetes?

The study shows a link between these medications and gestational diabetes, but it does not prove that the drugs cause the condition. Because the data comes from observational studies, the exact cause of the link is not yet certain. Talk to your doctor about your specific treatment plan.

BACKGROUND: Antidepressants and antipsychotics are commonly prescribed for psychiatric disorders such as schizophrenia, bipolar disorder, major depressive disorder, and severe anxiety disorders. Psychotropic medications are increasingly prescribed during pregnancy to manage severe mental illnesses. Concerns have been raised about their metabolic side effects, including the risk of gestational diabetes mellitus (GDM). This study aimed to systematically review and meta-analyze existing evidence on the risk of GDM development in pregnant women with prenatal exposure to two common psychotropics, antipsychotics and antidepressants. METHODS: We conducted a systematic search of PubMed, Scopus, and the Web of Science, up to June 2025, identifying observational studies reporting GDM outcomes following the use of psychotropic medicines during pregnancy. Eligible studies were reviewed, and pooled relative risks (RRs) were calculated using a random-effects model, with subgroup analyses based on medication classification. RESULTS: Twenty-one studies were included in this review and meta-analysis. The pooled adjusted RR for GDM among women exposed to any antipsychotics and antidepressants during pregnancy was 1.43 (95% CI: 1.17,1.69), and 1.19 (95% CI: 1.10,1.27). Second-generation antipsychotics (SGAs) were associated with a significantly higher risk of GDM (RR = 1.6, 95% CI: 1.23, 1.97). First-generation antipsychotics showed no statistically significant association. CONCLUSIONS: Prenatal exposure to antipsychotics, particularly SGAs, and antidepressants is associated with an increased risk of GDM. Clinicians should consider these risks when prescribing psychotropic medications during pregnancy and ensure appropriate metabolic monitoring.
