Which side effect is associated with the use of Remeron/Mirtazapine during pregnancy?

Mirtazapine, marketed as Remeron, is known for a couple of specific side effects, particularly sedation and weight gain. During pregnancy, many women experience changes in appetite and sleep, making the sedative effects of mirtazapine potentially beneficial for some. However, the drug is also associated with increased appetite, which can lead to weight gain—a common concern among pregnant individuals. Given these characteristics, this option reflects the well-documented side effects of mirtazapine.

In contrast, other choices may not accurately represent the known risks associated with mirtazapine. While concerns about teratogenicity (the potential to cause birth defects) and miscarriage exist for many medications during pregnancy, the evidence regarding mirtazapine specifically does not demonstrate a significantly increased risk for either. Lastly, while improving neonatal outcomes is a desired effect of many medications in pregnant individuals, mirtazapine does not show direct evidence of such improvements and is more often associated with maternal weight gain and sedation.
