Sertraline shows lower placental transfer than fluoxetine and fewer metabolic enzyme interactions, supporting its preferential use in pregnancy.
In perinatal care, sertraline is generally preferred over fluoxetine due to more favorable pharmacokinetics. Sertraline generally demonstrates lower placental transfer than fluoxetine, which may reduce fetal exposure. This difference may reduce fetal exposure and neonatal transient side effects with sertraline.
Dose adjustments are recommended for both agents in cases of hepatic impairment, with special consideration for CYP2D6 metabolizer status in fluoxetine use. Neither drug requires routine renal adjustment, but both should be used cautiously in end-stage renal disease with dialysis.
When initiating SSRIs during pregnancy, clinicians typically begin at a low dose and titrate gradually, with sertraline commonly used at modest starting doses. Fluoxetine may be associated with prolonged neonatal adaptation concerns near term, and sertraline is commonly preferred based on available safety data. Always weigh benefits against uncertain long-term neurodevelopmental outcomes, and involve multidisciplinary input early.
