Purpose
This study aimed to examine the association between discontinued and continued use of antidepressants and risk for gestational hypertension (GH) and preeclampsia (PE).
Methods
Data from the MotherToBaby pregnancy studies from 2004 to 2014 were analyzed to compare women who discontinued antidepressant use ˂20 weeks of gestation (discontinuers) and women who continued antidepressant use ≥20 weeks of gestation (continuers) to non-users for risk of GH (blood pressure ≥140/90 mmHg on two or more occasions at ≥20 weeks of gestation) and PE (GH with proteinuria). Maternal data, including exposures and study outcomes, were collected through multiple phone interviews. Medical records were used to validate outcomes. Odds ratios (ORs) and 95 % confidence intervals were estimated using logistic regression. Risk for GH and PE were also assessed within antidepressant drug classes.
Results
Data from 3471 women were analyzed. Continuers were significantly at risk for GH (adjusted odds ratios (aOR) 1.83; 95 % CI 1.05, 3.21) after adjustment. Analyses by drug class showed that continued use of serotonin-norepinephrine reuptake inhibitors (SNRI) increased risk for GH; however, of the 21 women who continued to use SNRI, only 3 developed GH. Continuers who used two or more antidepressant drug classes had increased risk for PE. Selective serotonin reuptake inhibitors or other antidepressant use was not associated with increased risk for GH or PE. No significant associations with PE or GH were found for discontinuers.
Conclusions
Results suggest that women who continued to use antidepressants in the second half of pregnancy are at risk for GH and PE. No significant association was found among discontinuers.
