Abstract

OBJECTIVE:

To assess whether the use of selective serotonin reuptake inhibitors (SSRIs), tricyclic antidepressants, mirtazapine, venlafaxine or other antidepressants is associated with late elective termination of pregnancy.

DESIGN:

Case-control study using data from national registers.

SETTING:

Denmark, Finland, and Norway during the period 1996-2007.

POPULATION:

A total of 14,902 women were included as cases and 148,929 women were included as controls.

METHODS:

Cases were women with elective termination of pregnancy at 12-23 weeks of gestation. Controls continued their pregnancy and were matched with cases on key factors.

MAIN OUTCOME MEASURES:

Association between antidepressant use during pregnancy and elective termination of pregnancy at 12-23 weeks of gestation for fetal anomalies, or for maternal ill health or socio-economic disadvantage.

RESULTS:

At least one prescription of antidepressants was filled by 3.7% of the cases and 2.2% of the controls. Use of any type of antidepressant was associated with elective termination of pregnancy for maternal ill health or socio-economic disadvantage (odds ratio, OR 2.3; 95% confidence interval, 95% CI 2.0-2.5). Elective termination of pregnancy for fetal anomalies was associated with the use of mirtazapine (OR 2.2, 95% CI 1.1-4.5). There was no association between the use of any of the other antidepressants and elective termination of pregnancy for fetal anomalies.

CONCLUSION:

The use of any type of antidepressants was associated with elective termination of pregnancy at 12-23 weeks for maternal ill health or socio-economic disadvantage, but not with terminations for fetal anomalies. Further studies need to confirm the findings concerning mirtazapine and termination of pregnancy for fetal anomalies.

KEYWORDS:

Antidepressants; fetal anomaly; socio-economic disadvantage; termination of pregnancy
