Context Pregnancy has historically been described as a time of emotional well-being, providing "protection" against psychiatric disorder. However, systematic
delineation of risk of relapse in women who maintain or discontinue pharmacological treatment during pregnancy is necessary.

Objective

To describe risk of relapse in pregnant women who discontinued antidepressant medication proximate to conception compared with those who maintained treatment with these medications.

Design, Setting, and Patients

A prospective naturalistic investigation using longitudinal psychiatric assessments on a monthly basis across pregnancy; a survival analysis was conducted to determine time to relapse of depression during pregnancy. A total of 201 pregnant women were
enrolled between March 1999 and April 2003 from 3 centers with specific expertise in the treatment of psychiatric illness during pregnancy. The cohort of women was recruited from (1) within the hospital clinics, (2) self-referral via advertisements and community outreach detailing the study, and (3) direct referrals from the community. Participants were considered eligible if they (1) had a history of major
depression prior to pregnancy, (2) were less than 16 weeks' gestation, (3) were euthymic for at least 3 months prior to their last menstrual period, and (4)
were currently or recently (<12 weeks prior to last menstrual period) receiving antidepressant treatment. Of the 201 participants, 13 miscarried, 5 electively
terminated their pregnancy, 12 were lost to follow-up prior to completion of pregnancy, and 8 chose to discontinue participation in the study.

Main Outcome Measure

Relapse of major depression defined as fulfilling Structured Clinical Interview for DSM-IV [Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition] Diagnosis (SCID) criteria.

Results

Among the 201 women in the sample, 86 (43%) experienced a relapse of major epression during pregnancy. Among the 82 women who maintained their medication throughout their pregnancy, 21 (26%) relapsed compared with 44 (68%) of the 65 women who
discontinued medication. Women who discontinued medication relapsed significantly more frequently over the course of their pregnancy compared with women who maintained their medication (hazard ratio, 5.0; 95% confidence interval, 2.8-9.1; P<.001).

Conclusions

Pregnancy is not "protective" with respect to risk of relapse of major depression. Women with histories of depression who are euthymic in the context of ongoing
antidepressant therapy should be aware of the association of depressive relapse during pregnancy with antidepressant discontinuation.
