title: Relapse of depression during pregnancy following antidepressant discontinuation: a preliminary prospective study.
abstract: OBJECTIVE
  Pregnancy has frequently been referred to as a time of emotional well-being for patients. However, systematic data about the risk for relapse of depression during pregnancy are sparse.
  
  
  METHODS
  We completed a longitudinal cohort study of thirty-two (N = 32) women with histories of depression who were euthymic at conception and who either discontinued or attempted to discontinue antidepressant therapy proximate to conception. Subjects were prospectively followed across pregnancy once per trimester using structured clinical interviews. Rates of relapse and time to relapse were examined. Factors distinguishing the population with respect to risk for relapse including demographic characteristics and illness history were also examined.
  
  
  RESULTS
  Seventy-five percent (N = 24) of patients relapsed during pregnancy. The majority of relapses (79%, N = 19) occurred in the first trimester, and relapse was more prevalent in women with histories of more chronic depression.
  
  
  CONCLUSIONS
  Pregnancy is not "protective" with respect to risk for relapse of depression. Careful treatment planning is necessary for those women on antidepressants who plan to conceive or who become pregnant.
