title: Pharmacologic treatment for postpartum depression: a systematic review.
abstract: During the past decade, the medical community has expressed a growing concern over the high prevalence of postpartum depression and the tragic repercussions of untreated illness. However, many questions persist about the pathogenesis of postpartum depression, the natural course of the illness, and the safety and effectiveness of available treatments. To summarize the data on pharmacologic treatments for postpartum depression, we performed a systematic review of four major databases to identify original research published from 1960-September 2009 that featured pharmacologic treatments for depression detected in women during the 12 months after delivery. Pharmacologic treatments included prescription drugs (antidepressants and hormones), herbal remedies, and dietary supplements. Case reports, studies examining the prevention of postpartum depression, and those including diagnosed episodes of depression preceding the postpartum period (i.e., antepartum onset) were excluded. Treatment randomization or the presence of a control group was not required for inclusion in this review. Fourteen investigations met inclusion criteria. Nine studies examined the effects of prescription antidepressants, two investigated hormones, and three featured omega-3 fatty acid supplementation. Significant heterogeneity was evident in study design and prevented a pooled quantitative analysis of treatment effects. The power of most investigations was limited, and numerous confounding biases were evident. Therapeutic effects were documented for prescription antidepressants and hormone supplementation (estrogen derivatives). Tolerability of the interventions in depressed mothers and breastfed infants was not well described. The effectiveness of omega-3 fatty acids was not evident in postpartum depression trials, although significant limitations in study methodology were apparent. Postpartum depression is a common and serious medical problem, but most cases go undetected and untreated. The need to identify safe, effective, and convenient treatments for postpartum depression is urgent, but the current state of the medical literature describing pharmacologic interventions is not impressive. Preliminary evidence documenting the effectiveness of serotonergic antidepressants and hormone supplementation should serve as an impetus for rigorous controlled investigations in the future.
