The treatment of postpartum depression: minimizing infant exposures

The first 3 postpartum months represent a high-risk period for psychiatric illnesses. This article reviews the prevalence and diagnostic criteria for postpartum illnesses, including the "maternal blues," postpartum depression, and postpartum psychosis. Pharmacologic treatment of these disorders is often complicated by a patient's desire to breast-feed, yet there are no controlled trials of antidepressant treatment during lactation. Infant exposure and limitations to monitoring infant sera are reviewed. Lastly, a model and guide for reducing fetal and infant exposures is presented.
