Symptoms of major depressive disorder (MDD) include persistent sad mood, feelings of hopelessness or guilt, decreased energy, irritability, and more. If untreated, MDD can interfere with the ability to work, study, sleep, eat, and enjoy once pleasurable activities. MDD occurs most commonly in females between the ages of 25 and 44. This puts women of childbearing age at a particularly high risk for developing the disorder. However, very little research has been done to determine the safety of antidepressant use during pregnancy and how the medication may affect the baby. This study will determine the safety of antidepressant use during pregnancy for both the mother and the child.
