Major Depression Postpartum Onset (PPD) is a chronic relapsing illness which affects not only maternal mood but also the baby and family. Therefore, it is critical to aim for timely intervention once the diagnosis is made. Studies have shown that antidepressant medications are effective in treatment for moderate to severe PPD. Common reasons for noncompliance and discontinuation of antidepressant medications in the postpartum period are the side effects associated with different antidepressants. To choose an antidepressant medication with proven efficacy and a tolerable side effect profile is key in order to maximize adherence to pharmacotherapy.
