This article presents a summary of information found within the existing medical literature on the pharmacological treatment options for maternal depression during lactation and the concurrent effects on the breastfeeding infant. Existing data on safety and efficacy varies by treatment modality. Medications used to treat depression are all secreted in breast milk to some extent; however, most antidepressants are considered relatively safe to use during breastfeeding. The selective serotonin reuptake inhibitors (SSRIs) sertraline and paroxetine are present in low levels and are considered preferred agents. Safety data for other antidepressants varies, however. monoamine oxidase inhibitors (MAOIs) should generally be avoided. Available references and resources can help providers optimize treatment of maternal depression while mitigating risk to the infant. Optimizing treatment of maternal depression is a complicated undertaking, which should be made in conjunction with the provider through shared decision making with the patient. Specific properties of any proposed medication, such as the relative infant dose and side effect profile, should always be taken into account during the decision-making process.
