The World Health Organization recommends breastfeeding newborns,but it is counterproductive if the mother presents a disease that affects this natural process⁽¹⁾, such as possible acute or chronic pathologies in the life cycle of pregnancy, as well as in lactation; one of them is postpartum depression (PPD), a frequent psychiatric complication in the puerperium that influences the health of the mother and the infant, such as early interruption or continued breastfeeding⁽²⁾. Pharmacological treatment consists of the administration of antidepressants, considering the risks and advantages, some SSRIs stand out for their lower detection in breast milk⁽³⁾; for this reason Sertraline may be the safest, the infant ingests small amounts and is generally not detected in the plasma. It is also the most used during lactation according to most researchers⁽⁴⁾. Mothers may need breastfeeding counseling due to the uncertainty of continuing or not breastfeeding⁽⁵⁾.
