In plain words

A selective serotonin reuptake inhibitor, or , is a class of antidepressant medicine. It is used for depression and anxiety disorders, which are common in pregnancy and after birth. It is the same class described in the SSRI entry. Mothers who take one are often asked about it at prenatal and postpartum visits, including how it fits with breastfeeding and with the baby's health. Research on SSRI use in pregnancy is extensive, and the findings are summarized in the SSRI entry. Whether a medicine is right is a decision made with a prescriber, who knows the full history. This entry describes the class. It does not recommend a medicine.

Transfer into breast milk is generally low relative to maternal dose, and and InfantRisk maintain drug-specific summaries. This entry is descriptive and carries no dosing information.
