Antidepressant use during pregnancy: navigating the sea of information

When some of my patients who are taking antidepressants learn they are pregnant, they become anxious and confront me with the following statement: "I need this medication, but have heard so many conflicting stories from my friends and on the Internet and in the media that I am not sure if I should continue taking it." How do I advise them, as I have also seen conflicting evidence in the scientific literature?

To date, antidepressants are the most studied drugs during pregnancy, with more than 30 000 outcomes examining increased risks of adverse effects on exposed infants. The results of the studies can appear to be conflicting owing to differing interpretation of statistical analysis and subsequent knowledge transfer and translation of the information. However, there does not appear to be a clinically significant increased risk of any of the adverse outcomes reported in peer-reviewed published studies that would preclude a woman from taking a needed antidepressant during pregnancy.
