Is citalopram (antidepressants) at 40mg daily safe during pregnancy?

Yes: At this dose the chances of anything bad happening to baby are about 1 in 2000 for pulmonary hypertension. The best studied antidepressants in pregnancy are Prozac (fluoxetine) and sertraline (zoloft). Bottom line, there is minimal risk to baby and there is risk to mom for untreated depression in pregnancy. It's an important decision to make with your doctor, knowing the risks and benefits. Best of luck.

Treatment choices: The mainstream thinking is that the benefits of treatment should outweighs the risks of treatment during pregnancy. That is a consideration to be taken by doctor and patient in view of the history of the condition and the actual mental status of the patient at that time. Most doctors will prefer to withdraw the medications if possible. It is a real challenge for both, patient and practitioner.
