What are some possible side affects to the baby when you take Zoloft (sertraline) 150mil during entire pregnancy?

Minimal. The side effects of ssris like zoloft on an infant exposed in utero are very rare and almost non-existent. Some infants have developed pulmonary hypertension but it is more common with Paxil and Effexor (venlafaxine) than zoloft, and even then it is very rare. Be aware that depression itself can also have a negative impact to the baby and that has to be weighed against the risk of the medication.
