i was on lamictal, lexapro and buspar. i stopped them all a week before i got pregnant with my 4th child. he was born with a severe case of cleft lip and palate. i have heard this was caused by the pexapro left in my system. i am planning to have another child and i am now on seroquel xr, lexapro, and xanax. Was it the lexapro that caused the cleft since it runs in neither family and my first 3 children has had no problems, but i was on no meds then.
