I have SEVERE anxiety and panic attacks. It's genetic. I'm 5 weeks pregnant on Lexapro and Hydroxyzine. I'm only taking the hydroxyzine as needed. (3 times a week) at 25mg. Do the benefits outweigh the risk? Please help. I'm a first time mom.I am worried that it will. Wise defects to the baby. But me being under stress can cause even bigger issues.
