Anxiety
"I have always lived with anxiety and was taking Zoloft daily. I had a car accident in May that spiraled my anxiety out of control. My doctor put me on this in addition to Zoloft.  Not only has hydroxyzine helped with my anxiety, It has prevented me from having panic attacks and allowed me to wean off the Zoloft.  My panic attacks used to also make me nauseous and Hydroxyzine prevents that.  I have had no side effects at all.  Zoloft side effects were weight gain and diarrhea."
