I would think Lexapro would have been the next logical choice after
Zoloft, and Prozac before
Zoloft. The reason
Zoloft was prescribed most likely is it appears to be the most effective for anxiety, and the next drug that came on the market, Paxil, is, along with Effexor, the most difficult drugs out there. But there was still Celexa and its newer version Lexapro to try. Buspar isn't an antidepressant, it's supposedly anti-anxiety, but hasn't proven to work well.
