Paxil came next, and got approved for both depression
and panic disorder, but has always been used for all types of anxiety. Then
Luvox, which chose OCD as its "special" benefit. And so on. So while Celexa wasn't approved specifically for anxiety conditions, Lexapro, the newest model of Celexa, was. Of course, it doesn't take much, you only need 500 mildly anxious people and double blind studies and walla! FDA approval.
