Gosh, I don't remember. I started on antidepressants many years ago, so I don't have a clue.
I do know that almost all that I HAVE been on have worked. I've just had to change to others because they stopped workiing. After you're on them for so long, they just don't work anymore and you have to use another. I'm now on Cymbalta, the maximum dosage of 130mg per day with Abilify 2mg. per day. It works great!
Take care! Hugs, Lee
