Celexa and Lexapro are very similar drugs. Lexapro is supposedly a cleaned up version of Celexa with fewer side effects. Having been on both, I don't buy it. I actually felt better on the Celexa. The Lexapro really didn't do anything for me. Pristiq is another sleight of hand by the drug companies. It's nothing more than a metabolite of Effexor. Effexor is venlafaxine and Pristiq is desvenlafaxine. It seems awfully strange to me that these "cleaned up" drugs come on the scene at the very time the parent drugs are going off patent and thus available in cheaper generic versions.
Anyway, to try and answer your question, it seems to me that all (and I've been on them all) SSRIs can cause weight gain. I'm on venlafaxine (Effexor) now and I'm still a little on the heavy side. It is true that the only antidepressant that doesn't cause weight gain (and can even cause weight loss) is Wellbutrin. But Wellbutrin isn't the best medication for someone with anxiety or panic disorder. It is a very stimulating antidepressant. But it may well work for you if you're on a counteracting medication, such as a benzodiazapine.

All these drugs that are handed out like candy 'poop out' after several years of use. Your doctor will be quick to tell you it's your old symptoms returning and pump up the volume or convince you to start on yet another drug. Lexapro w/d almost killed me, as no doctor ever heard of 'tapering slowly'. I am still suffering 10 months later after going cold turkey, per my doctors instructions. (I was on such a low dose I wouldn't have w/d's...uh, no).
Listen to your body and and if something does not feel right, or you have symptoms you never experienced before...find some kind of medical professional that will listen, and not blow you off. And yes...despite the assurance I would not gain weight on the drug, I gained 22 pounds in the first six months. Oink...
I'm staying away...far far away but acknowledge most people will not suffer like I did and these drugs can be life savers.
