Is it constant or situational?
If it's long-term, constant, and for a reason you can't pinpoint (Generalized Anxiety Disorder), they might try something that will work long-term. I'm on neurontin for it now and it's working pretty well.
I'm also on a steady dose of klonopin because my anxiety/panic is pretty bad. That helps a lot, although is slightly sedating.
If it is situational, and in the moment, they would probably give you xanax to calm down panic attacks and such. Or ativan.
But you can look up all these online to find out what you think you might benefit from the most as well.
