Alprazolam (Xanax) 0.25mg - taken as needed

This stuff kicks *** against panic attacks, but it does have addictive traits and you can only be prescribed so much of it at a time.

I was prescribed a daily med called Sertraline 50mg (a.k.a. Zoloft) for anxiety as well, but I'm personally too reluctant to take it. I prefer taking medication only as I need it.
