panic disorde
"Xanax has been an extremely effective medication. I have severe panic with agoraphobia and failed to respond to therapy, clonazepam, paroxetine, other benzodiazepines, antidepressants, AED's, beta-blockers, and others. I have taken up to 12 mg/day but I find that 4-6 mg/day is best. Side effects are non-existent nor have I ever experienced any form of withdrawal. Incidentally Xanax (along with imipramine) have been shown to be effective for years of continuous use. Great for either short-term use, and if needed, long-term use."
