It depends on the psychiatrist and the patient. The psychiatrist is a medication expert and may feel some other kind of medication is most suited for your symptoms.

Benzos are taken by many people. They can be taken regularly but they become less effective because one builds up a tolerance. So, a higher does becomes necessary to achieve the same effect.

I was prescribed Xanax on a kind of trial basis. I am open about my drug past and I have no desire to be in that place again. I was not sure I even wanted to try Xanax but after quitting smoking my anxiety was very interfering in my daily life and my work and was not letting up. So, my doctor (I don't see a psychiatrist) prescribed a small amount to see how it would go. I found that taking less than the prescribed amount worked well for me, and taking it only when needed instead of regularly throughout the day worked best for me also. So that initial one-month prescription lasted me several months and the next one did also. So now I get a refillable Rx (1 refill) and it sometimes expires because I take it so rarely. I began therapy since the time I was prescribed and that has helped my anxiety tremendously.

So, each psychiatrist/doctor is different as is each patient and I think this is one thing you will have to wait and see. It isn't something you can know ahead of time.
