What is the minimum therapeutic dose of clonazepam for the management of panic disorder? is 0.5 mg a day okay?

It looks like: clonazepam is your only psychiatric medication. I try to treat with selective serotonin reuptake inhibitor (SSRI's) or buspar (buspirone). I try to use Benzodizapines (Clonazepam is a benzo) sparingly when we are starting sSRI's and there is not yet a therapeutic effect. I try to avoid long term use of benzodiazapines if possible.
