Larry, I have been on Xanax 0.25 mg three times a day for the last twenty years (20) for Panic Disorder. I had my initial Panic Attack while a student in Air Traffic Controller School. My max daily dosage is 1.5 mg-1.75 mg, and I can feel myself building up a tolerance to it.ypically in cases of treating generalized anxiety or social anxiety, a person only will need about 0.25 mg to 0.5 mg to alleviate symptoms. Even for panic attacks, the maximum recommended dose is only 0.5 mg.
