How much Xanax can I take at one time?

Normal single doses usually range from 0.25 mg to 1 mg. Your doctor should make the right decision on what to take. Those who do not take Xanax regularly usually shouldn't take more than 1 mg at a time. When I first started Xanax, I was put on 1 mg three times daily. It took away all my anxiety and faintness.
