Some benzodiazepines have to be taken 2 to 4 times within 24 hours for all-day relief. You may feel calm after you take the medicine but then lose that feeling before it's time to take the next dose. That’s because the medicine’s effects can wear off between doses if not taken as directed by your doctor.

With XANAX XR, one dose gives you all-day relief from the symptoms of panic disorder. When you swallow the pill, it does not melt right away. Instead, a soft gel coating forms around it. The gel coating helps the pill last longer in your body. This allows the medicine to be released more slowly, giving you all-day relief.

As shown in the diagram, XANAX XR remains steady in your body throughout the day, compared with XANAX® (alprazolam) (see full prescribing information for XANAX). So you don't need to worry about your medication wearing off too soon or fluctuating up and down between doses.
