How long does xanax stay in your system?
It depends on your age and health. In young to middle-age people, the half-life is 11.2 hours, so 97% of it would be out of your system in 56 hours. In older people, the half-life is 16.3 hours, so 97% of it would be out of your system in 81.5 hours. If you have liver disease, it's longer.
