The mean plasma elimination half-life of Xanax is reported to be 11.2 hours. The full range is from 6.3 to 26.9 hours in healthy adults.
For a drug to be totally eliminated from your system it takes 5.5 times the half life.
If we take the maximum time of 26.9 hours times 5.5, it will be in your system for approximately 148 hours i.e. 6 days, after your final dose.

Benzos, like xanax, can embed in the fat layers of the body and take between 3 days and 6 weeks to leave. If a person has a slow metabolism and is older and heavier, it will take longer to leave than someone who is younger, with a faster metabolism and is lighter. If you are asking because you have to take a drug test, and you are taking this medication on a regular basis, it will also test positive longer than if you had simply taken it once.
