How long dose Xanax stay in you urine system? Thanks

"Half Life" is a measurement of how long it takes a medicine to be reduced by half in your blood.

Xanax's half life is around 11 hours, but can range from 6 to 26 hours. There is a slow release version of Xanax, and while it maintains a more level therapeutic amount in your blood, studies have shown that it has about the same elimination time as the regular version.

If you are asking this because you have questions about side effects or the drug's effectiveness, please contact the prescribing physician immediately.
