xanex

how long does xanex stay in your system?

[MrGreen]

Depends how long you have been taken it for. If you mean one tablet, between four to six hours and it will wear off. If you mean you have been taken xanax for a long time, then don't just stop. It is dangerous thing to do. Maybe re-word your question and tell us exactly what you mean.

As with MrGreens question, we need to know more precisely what it is you're asking. If you're wondering how long one pill will remain in your system, it is virtually gone within 4-6 hours. The half-life of Xanax is 12-15 hours. One needs to understand the concept of "half-life" to be able to figure out exactly how long a drug will remain in your system.

The concept of half-life is best understood by an example. Morphine provides a good illustration. The half-life of morphine is approximately 3 hours. By definition, this means that body stores of morphine will decrease by 50% every 3 hours.....regardless of how much morphine is in the body. If there is 50mg of morphine in the body, 25mg (50%) will be lost in 3 hours; if there is only 2mg of morphine in the body, only 1mg (50%) will be lost in 3 hours. Note that in both cases, morphine levels drop by 50% during an interval of one half-life. (3 hours)
If you took a 2mg dose of Xanax, within 12-15 hours you would have lost half, or 1mg. Within the next 12-15 hour window, you would lose 1/2 of THAT amount or .50mg. This sequence would follow the interval of one half-life, which for Xanax is 12-15 hours, after which all of the medication would eventually be out of your system.

If this was not the information you were looking for, sorry for the pharmacological lecture.

P.S.
Are you concerned with Xanax showing up in a pee test?
