Xanax doesnt flush out with water and it takes a long time to fully metabolize. I took one dose prior to a dental appt and had it show on a pre-employment screen about 4-6 weeks later and that is supposed to be the detection time for chronic use but I took only one dose (1mg) prior to a dental appt because that is the ONLY time I use Xanax so I know exactly when I took it and how long it had been. I have panic attacks, and never take these besides this one time. Answer. Xanax, or alprazolam, is an anti-anxiety medication that is in a class of compounds called benzodiazepines. As you know, it can be an effective treatment for a number of anxiety disorders, such as panic disorders. However, it also has a high potential for abuse and/or dependence. In older or obese people, or those with liver disease, Xanax's half-life is longer, as long as 40 hours. It takes several half-lives to eliminate a drug completely. So for most people, there may still be a small fraction of Xanax in your blood two days or more after taking a single pill. In order to address your particular concerns and questions regarding this medication, I recommend that you schedule an appointment to speak with your doctor, so that he or she can address your individual case. Having said that, the average half-life of xanax is approximately 11 hours. This means that half of the medication will have left the body by that time. On the other hand, it is important to note that everyone metabolizes medications differently, so this half-life can range from 6 to 26 hours, depending on the person and the dose and frequency of the use of the medication. However, Xanax remains in the bloodstream long after its anti-anxiety effects have worn off. Xanax's average half-life is 11 hours. This means that it takes an average of 11 hours for the body to eliminate half the Xanax dose. I know everyone is different but this is my story. I don't take Xanax but I took 1 mg a day for 7 days straight and than stopped completely, my system was totally clean before I started taking them. My job does test so I had purchased some drug screen urine test cards for benzos just to see how long it would take before it got out of my system. I figured probably 72 hours, well it actually took 8 days for my tests to start reading a negative result. Here's what my pdoc told me to help the xanax get in your system quicker. Take a drink of water and make sure your mouth is wet. Chew up the xanax and then stick it between your upper lip and teeth. Leave there. It will kick in about 10 to 15 mins if not sooner. I do this when having a really bad attack. Xanax is a little bitter but you can actually get used to it. When it's been long enough take another drink of water and swallow it all. This helps it to get into your blood stream much quicker rather than going through your stomach lining. I hope this helps. As for how many to take a day I would talk to your dr about that. deleted_user 12/03/2007 I used to take Klonopin, then Ativan and my recent doctor finally put me on Xanax, which is truly a lifesaver. Zocdoc " Answers " I took 2mg xanax 1 time. How long will it stay in my system? I have panic attacks, and never take these besides this one time deleted_user 12/02/2007. I take 1 mg twice a day so I think one of mine is like 4 of yours but I wouldn't suggest taking that many if your not used to it, as far as how long it takes it usually takes mine about 15 to 30 min. Sometimes just the fact that I took one makes me feel better instantly. Details: I took .5 of alprazolam two days ago and 1mg of it yesterday. (Two .25 pills two days ago and four .25 pills yesterday). I am 5'7 and 170 pounds with a very high metabolism, I am moderately active and I drink an immense amount of water normally. Seeing as I am very athletic I have very little fat on me. Query: how long does it take for daily xanax to leave your system
