alprazolam (xanax) is an anxiety-relieving medicine that starts to work within about an hour after taking the pill. the level of drug reaches a peak in the bloodstream after one to two hours and its felt effects last on average about 5 hours. 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. 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. people who take xanax on a regular basis maintain a higher drug level in the bloodstream and it could take several weeks to eliminate all the xanax from the body. xanax is excreted from the blood into the urine and is detectable in drug tests. different drug tests have different sensitivities and may or may not detect a low level of xanax in the urine. how long does xanax stay in your system? 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. thank god i wasn't tested at work. now my system is totally clean. i am 30 male 6'0" and weigh 190 lbs. so if you take them you better give yourself a good bit of time for it to clear your system it is depend on many things like body weight/height/fat level: genetic problem: liver functionality metabolic rate age here is best guide on how long does xanax stay in your system urine and blood you can read all about that. thanks i took 2 mgs 3times a day for years and it was out of my system at the end of the 4th day
