How long will one 0.5 mg xanax stay in my urine? I need to pass an employer drug screen?

I can only speak from experience. I too was on 0.5 mg which I took as needed off and on for about 6 months. It really helped me with my anxiety and panicky attacks, but our society doesn't really accept people on xanax sctripts, even though was completely legal. So I decided to quit. I stopped taking it, and 3 weeks later I had a work related drug test. I wasn't sure if it will still show up so I had my prescription ready, to explain the employer. My drug test came back completely negative, thus is safe to say 3 weeks is enough for xanax to be completely eliminated, but from what I read about xanax, 9 days should be more than enough for this benzo to leave your body. They say you should be fine 4,days after the last dose. Do you have a script for xanax? Bring it with you, if you do.

Hello canterbury. As a rule of thumb, you most probably will be fine. I've found that a six day period is unoffically the guideline. Given your dose and it being nine days, you should be allright. Regards,pledge

Unfortunately they may still show. I take Xanax 0.5mg 1-2 tabs before dental appts. I took a pre-employment drug screen six weeks later after taking one single dose and I still showed positive for benzodiazepines. Benzos store in body fat and are detectable for a long time in the urine. If you have a prescription for Xanax, as I did, it shouldnt be a problem with an employer. You will just need the pharmacy or doctors office to verify that it is indeed prescribed and they will then change it to a negative because you are then legal to have the drug in your system.
