Taken 2mg xanax (alprazolam) 4x a day for psd/agoraphobia taken only 7 days cuz of opiate problem went to clinic denied due to xanax (alprazolam) so how long can i be detected?

Long half-life: The elimination half-life of xanax (alprazolam) is about 11.2-26.9 hours. It takes almost 6 elimination half-life's for a drug to be cleared from the human body. Well... It could take a maximum of 161.4 hours or 6.7 days (6 x 26.9 hours) for xanax (alprazolam) to be completely eliminated. Rec. See your prescribing physician to express your concerns.
