Acute phase. On average, withdrawal from Xanax lasts 2 months or more. A good rule of thumb I like to go by is the 90 day rule for any psychiatric medication. In most cases, withdrawal symptoms subside by the third month of not taking the medication.
In older or obese people, or those with liver disease, Xanaxâs 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.
