Question: how long does it take for xanax to leave your blood system?
Answer: The average half-life of Xanax in the blood is 11.2 hours in healthy adults, meaning that half of the drug has been metabolized and eliminated in the urine in that time frame. It takes about five half-lives for 98% of a drug dose to clear the body, so Xanax takes 2–4 days to be fully eliminated from the body.
