Xanax has an elimination half-life that ranges from 9 hours to 16 hours in healthy adults.
This means that it will take most people within the span of 9 to 16 hours (post-ingestion) to eliminate 50% of the drug from their body. On average (among most users), the half-life of Xanax is around 12 hours. This means that most people will have fully eliminated (100%) the drug from their system within 4 days.
