How Long Does Xanax Stay in Your Body?

Xanax is the brand name of alprazolam, a Schedule IV controlled substance, meaning it has a low risk of abuse and dependence. It is classified as a benzodiazepine class of drugs and is prescribed for anxiety, panic attacks, and generalized anxiety disorder (GAD). It is fast-acting, providing relief from anxiety symptoms in an hour or so, sometimes within half an hour.

Xanax works by enhancing the effects of a natural chemical in the brain called gamma-aminobutyric acid (GABA). When it binds to GABA receptors, it increases GABA’s calming effects, producing a sedative and tranquilizing response. This action helps relieve symptoms of anxiety, panic disorders, and stress-related tension by slowing down overactive brain signals.

Whether Xanax is still in your system depends on many factors. These include your weight, age, liver function, and dosage. Your metabolism and how often you take Xanax also matter. A healthy adult usually metabolizes Xanax in about 11 hours. This is roughly how long it takes to leave the body. For many people, Xanax is fully cleared from the blood in 2 to 4 days. About 65% of users fall within this range.

Detection windows can vary depending on the type of drug test, for example

  • Urine Test: If you are an occasional user, for urine tests, Xanax may be detected up to about four days after the last dose was taken, or over a week if a chronic user.
  • Blood Test: A blood test may show positive for Xanax up to one to two days after the last consumption.
  • Saliva Test: Xanax will be detectable in a saliva drug test for about 2.5 days after the last dose was taken.
  • Hair Follicle Test: Xanax can appear in a hair follicle drug test for up to 90 days since the last drug dose.

Although the extended-release (XR) form of Xanax may take longer to appear in one of the tests, as mentioned earlier. Regular use, high doses, or mixing Xanax with substances like alcohol can slow the body’s ability to metabolize it. This may extend how long the drug stays in your system.
