Xanax is a drug that is used to alleviate the effects of anxiety disorders, panic disorders, and anxiety caused by depression. Additionally, it has the chemical name of Alprazolam. However, many individuals have abused the drug due to the euphoric effects it can cause its users.

Because of the drug’s effectiveness and affordability, it has become one of the most prescribed psychoactive drugs in the United States. This medication works by attaching to GABA receptors present in the brain. This, in turn, causes a nerve-calming effect on the person taking it.

Elimination Half life Of Xanax

Xanax has a half-life of 9 to 16 hours. This means that after that time, only half of the amount of the drug you consumed will remain in your system. It will continue to be eliminated that way until it is virtually undetectable. (1)

On average, it takes four days to get rid of Xanax entirely. However, this may vary according to the factors listed below. With the numerous factors involved, it is virtually impossible to determine on your own the exact amount of time it will take.

What Factors Affect The Metabolism Of Xanax In Your Body?

There is no definite length of time Xanax will stay in your system. It can be affected by various existing factors both in within you and around you. Listed below are some of the variables you need to take into account in estimating the span of time Xanax will stay in your body:

  • Drug Dosage: Ironically, those who are taking higher dosages of Xanax can metabolize and release Xanax at a much quicker rate than those taking lower dosages.
  • Age: The flushing out of Xanax in the body is slower for older individuals than younger people.
  • Height, Weight, and Fat: Studies have shown that there is a positive correlation between these three and the length of time it takes for the body to get rid of the drug. The logic behind here is if Xanax is distributed to a larger area, it will metabolize a lot quicker.
  • Liver and Kidney Functions: The liver and kidneys are the once that handle every drug that enters our body. Hence, the healthier they are, the faster and more efficiently they can excrete the drug.
  • Genetics: A study has found that Asians excrete the drug 15 to 25 percent quicker than Caucasians. This may be because of genetic variations in the CYP450 isoenzymes. Such variations can determine whether or not you will be a fast or a slow in metabolizing the drug.
  • Metabolic Rate: The higher the metabolic rate, the quicker the drugs can be eliminated from the system. (2)

Importance Of Knowing How Long A Drug Last

Knowing whether or not a particular drug is still present in your body can protect you from a dangerous situation. Xanax can cause side effects which can impair your ability to do certain activities with full control. For instance, engaging in strenuous activities like driving or operating machinery is very dangerous. Most importantly if you are feeling extremely drowsy or dizzy due to Xanax.

Having drugs in your system in particular situations can endanger not just physically but also legally. There have been reports of false positives in drug tests due to the presence of Xanax in the body. Hence, it is best to wait for the drug to clear before taking any drug tests.
