The levels of the drug in the blood depend upon the amount of the drug taken. The average half life of the drug in adults is about 12 hours however it may range between 9-16 hours for different individuals. It means that the drug is reduced to half the amount originally taken after 9-16 hours of the usage. As a person ages, the half life of the drug increases and the effects produced by it also get more severe. Other than this there are a number of factors that may influence the time drug stays in the system of the user such as:
- Height and weight of the user:
The overall body mass of a person has a significant role in determining the time Xanax stays in the system for. Greater the mass of the body, the more area is available for the drug to diffuse. The body mass is also important to determine the dose that should be prescribed to a patient. It takes less time for larger individuals to get Xanax out of their system. Smaller people tend to test positive for the drug for relatively longer periods of time.
- Age of the user:
Age of the user influences the time taken by the drug to exit the body. As a person ages, the body systems and metabolism wear out so they cannot work as efficiently as they do in a young person. For elderly people, the half life of Xanax may reach up to 16 hours. This is the reason doctors prescribe it in small amounts to elderly patients. The risk of Xanax overdose also increases with age.
- The amount taken by the user:
The more amount of the drug is taken by the user, the longer it takes for the body to remove it. When taken in larger amounts, it takes much longer for the metabolic system of the body to clear it out.
- The time drug was taken for:
Some user may retain the drug in their body for much longer periods of time than the others. It is because when the usage is prolonged, it becomes a part of fat cells of the body. So when the drug is quit, body not only has to remove it from the blood but also from the fat cells. The process can be significantly long.
- Efficiency of the user’s metabolic system:
How fast the metabolism of a person works is very important in this regard. Metabolic system is the mechanism of the body by which it breaks down substances entering it either to generate energy or to detoxify the body. People with an active lifestyle such as those who regularly exercise tend to have a faster metabolic system. So as a result, Xanax is removed from the system of an active person much faster than a person with slow metabolism.
- Genetic disposition of the person:
Genetics play an important role when it comes to how a certain drug affects a person and for how long it stays in their system. For some people it takes much lower doses of the drug to produce its effects. Likewise, some people are more likely to retain it in their systems than the others.
- Overall health of the user:
The physical and mental health of the patient is important in the process of withdrawal and recovery. A person with sound body is likely to get rid of the menace relatively easily. There are certain organs in the body that work to detoxify the system such as liver and kidneys. If these organs are intact and function as they should, body will be detoxified more rapidly. This is the reason the diet and health of the person should be given due importance during the process of treatment.
Even though Xanax is a short acting drug, it may take relatively long for the body to completely remove it especially, when it is taken for long periods of time. It can take several weeks and even a month for the body to completely detoxify it.
