There are different types of Xanax available, including immediate release and extended release formulations. The type of Xanax prescribed will depend on the individual's needs and medical history. It is important to always follow the prescribed dosage and never take more than recommended, as Xanax can be habit-forming and lead to dependence. If you are considering using Xanax for anxiety, it is best to consult with a healthcare professional first to determine if it is the right medication for you.
