Xanax is a central nervous system depressant that is commonly prescribed to treat anxiety and panic disorders. While it can be effective for its intended therapeutic uses, it also carries risks of tolerance, dependence, and addiction if taken long-term or abused. With regular use over 8 months or more, the body adapts and requires higher doses to achieve the same calming effect, leading to physical dependence. Abruptly stopping Xanax can cause severe withdrawal symptoms, so medical supervision is important for safely tapering off the drug.
