Xanax, which is the brand name for alprazolam, is a commonly prescribed benzodiazepine that’s mainly used to help with anxiety disorders and panic attacks. It acts quickly by boosting the calming effects of GABA, a neurotransmitter in the brain, which helps ease excessive nervousness and encourages relaxation. While Xanax can be effective for short-term relief of anxiety symptoms, it does come with some risks, including dependence, withdrawal, and sedation. It’s important to use it only under the supervision of a healthcare professional.
