Xanax, whose generic name is alprazolam, is a benzodiazepine medication commonly prescribed to treat anxiety disorders and panic disorders. It works by increasing the activity of GABA in the brain, which helps calm excessive nerve activity and reduce symptoms such as nervousness, tension, and panic attacks. Xanax is known for its relatively fast onset of action, making it useful for acute anxiety episodes. Doctors generally prescribe it carefully and for limited durations because benzodiazepines can lead to dependence if used improperly. The medication is usually taken in tablet form and the dosage is determined by the healthcare provider based on the patient’s condition. Side effects may include drowsiness, dizziness, fatigue, and difficulty concentrating.
