Xanax, known generically as alprazolam, is a benzodiazepine commonly prescribed for anxiety and panic disorders. When taken overnight, it can help calm the mind and promote sleep. However, it's important to use it as directed by us to avoid side effects like drowsiness, dizziness, and impaired coordination, which can linger into the next day. Long-term use can lead to dependence and tolerance. Avoid alcohol and other sedatives, as they can enhance Xanax's effects.
