Xanax is a prescription medication commonly used to treat anxiety and panic disorders. It belongs to a class of drugs called benzodiazepines, which work by enhancing the effects of a neurotransmitter in the brain known as GABA. This helps to promote relaxation and reduce feelings of anxiety. While Xanax can be effective for short-term relief, it may lead to dependence if used for extended periods. Common side effects include drowsiness, dizziness, and confusion. It is important to use Xanax under the guidance of a healthcare professional to manage dosage and duration safely.
