Xanax is a generic name for alprazolam. This medication is primarily 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 called gamma-aminobutyric acid (GABA) in the brain. Xanax helps to reduce excessive anxiety, nervousness, and tension. It may also be prescribed for other conditions such as insomnia, seizure disorders, and alcohol withdrawal symptoms. However, it is important to note that Xanax should only be used under the guidance and prescription of a healthcare professional, as it can be habit-forming and has the potential for abuse.
