In the UK, Xanax is typically prescribed for short-term relief of severe anxiety symptoms. It’s important to use this medication under the guidance of a healthcare professional, as it may lead to dependence with prolonged use. Always follow the prescribed dosage, and avoid mixing with alcohol or other depressants.
