Xanax is the branded version of Alprazolam, an anti-anxiety pill, which is mainly prescribed in the treatment of anxiety problems and panic disorder. It owes its origin to a category of drugs known as benzodiazepines. Xanax works by calming the brain and the central nervous system for a quiet relaxation. Always take this medication as per the instructions of a physician and in correct dose. Anyone using it for more than a fortnight without physician’s advice is likely to get addicted to it. Use of it may prompt manageable side effects such as headache, drowsiness and nausea. Those experiencing hallucination or agitation after its use should immediately get in touch with a physician. Sleep Tab, a trusted online pharmacy, sells Xanax UK at affordable prices.
