Alprazolam, commonly known by its brand name Xanax, is a prescription medication used to treat anxiety and panic disorders. Because it affects the central nervous system, it is classified as a controlled substance in many countries, including the United States. This means its sale, distribution, and use are strictly regulated. If you are wondering whether you can buy alprazolam online using a credit card, it’s important to understand the legal, medical, and safety aspects first.
