Hello, When a medication, such as alprazolam, is manufactured, an expiration date is assigned to it. This date is determined primarily by the specific physical and chemical characteristics of the drug. Some chemicals are inherently more stable than others, and so retain full potency for a longer period of time. Also, the expiration date assumes that the drug will be kept under cool, dry conditions. High humidity, bright lights, and high temperatures can accelerate the degradation of many drugs. Generally, medications 'expire' after two to four years from the date they are manufactured.
