In pharmacy practice, a perpetual inventory of Schedule II (CII) medications is indeed a requirement only in certain settings, specifically in institutions like hospitals. This requirement stems from the high potential for abuse associated with controlled substances and the need for strict accountability and regulation. By maintaining a perpetual inventory, pharmacies can ensure that they are accurately tracking the receipt, dispensing, and loss of these medications, thereby promoting safe and responsible handling.
Hospitals and certain other settings face stringent regulations to prevent misuse and monitor the amounts of controlled substances that are used and stored. This accountability supports the overall goal of reducing drug diversion and maintaining public safety. In contrast, other types of pharmacy practice settings, such as independent or retail pharmacies, may not be subject to the same regulatory demands regarding perpetual inventories. Instead, they might adhere to less stringent methods of inventory management for controlled substances.
