A controlled dispensing system includes a dispensing fixture and a server system coupled to the dispensing fixture via a communication network. The dispensing fixture is configured to obtain via an input peripheral a first identifier associated with a controlled product and a second identifier associated with a dispensing requester; transmit the first and second identifiers to the server system; receive an approval notification from the server system; and instructing the dispensing mechanism to dispense the controlled product. The server system is configured to obtain a limit threshold corresponding to a maximum number of products associated with the first identifier that may be dispensed over a predetermined time period for a dispensing requester associated with the second identifier; and determine whether approving the dispensing operation would violate the limit threshold, and if not, update a dispensing history associated with the second identifier and transmit the approval notification to the dispensing fixture.
