Abstract: A system for contacting customers of a pharmacy automatically to remind them that their prescriptions need to be refilled does so using a computer, memory, and automatic telephone dialing and voice synthesizing equipment. Information concerning each customer and his or her prescription is placed in a database in the memory. A schedule file which lists customer name, phone number, the drug prescribed and refill due date is created from this information. The schedule file is kept in chronological order by refill due date. At selected times, customers whose prescriptions are due to be refilled within selected time periods are automatically contacted by the computer using the automatic telephone dialer. When the telephone is answered, the voice synthesizer identifies the customer by name, the prescribed drug and prescription number. The voice synthesizer then reminds the customer that the prescription is due to be refilled if the medication was taken as prescribed.
