A computerized reminder system collates medical prescription information such as provided by commercial retail pharmacies to customized schedules for administration of medication and therapy to patients. The system broadcasts reminder information via radio frequency wireless transmissions over a wide area network subsystem to portable receivers uniquely associated with specific patients. The patients receive real-time reminders directed only to them to take medicine. Patients receive only their own respective reminders and do not obtain reminders for other patients who subscribe to the system.
