A controllable dispensing device for use by a drug therapist for the unsupervised administration to a patient of a drug therapy regimen. A field unit is loaded with a plurality of medication containers in a predetermined sequence. Along with the medication, a program of dosing times is stored in an electronic memory of the field unit. This program is defined using a computerized base unit and is transferred to the field unit via an interface between the base and field units. The field unit includes a display and alarm for altering the patient as to the times for dispensing and administering the medications in the containers. The field unit permits dispensing of containers only in accordance with the predefined schedule and records the actual times of container dispensing. Later, the field unit can be debriefed by the base unit via the interface and the base unit prepares a report of medication compliance for the drug therapist.
