Abstract

A medication dispenser in which medication to be dispensed is housed, including a member operable to allow medication access. The dispenser provides a medication alert signal at preselected times in accordance with a desired medication regimen. A medication access signal is provided when medication access is obtained. Data representative of the relative timing between a medication alert signal and a medication access signal is written into a readable memory whereby that data is available to a physician for evaluation. In a preferred embodiment, the data is representative of the time of occurrence of each medication alert signal and medication access signal. The interval between medication alert signals is selectively alterable.
