Abstract
The invention provides a device that cautions the user of medication, for example, by visual change and/or surface contour change of a part of a medicine container, that a preset time since an event, such as since the last prior use or application of the medication, has not transpired. The medicine container cover or an indicating element of the container or cover changes visually or dimensionally to signal the user that it is not advisable to administer the next dose of the medication. The device shuts itself down upon changing to a permissive configuration, and requires no power input until it is again activated by accessing the container.
