The ring is secured around either a cap or a neck of a conventional medicine or pill bottle. The cap or neck is provided with a pointer. The user then rotates the cap relative to the container to line up the pointer with the appropriate indicia on the ring. In another embodiment the user rotates the O-ring relative to the container or the cap to line up the pointer with the appropriate indicia on the ring. The ring is reusable and fits on conventional containers and caps.
