A pill dispensing cap for a bottle has an inner sleeve with a divider panel and a first base panel rotatable within an outer sleeve having a second base panel. First and second window openings are defined in the first and second base panels. A plate moveable across and within the two sleeves defines a third window opening and a fourth window opening is defined in the divider panel. The plate can be held in an initial position wherein the first and second windows are aligned, whilst the third and fourth windows are not aligned. The outer sleeve is rotatable to a condition wherein the first and second windows are not aligned and the plate can then be slid across to a condition wherein the third and fourth windows are aligned to allow pills in a bottle to enter the inner sleeve.
