A medication-taking support device that has no possibility of a pill case being left outside the medication-taking support device even if the pill case ejected outside a casing is not received by a user is provided. The medication-taking support device includes a cassette (25) that stores medicine-containing pill cases in such a manner that the pill cases are stacked on top of one another, a push-out mechanism (30) that pushes out the pill case on a lowermost tier in the cassette (25) by a predetermined dimension, and a pull-back mechanism (32) that pulls back the pill case remaining on the lowermost tier without being extracted from the cassette (25) into the cassette (25).
