A carrier 56 for a blister pack 94 includes a first panel 82 having an opening 84 for movably receiving a blister of the blister pack, and a second panel 80 having one or more dispensing openings 81 aligned with the first panel opening 84. The blister pack is slidably received between the first and second panels 82. The carrier 56 includes a blocking tab 86 between the panels that is moveable between a blocking position and a dispensing position. When the blocking tab is in its blocking position it prevents movement of the blister in the first panel opening into alignment with a dispensing opening 81, thereby preventing dispensing of the blisters contents through the dispensing opening. When the blocking tab is in the dispensing position, it permits the blister to be moved into alignment with the dispensing opening for dispensing the blisters contents. The blocking tab is connected to a free edge of one of the first and second panels about a fold line, and one of the first and second panels of the blister pack carrier is connected to a panel of a slider.
