A blister pack for containing and dispensing unit doses of medication comprises a base sheet (12) and a substantially plan- ar lidding sheet (14). The base sheet has a plurality of blister compartments (16) and a plurality of stepped edges, one stepped edge being adjacent each blister compartment. The lidding sheet (14) is peelably sealed to the base sheet (12) except at extended edge regions forming edge peel tabs (24), and the lidding sheet (14) is scored with lines of weakening (26) about each blister com- partment (16). The stepped edges underlay the unsealed extended edge regions of the lidding sheet, thus providing a finger access to thereby ease the process of grasping a given edge peel tab (24) and ultimately opening a given blister compartment (16). The invention facilitates exposure of a blister compartment (16). Further, the stepped edges of the present invention reduce undesired undulation in the base sheet (12).
