Abstract: A blister package is disclosed that comprises a blister layer having an article receiving blister formed therein for holding medicaments, and a base layer. The blister layer has one or more tearing blisters formed therein and the blister layer is joined to the base layer except in the areas of the article receiving blister and the tearing blisters. The base layer and the blister layer are joined such that opening the blister package to access the medicament requires tearing through one of the tearing blisters and the article receiving blister. The tearing blisters preferably extend from one or more outer edges, which may include the corners, of the blister layer toward said article receiving blister.
