A novel child resistant blister foil package for use with oblong medicaments, such as caplets, is disclosed comprising a base layer and a rigid, substantially rectangular blister layer composed of low-extensible film joined to the base layer. The blister layer of this package has an oblong, longitudinally oriented blister formed on one end thereof and a longitudinally directed tear slit disposed through the opposing edge thereof. Tear tabs are thus provided between the blister and the slitted edge which permit the package to be torn open through the entire length of the oblong blister. The preferred package exhibits a tear propagation resistance, in accordance with ASTM method D1938, which, unlike flexible pouch packages, is substantially continuous during the opening of the package.
