The present invention relates to a disposable article to prevent the misuse of a transdermal dosage form (Fig. 1 (a)). The article is comprised of an outer layer (1) having an inner layer-facing side and an opposite side; an inner layer (3) having an outer layer-facing side and an opposite side, the inner layer (3) joined to the outer layer (1) to form one or more closed material reservoir (2) between the outer layer-facing side of the inner layer (2) and the inner layer-facing side of the outer layer (1); and adhesive (4) covering a first portion of the opposite side of the inner layer (3), wherein the adhesive (4) is a heat activated adhesive that changes color and/or is activated when the article is subjected to elevated temperatures, thereby sealing the transdermal dosage form within the article.
