A method of forming a kit containing multiple dissolvable unit dose constructs includes providing at least one muco-adhesive composition comprising a polymer matrix, the polymer matrix comprising a water soluble polymer, an active ingredient and a liquid carrier forming a plurality of dissolvable thin film unit dose constructs by depositing the at least one composition onto a substrate wherein at least two adjacent dissolvable thin film unit dose constructs are formed having a pre-determined different identifiable physical characteristic with respect to the other as a result of the depositing and packaging the plurality of dissolvable thin films in a single package to form a kit.
