The present disclosure relates to a medical dressing patch which is used to simultaneously protect and treat an injury to a skin such as burns, wounds, and traumas, and more particularly, to a medical dressing patch including: a release paper; and an adhesive sheet which is fixed to an upper portion of the release paper and attached to a skin, in which the release paper includes a fixing release paper, and a separation release paper which is fixed to the fixing release paper through a cut-out portion and a connecting portion formed on the fixing release paper, and positioned such that a predetermined region of the separation release paper overlaps a lower surface of the adhesive sheet so that the separation release paper is separated together with the adhesive sheet when the adhesive sheet is separated from the fixing release paper.
