The medicinal patch for delivering a pharmaceutically effective ingredient by contact with skin has a backing layer (1), an effective-ingredient containing adherent layer (2) on the backing layer and a release layer (4) applied over the adherent layer (2). To eliminate a dirt ring deposited when the medicinal patch is finally removed from the skin, a plastic foil or film (3) is provided on an outer peripheral or edge region of the skin-contacting surface of the adherent matrix layer (2). The plastic foil or film, which does not adhere to the skin, can be made of polyester, hydrocarbon polymers or silicone polymers and preferably has a thickness of 15 to 75 .mu.m with a width of 1 to 3 mm. Methods of making medicinal patches of this sort are described.
