Opsite is a brand of wound care products from Smith and Nephew that includes adhesive dressings and medical tape. Opsite dressings provide a moist wound environment while still allowing excess moisture to evaporate, helping prevent skin maceration. They are made from a transparent material that allows you to monitor the conditon of your wound. This flexible material is ideal for use on awkward areas of the body. There is also a grid printed on the film, which acts as a guide if you need to trim the dressing to a different size. Opsite also makes a transparent, skin-safe medical tape to hold non-adhesive bandages or gauze in place.
