Allevyn* Ag Non-Adhesive is an absorbent antimicrobial three layer dressing consisting of an SSD (Silver Sulfadiazine) containing absorbent hydrocellular pad sandwiched between a perforated non adherent wound contact layer and a waterproof outer film. The dressing provides an effective barrier to microbial contamination protecting the wound from invasive pathogenic micro-organisms, thus assisting faster healing. SSD is effective against micro-organisms present in the dressing and in the wound. In the presence of exudate the dressing will help maintain a moist wound environment.
