Mepilex Ag - Antimicrobial Soft silicone Foam Dressing absorbs exudate and maintains a healthy, moist wound environment. Mepilex Ag (silver dressing) begins neutralizing wound related pathogens within 30 minutes of application to the wound site. This comfortable silver dressing is easy to use and can effectively kill bacteria for up to 7 days. Mepilex Ag may also also help to eliminate odor, reduce the risk of maceration, and can be removed without damaging the fragile skin surrounding the wound.
