My outpatient clinic used these wipes on my skin around my PICC line entrance wound and my skin broke out in blisters almost immediately, causing my wound to bleed. Two days later they tried to use them again with same results. Searching the Convatec websites was absolutely no use as they do not list the active ingredients anywhere - other sites gave the base of alcohol but nothing else. Very irresponsible for a medical supplies manufacturer not to give all ingredients especially when suggested uses for open wounds!! I would want to know list of ingredients prior to use~!!
