Silver sulfadiazine
"Was treated for precancerous cells on my chest with Picato, a topical chemotherapy cream that is used for two days. I almost immediately developed a severe reaction where my skin blistered and then began to slide off leaving huge oozing wounds. I cannot describe the pain which, in turn, caused horrible headaches and nausea. Because of the location of the injury I was unable to even wear a shirt. After 3 1/2 days of misery I applied silvadeen and had relief right away. I could actually breathe again. Since I just did this I am not sure of the outcome but for now I am very thankful."
