dermatitis
"My dermatologist told me to use this right over Fluorouracil creme on my lip to relieve any painful symptoms.  He didn't explain that the Desonate itself could cause painful side effects, like swelling redness, blisters, scaling, burning sensation, cracking of skin, thinning.  It's water insoluble so it's difficult to wash off once it dries.  This med should be used with extreme caution and stopped immediately once these symptoms appear."
