my dr. prescribed timolol drops (yes, they are eye drops for glaucoma, i believe.) for the side of my daughter's head and a gel solution for her lip. in my experience the lip gel didn't stay on well, but the drops we used on the side of her head definitely helped. he told me to be sure to lubricate her lips with vasoline or aquaphor if they looked like they were getting dried out, to prevent ulceration on her lip. he said to wait at least a half an hour after applying timolol to do this.
