My daughter (11) suffers from cold sores on her lips. She got one the other day, and I started letting her use Abreva for the first time. It seems to be slowing the growth of the sore (keeping it from travelling up her lip) but doesn't seem to be cutting the duration time of the healing. Although it does look much less "angry" than they usually do. Do any of you have experience with this medication? Do you feel it helps you? Is there any other meds you could recommend?
