cold sores
"I get cold sores about every other month. I went to my Dermatologist and she gave a prescription for Sitavig. It sticks on your gum which is weird and takes getting used to, but she told me it is supposed to make you have fewer outbreaks. Sure enough, I went 5 months before my next one. When I saw her next I did complain that it took long time to dissolve. She said that was part of what made it work so well. Not sure how, but I will never go back to using my valtrex."
