herpes simplex
"Abreva sucks I don't get cold sores myself but my boyfriend does and every time he used abreva like it says when you start to feel it coming on he'd use it but abreva seems to only make it WORSE and puff out. So some lady said to try GLY OXIDE you can find it at any drug store but it works 10000 times better than abreva. Just thought I'd leave this thought with some of you maybe you can try it too."
