Herpes Simplex, Suppression
"If you take just one pill when you begin to feel a tingle, you won&#039;t actually get a cold sore/fever blister. It&#039;s seriously amazing! I wish I had known about this sooner. I will get a cold sore if I travel a lot or if I have any minor trauma on or around my nose/mouth. One pill when I feel it coming on stops them from forming, but you have to catch it before the blister develops. Keep taking the pill until the tingling goes away. I&#039;ve never had to take more than 1 pill per occurance."
