herpes simplex, suppression
"So woke up sunday morning with a little blister. Instantly took 4x500mg Valtrex. Unlike the rest of the users on the previous reviews, mine did get bigger and did multiply. It is now Tuesday. It didn't get as big as it would get without the valtrex but still up there and not scabbing yet. So its either I'm not lucky like the rest of the users or they are making it up."
