Famciclovir
cold sores
"I have had cold sores since I can remember. they've always been hugely traumatic for me and really mess with my self esteem not to mention everyone on here would know they aren't pleasant physically!



I've always tried lysine which seemed to help but now that I've discovered famiclovr I realize they were doing nothing. 



I've taken the three tablets on three occasions now where they prevented a cold sore from coming out altogether! 



There have been two occasions where I took the tablets when I felt a blister and the blister got bigger however the very next day seems to be nearly gone. 



Basically, if the cold sore is too powerful/you're too late to take the medicine it still reduces the healing time from 2 weeks to 4 days! Amazing drug."
