Cold Sores
"I don&#039;t write too many reviews but I wanted to let you know that this medicine really works. I woke up with tingling on my lip and knew exactly what it was, then 4 hours later another one appeared.  I immediately started putting Zovirax on my cold sores every 2 hours.  I woke up the next morning to find another one starting.  I knew that I couldn&#039;t handle 3 of these hideous things on my face and I had heard from a drug rep that Valtrex really worked.  But, she wasn&#039;t sure if it worked AFTER they had been present for a day or two.  I called my doctor and she prescribed Valtrex -36 hrs after they started.  I can honestly say that it worked.  In 3 days, there was nothing but a simple little red mark on my lips."
