Cold Sores
"This was my third breakout ever! And worst ever. I am 24 yrs old if that helps. Well a small sore began to develop on my bottom lip.  Friday morning my doctor prescribed Valtrex 500mg every 12hrs. I took 1000mg by 10am. Second dose by 8pm.It is now 12:45 pm Saturday and my lip is almost back to its normal size and it is almost completely dry and in scabbing stage. Dont hesitate!"
