herpes simplex
"I had run out of Zovirax cream and was waiting a day or so on a refill from my dr. I was having a bad breakout with 4 on my lips, ugh!! I read a lot of reviews for Abreva and wish I went with my guy and not buy this crap (for $25 to boot)! Doesn't work whatsoever. One review said that they actually woke up the next morning with another sore - and so did I! So upset with this product I may write a letter to them demanding a refund."
