Herpes Simplex
"I was surprised to see quite a few negative reviews of Abreva.   It works great for me. As soon as I noticed the itching I put it on right away and as often as I can throughout the day. There&#039;ve been some times where you can barely notice there&#039;s anything on my lip.  It heals up quickly and numbs the pain.   I remember the old days when it would take two weeks or more to fully heal, and it would be a big, awful sore on your lip.  I don&#039;t get cold sores that often, but I always have Abreva on hand.   One thing I did notice is that when I had a tube for a long time that was six months or more until the expiration date it didn&#039;t work as well as a new tube.   It&#039;s expensive, but I think it&#039;s totally worth it!"
