Valacyclovir
cold sores
"I'm 32 and have had cold sores my whole life. It wasn't until I was about 24 when I decided to see a doctor about them. He gave me some Zovirax which did very little. I was first prescribed Acyclovir about 3 years ago and was amazed how well it worked. The instant that I feel a blister coming on I take Acyclovir and the blisters scab over within a day and begins healing. I remember not wanting to go to school as a kid because of that ugly patch of blisters on my mouth. From beginning to end it used to take 10-14 days for my sores to completely heal. Now it's always less then a week and they are much smaller. Also I've noticed that I don't get them as frequently since I've been taking acyclovir. I always seem to feel moody and irritated on it."
