herpes simplex, suppression
"I was having fever blisters come up about every 6 weeks. I started taking valcyclovir and it would really help speed up the healing process, but I was still getting them about every 6 weeks. The V.A. started me on acyclovir and my outbreaks have been tremendously lessened. When there is an outbreak, I usually only need to take it for 2 days."
