Valacyclovir
"I was introduced to Valtrex for HSV2 suppression in mid 2000 after surgery to my groin.  The outbreak was the worst I had experienced in the 20 years that I'd suffered.  The daily 500mg treatment worked immediately in clearing up the outbreak, and much more importantly, I've been OUTBREK FREE since then to the posting of this note, July 2011.  I'm a believer.  Now the VA has changed my prescription of Valtrex, once a day, to Acyclovir, 400mg twice a day.  I'm fervently hoping the suppressive qualities I've enjoyed with Valtrex remain...keeping my fingers crossed."
