herpes simplex, suppression
"I've been taking Valtrex for almost 18 years for suppression of cold sores.  i would get them all the time before Valtrex, probably like 7 a year.  I started with a daily dose of 500mg and would get one every now and again.  I up it to 1 gram and haven't had an outbreak in more than 10 years!  Now, I'm back down to 500mg and if i feel an olutbreak coming on I'll put a little zoviraz on it with some DMSO after and the sore goes away within 30 minutes.  The combination works well.  Hope this helps."
