It may also be that Famvir would work for you while Valtrex does not, if, indeed, all these lesions do turn out to be
herpes. We rarely use
Famvir, but every now and then, we find a patient who does a little better on Famvir than Valtrex.
I personally would not recommend bumping your Valtrex to 2 grams a day. That's a pretty hefty dose, and if 1 gram isn't doing suppression well, then I kind of doubt that 2 grams would do better.
