I am not aware of any published info (studies or presentations) by doctors other than Dr Lerner's concerning Valtrex dosing. A summary of Lerner's studies given in
this post.
I believe Lehrner only used Valtrex when EBV was the only active viral infection (as indicated by high antibody titers). If there was CMV or HHV-6 involved, then he used Valcyte. That's because Valtrex does not work for CMV or HHV-6, whereas Valcyte works for all three of these herpesviruses.
Don't want to put you off trying Valcyte, but I don't remember coming across any report on this forum of major benefits arising from Valtrex in the treatment of EBV-associated ME/CFS. (Though if you come across any Valtrex success stories on this forum, please let me know). In Lerner's study, Valtrex appeared to work well; so it is strange that I've not come across any Valtrex success stories
Whereas I've seen quite a few Valcyte success stories (listed in
this post). By success, I mean the patient moves up by at least one level on the ME/CFS scale of:
very severe, severe, moderate, mild, remission as a result of Valcyte.
