Got my latest test results back and, after 2 months on 1800 mg valcyte per day, my hhv-6 titer is the same, 1:320. So, anyone got any ideas? I just lowered my valcyte dose to 1350 per day and I am taking 1000mg inosine and 3000mg lysine (1000 3x a day) also. My titer was originally 1:1280, so it came down quite a bit, but now appears stuck even on high doses of valcyte. On the plus side, everything in my cbc, liver and kidney function tests were normal. My ALT even came down from 41 to 31 while I was on a higher dose of valcyte. So I'm not too concerned about side effects. But I'm not really feeling better either. So, at a loss. This week has absolutely sucked. I was hoping for some more promising news.
