I have tried Imunovir from Gold Pharma (it was very difficult to receive it- shipping was a nightmare) Also the writing on the box was not english- it may have been greek or israeli)
Then for several months I have been on Inosine. For patients that can't afford Imunovir, Dr Klimas suggests Inosine, she says it's similar. When my canadian doctor was ready to prescribe Imunovir, he asked I stopped Inosine for 2 weeks. He tested my uric acid which was very high- a sign that it is doing something- do not worry about increased uric acid, Nancy doesn't even test it. It is expected to go high.
During the 2 weeks wash out period I developed fibro-like pain something I never had before. That was "interesting".
Then I started Imunovir and the fibro-like pain subsided. It cost me 225$ for a box of 100 tablets, and didn't help any of my symptoms.
I cannot compare my NK cell function from before to after because of difference in lab testing (Nancy's lab vs Quest). I think my NK cell function improved, however, I stopped it (it can get rough at the end of the week of 2 tabs 3 times a day) - and putting all my money on Rituximab.
If you want to try, I would suggest Inosine I bought it at iherb.com. If you are canadian you may have trouble getting it through the border and it would be best to pick it up across. It is not sold in Canada.
