That's a good set of questions,

Imunovir
Imunovir (inosine pranobex) is an immunomodulatory and antiviral drug used by ME/CFS specialists such as Dr Cheney, Dr Klimas and Dr De Meirleir. Dr Chia often uses Imunovir in conjunction with oxymatrine.

Imunovir is a combination of three components: inosine, acetamidobenzoic acid, and dimethylaminoisopropanol. (These components are chemically bonded together as a molecular complex). However, Dr De Meirleir and Dr Cheney feel that taking inosine alone instead of Imunovir provides equally good results. Inosine is an inexpensive dietary supplement available without prescription, so this makes it cheaper and easier to take inosine rather than the drug Imunovir.
Dr Cheney’s "pulsing" protocol for Imunovir / inosine:
"Week one: take 6 tablets a day, Monday through Friday, and none on the weekend. Week two: take 2 tablets a day, Monday through Friday, and none on the weekend. Repeat this cycle. But do not treat every month. Do two months on and then one month off of this "pulsing" dose. This medicine works best when you do not treat regularly. If you treat continuously at the same dose, it stops working. It is an immune modulator, and Dr. Cheney suspects all immuno-modulators are like this. If taken continuously they stop working."
Though even with pulsing, some patients report that the effects of Imunovir / inosine diminish with long-term use.
