I don't think the decision can be made only with hbv DNA alone, also need to look at alt/ast, hbeag, anti-hbeag, possibly also factor in age, lipid panel, kidney functions, etc, along with frequent monitoring, it also has been reported that high chance when stop anti-viral may cause strong flare. Keep in mind that this hbv cause inflammation infection to liver, repeatedly self healing and then re inflammation may cause scarring could lead to irreversible cirrhosis, decompensated liver or worst, end stage liver cancer, again, it is just my personal opinion, I would not take the chance if this pill has no other major side effect. I am not a doctor or in any medical field.
very wrong advice and many many risks, among them resistance and resistance to tdf can be a big problem if you have already mutations to weaken etv response which translates no rescue therapy.this is the worst scenario together with liver cancer.taking month in and out can be more damaging than no therapy.take it every day and by about 17 years you could be cured even with antivirals
