Is there any problem if im not taking etv 0,5 at same hour? I mean, sometimes i took it 1-2 h earlier, other times 1-3 h later than usual.
No, there should be no concerns. Just continue with your regular dosage. Some patients take 2x0.5mg per day of Entecavir for their treatment (in case of previous experience with Lamivudine).
I am not a doctor.
