i am not sure which, ETV or viread is better for you, but looking at the physical size,
viread and truvada is 300mg, much bigger pill, but low or no resistant,
and everytime i switched prescription, the dr. always want a blood report in 2 months make sure no mutation, and kidney and other organs are still functioning normally. i am the very lucky, rare less than 5% per year that went through hbsag seroconvesion by medication.
