(I was taking lamivudine, hepsera initially around 2004 and was told the hbv mutated only in a few months, then switched to viread, and the virus was quickly under control in a few months, the dr. saw a good
success rate, and asked me to try travada)
here is my opinion, find out what cause high alt first before stopping the pill.
and make sure only hbsab is positive while hbv dna and hbsag are both negative. It seems like only good friend here is hb surface anti body.
