Antivirals are to take until hbsag negative hbsab positive, if you stop without those test results all disease comes back worst and the virus can mutate to more aggressive bcp precore or resistant to the antiviral used
Tenofovir is more potent than entecavir if you restart and no resistance, tdf or etv plus peginterferon are more potent and faster to lower hbeag and peginterferon makes hbeag negative lasting even off antiviral after the full course of use and after hbeag neg hbeab pos
why did u stop take entecavir? ur doctor asked to u stop?
