Chronic hepatitis B virus (HBV) infection is currently incur-able. Long-term treatment with potent and safe nucleos(t)ide analogues  (NAs)  can  reduce hepatocellular carcinoma  (HCC),  cirrhotic complications,  and liver-related mortality through substantial viral suppression.1 However, long-term therapy  raises several  crucial  issues  with  pros  and  cons.  Because hepatitis B surface antigen (HBsAg) seroclearance or functional cure is not easily achievable, a finite therapy may provide an opportunity to facilitate HBsAg seroclearance by the  rejuvenation  of  exhausted  immune  cells.  However,  the  virological relapse (VR) or surge of alanine aminotransferase (ALT) levels may increase the risk for adverse outcomes (e.g., decompensation, fibrosis progression, HCC, or liver-related mortality) before HBsAg seroclearance, which are the safety concerns  of  finite  therapy.  Little  is  known about  whether repeated therapeutic interruption will increase the chance of drug resistance, whereas the reduction of renal function and bone mineral density are the safety issues of infinite therapy. Lastly,  the  practice  of  “to  stop”  or  “to  continue”  therapy  should also consider the accessibility and affordability of thehealth  care  system.  Patients  who  stop  therapy  need  to  be  monitored  closely  with  frequent  virological  and  biochemical tests in the first year, especially if they experience a VR or clinical  (biochemical)  relapse  (CR)  (Table  1).  About  40%  of patients who stop NA therapy eventually receive retreatment.2 The cost-effective analysis should thus be performed on the basis of individual regions.
