Entecavir should be administered on an empty stomach (at least 2 hours after a meal and 2 hours before the next meal).
Recommended Dosage: The recommended dose of entecavir for chronic hepatitis B virus infection in nucleoside-treatment-naive adults and adolescents 16 years of age and older is 0.5mg once daily.
The recommended dose of entecavir in adults and adolescents (≥16 years of age) with a history of hepatitis B viremia while receiving lamivudine or known lamivudine resistance mutations is 1mg once daily.
Renal Impairment: In subjects with renal impairment, the apparent oral clearance of entecavir decreased as creatinine clearance decreased. Dosage adjustment is recommended for patients with creatinine clearance <50ml/min, including patients on hemodialysis or continuous ambulatory peritoneal dialysis (CAPD), as shown in Table 1.
