Decompensated liver disease: 1mg once daily. Renal impairment (nucleoside-naive): CrCl 30–49mL/min: 0.25mg once daily or 0.5mg every 48hrs; CrCl 10–29mL/min: 0.15mg once daily or 0.5mg every 72hrs; CrCl <10mL/min or on hemodialysis: 0.05mg once daily or 0.5mg every 7 days; (lamivudine-refractory or decompensated liver disease): CrCl 30–49mL/min: 0.5mg once daily or 1mg every 48hrs; CrCl 10–29mL/min: 0.3mg once daily or 1mg every 72hrs; CrCl <10mL/min or on hemodialysis: 0.1mg once daily or 1mg every 7 days.

Severe acute exacerbations of hepatitis B. Patients co-infected with HIV and HBV. Lactic acidosis and hepatomegaly.
Discontinuation of anti-HBV therapy may be associated with severe acute exacerbations of hepatitis B. Closely monitor for several months after stopping treatment; if appropriate, anti-HBV therapy may be warranted. HIV/HBV co-infected patients not receiving highly active antiretroviral therapy (HAART): not recommended. Do HIV antibody testing before initiation. Suspend therapy if lactic acidosis or pronounced hepatotoxicity (eg, hepatomegaly, steatosis) occurs. Renal impairment (see Adults). Liver disease or transplant. Pregnancy. Nursing mothers.
Nucleoside analogue (HBV polymerase inhibitor).
May potentiate or be potentiated by drugs that reduce renal function or compete for active tubular secretion; monitor.
Headache, fatigue, dizziness, nausea; lactic acidosis, severe hepatomegaly with steatosis.
Register pregnant patients exposed to entecavir by calling (800) 258-4263.
