Dosage Guide

Quick Answer

The standard dose of Entecavir in antiviral-inexperienced patients is 0.5mg once daily. In lamivudine-experienced or decompensated liver disease it is 1mg once daily. It must be taken on an EMPTY STOMACH — food significantly reduces absorption. Dose reduction is required in renal impairment. NEVER stop without a specialist.

Regular monitoring of renal function (creatinine/eGFR) is necessary.

Take 2 hours before or 2 hours after food
Food (especially a high-fat meal) significantly reduces entecavir absorption
Maintain consistent timing — same time every day

Long-term adherence is critical — missing doses can develop viral resistance and cause treatment failure.
