How effective are Zefix tablets 100 mg from Japan for chronic hepatitis B (lamivudine, Epivir)?
Zefix tablets contain lamivudine, a nucleoside reverse transcriptase inhibitor. It works by blocking reverse transcriptase, an enzyme essential for hepatitis B virus to reproduce in the body. Thus, Zefix tablets suppress the virus growth, decrease the amount of the virus in the blood and decrease the damage to the liver.
