About Zeffix
Uses and Benefits of Zeffix
Zeffix is indicated for the treatment of chronic hepatitis B virus (HBV) when the disease is progressing, and the liver is inflamed. It helps slow the progression of HBV but does not cure the infection.
It is unknown if Zeffix is safe and effective in:
- People with severe liver damage (decompensated liver disease)

Zeffix does not prevent the spread of HBV. Avoid activities that can transmit the virus, such as unprotected sex, sharing needles, or exposing others to your blood.
