Patient Education

Adefovir


Adefovir is used to treat chronic (long-term) hepatitis B infection (swelling of the liver caused by a virus) in adults and children 12 years of age and older. Adefovir is in a class of medications called nucleotide analogs. It works by decreasing the amount of hepatitis B virus (HBV) in the body. Adefovir will not cure hepatitis B and may not prevent complications of chronic hepatitis B such as cirrhosis of the liver or liver cancer. Adefovir may not prevent the spread of hepatitis B to other people.
