Telbivudine is an antiviral that belongs to a class of drugs known as hepatitis B virus nucleoside reverse transcriptase inhibitors used to treat long-term hepatitis B infection. Telbivudine helps to decrease the amount of hepatitis B virus in your body. Persistent infection can cause liver damage, rarely liver cancer, and liver failure. Telbivudine is not a cure for hepatitis B infection, and it does not prevent the spread of the virus.
