Uses
Telbivudine is used to treat long-term hepatitis B infection. Hepatitis B is an infection of the liver caused by the hepatitis B virus. Long-term infection can cause liver damage, rarely liver cancer, and liver failure. Telbivudine helps to decrease the amount of hepatitis B virus in your body. It is an antiviral that belongs to a class of drugs known as hepatitis B virus nucleoside reverse transcriptase inhibitors.Telbivudine is not a cure for hepatitis B infection, and it does not prevent the spread of the virus to others through sexual contact or blood contamination (such as sharing used needles).
