Tenofovir drug information for hepatitis B.

Hepatitis B is a virus that is transmitted through the bloodstream to the liver, where it causes inflammation and damage. After infection with hepatitis B, a small number of infected people develop a chronic hepatitis B infection and need treatment to reduce the activity of the virus. Treatment of hepatitis B infection reduces the complications of the infection, including liver damage. One type of treatment for hepatitis B is the use of antiviral drugs such as tenofovir.

Tenofovir belongs to a group of antiretroviral drugs called nucleoside reverse transcriptase inhibitors (NRTIs). Tenofovir for hepatitis B reduces infection and the number of viruses in the body by stopping the growth and multiplication of the hepatitis B virus. A liver specialist usually starts treatment. Treatment for chronic hepatitis B may continue for several years and may include a combination of antiviral drugs.
