Tenofovir is used to treat long-term hepatitis B infection. It is called an antiviral medicine. Tenofovir works by stopping the hepatitis B virus from multiplying and in this way reduces the amount of the virus in your body. It is used for the treatment of chronic hepatitis B and HIV infection and for pregnant women who have chronic hepatitis B.
Tenofovir is not a cure for hepatitis B. It does not prevent the spread of the virus to others through sexual contact or blood or body fluid contamination, such as sharing used needles. Read more about chronic hepatitis B.
In New Zealand tenofovir is available as tablets (245 mg).
Tenofovir is also available in combination with other medicines to control HIV, eg, Truvada (tenofovir + emtricitabine) and Atripla (tenofovir + emtricitabine + efavirenz).
