Tenofovir is used with other medications to help control your HIV infection, thereby improving your quality of life. It helps to decrease the amount of HIV in your body so your immune system can work better. It also lowers your risk of getting HIV disease complications (such as new infections, cancer). Tenofovir belongs to a class of drugs known as nucleotide reverse transcriptase inhibitors (NRTIs). Tenofovir is not a cure for HIV and it does not prevent the spread of HIV to others through sexual contact or blood contamination (such as sharing used needles). Tenofovir is also used to treat a certain type of liver infection called chronic hepatitis B infection. It helps to decrease the amount of hepatitis B virus in your body by interfering with virus growth.
