Tenofovir is utilized alongside other HIV medications to manage HIV infection effectively. It works by reducing the quantity of HIV in your body, thereby enhancing your immune system’s functionality. This reduces the likelihood of HIV-related complications, such as new infections and cancer, while also enhancing your overall quality of life. Tenofovir falls into the category of drugs known as nucleotide reverse transcriptase inhibitors (NRTIs).
Tenofovir is also employed in the treatment of a specific type of liver infection known as chronic hepatitis B infection. In this context, it functions by reducing the concentration of the hepatitis B virus in your body, effectively impeding its growth.
