Hilfovir Tablet is an antiviral medicine. It is prescribed for human immunodeficiency virus (HIV) infection. It slows the progress of HIV infection, but it is not a cure. HIV destroys cells in the body, called CD4 T cells. If left untreated, the HIV infection weakens your immune system so that your body cannot defend itself against bacteria, viruses and other germs. Tenofovir slows down the progress of HIV infection by reducing the amount of virus in your body. It does this by stopping the virus from copying (replicating) itself.
It belongs to a group of antiretroviral medicines known as nucleoside reverse transcriptase inhibitors (NRTIs). Taking three or more antiretroviral medicines at the same time is more effective than taking one alone. Taking a combination of different medicines also reduces the risk that the virus will become resistant to any individual medicine. Some brands of tenofovir tablet contain one or more other antiretroviral medicine (see the list in the table above) – these combination brands help to reduce the total number of tablets you need to take each day. Not all of the information in this leaflet applies to the combination brands, so please refer to the manufacturer’s printed information leaflet from inside the pack for full details. It is vital to take your antiretroviral medicines exactly as prescribed to maintain success and to help to prevent the virus from becoming resistant to the medicines.
Tenofovir is also prescribed for another viral infection – see the separate medicine leaflet called Tenofovir for hepatitis B infection.
The most common side-effects of t are feeling sick (nausea), feeling dizzy, diarrhoea, and skin rash.
