What is tenofovir?

Tenofovir is a prescription drug. It comes as an oral tablet and oral powder.

Tenofovir oral tablet is available as a generic drug and as the brand-name drugs Viread and Vemlidy.

This drug is used as part of a combination therapy. That means you’ll likely take this drug in combination with other drugs to treat your condition.

Why it’s used

Tenofovir is used to treat:

  • HIV infection, in combination with other antiretroviral drugs. This drug doesn’t eliminate the virus entirely, but it helps to control it.
  • chronic hepatitis B virus infection.

How it works

Tenofovir belongs to a class of drugs called nucleoside reverse transcriptase inhibitors (NRTIs). It’s also a hepatitis B virus reverse transcriptase inhibitor (RTI). A class of drugs is a group of medications that work in a similar way. These drugs are often used to treat similar conditions.

Tenofovir works in the same way for both HIV infection and chronic hepatitis B virus infections. It blocks the effectiveness of reverse transcriptase, an enzyme required for each virus to make copies of itself. Blocking reverse transcriptase can reduce the amount of the virus in your blood.

Tenofovir can also increase CD4 cell count. CD4 cells are white blood cells that fight infection.
