Can tenofovir disoproxil fumarate (Viread) be taken long-term?

Tenofovir disoproxil fumarate (Viread) is an antiretroviral drug commonly used to treat HIV (HIV) and hepatitis B virus (HBV) infections. The duration of treatment with this drug will depend on the severity of the viral infection. Patients need to undergo regular blood tests as directed by their doctor to check the viral load in the body. The duration of tenofovir disoproxil fumarate use will be appropriately determined by your doctor and, in rare cases, lifelong treatment may be required. If patients take the drug and then stop taking it, they may experience a flare-up and worsening of the condition. Patients should have close clinical and laboratory follow-up for at least several months after stopping treatment and may need to resume antiviral treatment if appropriate.
