What VEMLIDY is used for
VEMLIDY is used for the treatment of chronic (long-lasting) hepatitis B virus (HBV) in adults.
VEMLIDY contains the active substance tenofovir alafenamide. This active substance is an antiviral medicine, known as a nucleotide reverse transcriptase inhibitor (NtRTI).
How VEMLIDY works in the treatment of Chronic Hepatitis B (CHB)
VEMLIDY works by interfering with the normal working of an enzyme (DNA polymerase) that is essential for the HBV to reproduce itself. VEMLIDY may help lower the amount of hepatitis B virus in your body by lowering the ability of the virus to multiply and infect new liver cells and can improve the inflammation and scar tissue caused by the hepatitis B virus in your liver. Lowering the amount of virus in your body may reduce the chance of developing cirrhosis, liver failure and liver cancer.
We do not know how long VEMLIDY may help treat your hepatitis. Sometimes viruses change in your body and medicines no longer work. This is called drug resistance.
It is not known if VEMLIDY is safe and effective for treatment of HBV in children or adolescents under 18 years of age.
