VIREAD®
(tenofovir disoproxil fumarate) is a type
of medicine called a nucleotide analog reverse
transcriptase and hepatitis B virus (HBV)
polymerase inhibitor (NRTI). VIREAD is used
to treat chronic hepatitis B (an infection
with HBV) in adults age 18 years and older.
VIREAD works by interfering with the normal
working of an enzyme (HBV DNA polymerase)
that is essential for the HBV to reproduce
itself. VIREAD 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.
