Vemlidy (tenofovir alafenamide, TAF) is a prescription medication approved to treat chronic (long-lasting) hepatitis B virus (HBV) in combination with other antiviral drugs in adults with stable liver disease. Viread (tenofovir disoproxil fumarate, TDF) is also used to treat chronic hepatitis B, but is also approved to treat human immunodeficiency virus (HIV).

Vemlidy is a prodrug of tenofovir that has been shown to have similar antiviral effectiveness to Viread, but improved kidney and bone safety based on laboratory results.
