Compare Vemlidy vs. Epivir

Head-to-head comparisons of medication uses, side effects, ratings, and more.

Treats hepatitis B virus (HBV) infections.

Vemlidy (tenofovir alafenamide) decreases liver damage from hepatitis B virus (HBV) and has minimal side effects, but doesn't cure the infection.

Works with other medicines to treat HIV infection or chronic hepatitis B.

Epivir (lamivudine) is a first-choice and commonly used medicine to take together with other HIV medications to treat HIV. It is also an alternative option for treating chronic hepatitis B.

  • Vemlidy (tenofovir alafenamide) is a first-choice medicine to treat hepatitis B.
  • Conveniently taken once daily.
  • Compared to Truvada and Viread (tenofovir disoproxil fumarate), Vemlidy (tenofovir alafenamide) is safer for your kidneys and bones.
  • Epivir (lamivudine) can be used with many other HIV options to create a combination that's right for you.
  • Has very minimal interactions with other medications.
  • Available in tablet and liquid form.
  • Can be take once or twice a day. Also available in different combination pills so you don't have to take as many pills per day.
  • Available in cheaper generic form.
  • Might not be the best choice for people with severe kidney damage.
  • There's not enough evidence to show that Vemlidy (tenofovir alafenamide) can be used safely in children ages 18 or younger.
  • Cannot take Epivir (lamivudine) by itself to treat HIV.
  • Might need to change dosage based on how well your kidneys function.
  • It is recommended to use other options to treat chronic hepatitis B before choosing Epivir (lamivudine) due to drug resistance.
  • You'll have to be tested for both HIV and hepatitis B, since the dose to treat hepatitis B is lower than the dose for HIV. If you have the lower dose, HIV can be harder to treat if you also have hepatitis B.
  • The liquid version of Epivir (lamivudine) has sugar, so if you have diabetes, your blood sugar levels might change.
