What is Vemlidy?

Vemlidy is a prescription antiviral medicine that prevents the hepatitis B virus from multiplying in your body.

Vemlidy is used to treat patients with chronic hepatitis B infection in adults with compensated liver disease.

Vemlidy may lower the amount of HBV in your body and may improve the condition of your liver.

It is not known if Vemlidy is safe and effective in children under 18 years of age.

Warnings

If you have hepatitis B, it may become active or get worse after you stop using Vemlidy. You may need frequent liver function tests for several months.

Do not stop using Vemlidy without first talking to your doctor. If you have ever had hepatitis B, stopping treatment with tenofovir can cause acute exacerbations of hepatitis B. You will need frequent blood tests to check your liver function.

Vemlidy is not recommended in patients with end stage renal disease.

Tenofovir alafenamide (Vemlidy) is used to treat patients with chronic hepatitis B. Tenofovir disoproxil (Viread) is used to treat HIV-1 infection and chronic hepatitis B.

To make sure Vemlidy is safe for you, tell your doctor if you have ever had:

You may develop lactic acidosis, a dangerous build-up of lactic acid in your blood. Ask your doctor about your risk.

Tell your doctor if you are pregnant, and use your medications properly to control your infection.

It may not be safe to breastfeed while using Vemlidy. Ask your doctor about any risk.
