TAP for Patient Information, including important warnings on the build-up of lactic acid in your blood, severe liver problems, and worsening of Hepatitis B infection.

PATIENT INFORMATION

Read this Patient Information before you start taking VEMLIDY and each time you get a refill. There may be new information. This information does not take the place of talking with your healthcare provider about your medical condition or treatment.

What is the most important information I should know about VEMLIDY?

VEMLIDY can cause serious side effects, including:

  • Build-up of lactic acid in your blood (lactic acidosis). Lactic acidosis may happen in some people who take VEMLIDY or similar medicines. Lactic acidosis is a serious medical emergency that can lead to death.

    Lactic acidosis can be hard to identify early, because the symptoms could seem like symptoms of other health problems. Call your healthcare provider right away if you get any of the following symptoms which could be signs of lactic acidosis:

  • feel very weak or tired
  • have unusual (not normal) muscle pain
  • have trouble breathing
  • have stomach pain with nausea or vomiting
  • feel cold, especially in your arms and legs
  • feel dizzy or lightheaded
  • have a fast or irregular heartbeat
  • Severe liver problems. Severe liver problems may happen in people who take VEMLIDY. In some cases, these liver problems can lead to death. Your liver may become large (hepatomegaly) and you may develop fat in your liver (steatosis).
  • Call your healthcare provider right away if you get any of the following symptoms of liver problems:

  • your skin or the white part of your eyes turns yellow (jaundice)
  • dark “tea-colored” urine
  • light-colored bowel movements (stools)
  • loss of appetite
  • nausea
  • pain, aching, or tenderness in the right side of your stomach area

You may be more likely to get lactic acidosis or severe liver problems if you are female, very overweight (obese), or have been taking VEMLIDY or a similar medicine for a long time.

  • Worsening of hepatitis B infection. Your hepatitis B (HBV) infection may become worse (flare-up) if you take VEMLIDY and then stop taking it. A “flare-up” is when your HBV infection suddenly returns in a worse way than before.
  • Do not run out of VEMLIDY. Refill your prescription or talk to your healthcare provider before your VEMLIDY is all gone.
  • Do not stop taking VEMLIDY without first talking to your healthcare provider.
  • If you stop taking VEMLIDY, your healthcare provider will need to check your health often and do blood tests regularly for several months to check your HBV infection. Tell your healthcare provider about any new or unusual symptoms you may have after you stop taking VEMLIDY.

For more information about side effects, see the section “What are the possible side effects of VEMLIDY?”

What is VEMLIDY?

VEMLIDY is a prescription medicine used to treat chronic (long-lasting) hepatitis B virus (HBV) in adults with stable (compensated) liver disease.

  • VEMLIDY may lower the amount of HBV in your body.
  • VEMLIDY may improve the condition of your liver.

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

What should I tell my healthcare provider before taking VEMLIDY?
Before you take VEMLIDY, tell your healthcare provider about all of your medical conditions, including if you:

  • have HIV-1 infection. Your healthcare provider may test you for HIV infection before starting VEMLIDY. If you have HIV and take VEMLIDY, the HIV virus may develop resistance and become harder to treat.
  • have end stage renal disease (ESRD)
  • are pregnant or plan to become pregnant. It is not known if VEMLIDY will harm your unborn baby. Tell your healthcare provider if you become pregnant during treatment with VEMLIDY.
    Pregnancy Registry: There is a pregnancy registry for women who take antiviral medicines during pregnancy. The purpose of this registry is to collect information about the health of you and your baby. Talk with your healthcare provider about how you can take part in this registry.
  • are breastfeeding or plan to breastfeed. It is not known if VEMLIDY passes into your breast milk. Talk with your healthcare provider about the best way to feed your baby.

Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements.

Some medicines may affect how VEMLIDY works.

  • Keep a list of your medicines and show it to your healthcare provider and pharmacist when you get a new medicine. You can ask your healthcare provider or pharmacist for a list of medicines that interact with VEMLIDY.
  • Do not start a new medicine without telling your healthcare provider. Your healthcare provider can tell you if it is safe to take VEMLIDY with other medicines.

How should I take VEMLIDY?

  • Take VEMLIDY exactly as your healthcare provider tells you to take it.
  • Take VEMLIDY 1 time each day.

  • Do not change your dose or stop taking VEMLIDY without first talking with your healthcare provider. Stay under a healthcare provider’s care when taking VEMLIDY.
  • Do not miss a dose of VEMLIDY.
  • If you take too much VEMLIDY, call your healthcare provider or go to the nearest hospital emergency room right away.
  • When your VEMLIDY supply starts to run low, get more from your healthcare provider or pharmacy. This is very important because your HBV infection may get worse (flare-up) if you stop taking VEMLIDY.

VEMLIDY may cause serious side effects, including:

  • See “What is the most important information I should know about VEMLIDY?”
