What is the most important information I should know about EPIVIR?
EPIVIR can cause serious side effects, including:
- Build-up of an acid in your blood (lactic acidosis).
Lactic acidosis can happen in some people who take EPIVIR. Lactic acidosis is a
serious medical emergency that can cause death. Call your healthcare
provider right away if you get any of the following symptoms that could be
signs of lactic acidosis:
- feel very weak or tired
- unusual (not normal) muscle pain
- trouble breathing
- stomach pain with nausea and vomiting
- feel cold, especially in your arms and legs
- feel dizzy or light-headed
- have a fast or irregular heartbeat
- Serious liver problems can happen in people who
take EPIVIR. In some cases these serious 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 signs or symptoms of liver problems:
- your skin or the white part of your eyes turns yellow (jaundice)
- dark or “tea-colored” urine
- light-colored stools (bowel movements)
- loss of appetite for several days or longer
- pain, aching, or tenderness on the right side of your stomach area
You may be more likely to get lactic acidosis or serious liver problems if you are female, very overweight (obese), or have been taking nucleoside analog medicines for a long time.
- Worsening of hepatitis B virus in people who have
HIV-1 infection. If you have HIV-1 (Human Immunodeficiency Virus type 1)
and hepatitis B virus (HBV) infection, your HBV may get worse (flareup) if you
stop taking EPIVIR. A “flare-up” is when your HBV infection suddenly returns in
a worse way than before. Worsening liver disease can be serious and may lead to
- Do not run out of EPIVIR. Refill your prescription or talk to your healthcare provider before your EPIVIR is all gone.
- Do not stop EPIVIR without first talking to your healthcare provider.
- If you stop taking EPIVIR, your healthcare provider will need to check your health often and do blood tests regularly for several months to check your liver.
- Resistant Hepatitis B Virus (HBV). If you have HIV-1 and hepatitis B, the hepatitis B virus can change (mutate) during your treatment with EPIVIR and become harder to treat (resistant).
- Use with interferon and ribavirin-based regimens. Worsening of liver disease that has caused death has happened in people infected with both HIV-1 and hepatitis C virus who are taking antiretroviral medicines and are also being treated for hepatitis C with interferon with or without ribavirin. If you are taking EPIVIR and interferon with or without ribavirin, tell your healthcare provider if you have any new symptoms.
What is EPIVIR?
EPIVIR is a prescription medicine used together with other antiretroviral medicines to treat Human Immunodeficiency Virus (HIV-1) infection.
EPIVIR tablets and oral solution (used to treat HIV-1 infection) contain a higher dose of the same active ingredient (lamivudine) than is in the medicine EPIVIR-HBV tablets and oral solution (used to treat HBV). If you have both HIV-1 and HBV, you should not use EPIVIR-HBV to treat your infections. The safety and effectiveness of EPIVIR have not been established in children under 3 months of age.
Who should not take EPIVIR?
Do not take EPIVIR if you are allergic to lamivudine or any of the ingredients in EPIVIR. See the end of this Patient Information leaflet for a complete list of ingredients in EPIVIR.
What should I tell my healthcare provider before taking EPIVIR?
Before you take EPIVIR, tell your healthcare provider if you:
- have or have had liver problems, including hepatitis B or C virus infection.
- have kidney problems.
- have diabetes. Each 15-mL dose (150 mg) of EPIVIR oral solution contains 3 grams of sucrose.
- are pregnant or plan to become pregnant. Taking EPIVIR
during pregnancy has not been associated with an increased risk of birth
defects. Talk to your healthcare provider if you are pregnant or plan to become
Pregnancy Registry. There is a pregnancy registry for women who take antiretroviral medicines during pregnancy. The purpose of this registry is to collect information about the health of you and your baby. Talk to your healthcare provider about how you can take part in this registry.
- are breastfeeding or plan to breastfeed. Do not
breastfeed if you take EPIVIR.
- You should not breastfeed if you have HIV-1 because of the risk of passing HIV-1 to your baby. 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-thecounter medicines, vitamins, and herbal supplements.
Some medications interact with EPIVIR. 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 EPIVIR.

How should I take EPIVIR?

- If you take too much EPIVIR, call your healthcare provider or go to the nearest hospital emergency room right away.
What are the possible side effects of EPIVIR?
- EPIVIR can cause serious side effects including:
- See “What is the most important information I should know about EPIVIR?”
- Risk of inflammation of the pancreas (pancreatitis). Children may be at risk for developing pancreatitis during treatment with
EPIVIR if they:
- have taken nucleoside analogue medicines in the past
- have a history of pancreatitis
- have other risk factors for pancreatitis
Call your healthcare provider right away if your child develops signs and symptoms of pancreatitis including severe upper stomach-area pain, with or without nausea and vomiting. Your healthcare provider may tell you to stop giving EPIVIR to your child if their symptoms and blood test results show that your child may have pancreatitis.
- Changes in your immune system (Immune Reconstitution Syndrome) can happen when you start taking HIV-1 medicines. Your immune system may get stronger and begin to fight infections that have been hidden in your body for a long time. Tell your healthcare provider right away if you start having new symptoms after you start taking EPIVIR.
- Changes in body fat can happen in people who take HIV-1 medicines. These changes may include an increased amount of fat in the upper back and neck (“buffalo hump”), breast, and around the middle of your body (trunk). Loss of fat from the legs, arms, and face may also happen. The exact cause and long-term health effects of these conditions are not known.
