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

TRIZIVIR can cause serious side effects, including:

  • Serious allergic reactions (hypersensitivity reaction) that can cause death have happened with TRIZIVIR and other abacavir-containing products. Your risk of this allergic reaction is much higher if you have a gene variation called HLA-B*5701. Your healthcare provider can determine with a blood test if you have this gene variation.
    If you get a symptom from 2 or more of the following groups while taking TRIZIVIR, call your healthcare provider right away to find out if you should stop taking TRIZIVIR.

Group 1 Fever
Group 2 Rash
Group 3 Nausea, vomiting, diarrhea, abdominal (stomach area) pain
Group 4 Generally ill feeling, extreme tiredness, or achiness
Group 5 Shortness of breath, cough, sore throat

A list of these symptoms is on the Warning Card your pharmacist gives you. Carry this Warning Card with you at all times.

If you stop TRIZIVIR because of an allergic reaction, never take TRIZIVIR (abacavir, lamivudine and zidovudine) or any other abacavir-containing medicine (EPZICOM® , TRIUMEQ®, or ZIAGEN®) again.

  • If you take TRIZIVIR or any other abacavir-containing medicine again after you have had an allergic reaction, within hours you may get life-threatening symptoms that may include very low blood pressure or death.
  • If you stop TRIZIVIR for any other reason, even for a few days, and you are not allergic to TRIZIVIR, talk with your healthcare provider before taking it again. Taking TRIZIVIR again can cause a serious allergic or life-threatening reaction, even if you never had an allergic reaction to it before.

If your healthcare provider tells you that you can take TRIZIVIR again, start taking it when you are around medical help or people who can call a healthcare provider if you need one.

  • Blood problems. Zidovudine (RETROVIR®), one of the medicines in TRIZIVIR, can cause serious blood cell problems. These include reduced numbers of white blood cells (neutropenia) and extremely reduced numbers of red blood cells (anemia). These blood cell problems are especially likely to happen in people with advanced human immunodeficiency virus type 1 (HIV-1) disease or AIDS. Your healthcare provider should check your blood cell counts regularly during treatment with TRIZIVIR.
  • Muscle pain or weakness (myopathy) can happen during treatment with TRIZIVIR. Zidovudine (RETROVIR®), one of the medicines in TRIZIVIR, can cause muscle pain or weakness when used for a long time.
  • Build-up of acid in your blood (lactic acidosis). Lactic acidosis can happen in some people who take TRIZIVIR. 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
    • feel cold, especially in your arms and legs
    • unusual (not normal) muscle pain
    • feel dizzy or light-headed
    • trouble breathing
    • have a fast or irregular heartbeat
    • stomach pain with nausea and vomiting
  • Serious liver problems can happen in people who take TRIZIVIR. 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)
    • loss of appetite for several days or longer
    • nausea
    • dark or “tea-colored” urine
    • pain, aching, or tenderness on the right side of your stomach area
    • light colored stools (bowel movements)

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 analogue medicines for a long time.

  • Worsening of hepatitis B virus in people who have HIV-1 infection. If you have HIV-1 and hepatitis B virus (HBV) infection, your HBV may get worse (flare-up) if you stop taking TRIZIVIR. A “flare-up” is when your HBV infection suddenly returns in a worse way than before. Worsening liver disease is serious and may lead to death.
    • Do not run out of TRIZIVIR. Refill your prescription or talk to your healthcare provider before your TRIZIVIR is all gone. • Do not stop TRIZIVIR without first talking to your healthcare provider.
    • If you stop taking TRIZIVIR, 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 TRIZIVIR 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 TRIZIVIR and interferon with or without ribavirin, tell your healthcare provider if you have any new symptoms.


TRIZIVIR is a prescription HIV-1 (Human Immunodeficiency Virus type 1) medicine used alone or with other antiretroviral medicines to treat HIV-1 infection. HIV-1 is the virus that causes Acquired Immune Deficiency Syndrome (AIDS). TRIZIVIR contains 3 prescription medicines, abacavir (ZIAGEN®), lamivudine (EPIVIR®) and zidovudine (RETROVIR®).

TRIZIVIR should not be used in children weighing less than 88 pounds (40 kg).

When used alone or with other antiretroviral medicines to treat HIV-1 infection, TRIZIVIR may help:

  • reduce the amount of HIV-1 in your blood. This is called “viral load”.
  • increase the number of CD4+ (T) cells in your blood, that help fight off other infections.

Reducing the amount of HIV-1 and increasing the CD4+ (T) cells in your blood may help improve your immune system. This may reduce your risk of death or getting infections that can happen when your immune system is weak (opportunistic infections).

TRIZIVIR does not cure HIV-1 infection or AIDS. You must keep taking HIV-1 medicines to control HIV-1 infection and decrease HIV-related illnesses.

Avoid doing things that can spread HIV-1 infection to others.

  • Do not share or re-use needles or other injection equipment.
  • Do not share personal items that can have blood or body fluids on them, like toothbrushes and razor blades.
  • Do not have any kind of sex without protection. Always practice safer sex by using a latex or polyurethane condom to lower the chance of sexual contact with any body fluids such as semen, vaginal secretions, or blood.

Ask your healthcare provider if you have any questions about how to prevent passing HIV to other people.

Who should not take TRIZIVIR?

Do not take TRIZIVIR if you:

  • have a certain type of gene variation called the HLA-B*5701 allele. Your healthcare provider will test you for this before prescribing treatment with TRIZIVIR.
