(abacavir sulfate, lamivudine, and zidovudine) Tablets
Read this Medication Guide before you start taking TRIZIVIR and each time you get a refill. There may be new information. This information does not take the place of talking to your healthcare provider about your medical condition or your treatment. Be sure to carry your TRIZIVIR Warning Card with you at all times.
What is the most important information I should know about TRIZIVIR?
1. Serious allergic reaction (hypersensitivity reaction). TRIZIVIR contains abacavir (also contained in ZIAGEN® and EPZICOM®). Patients taking TRIZIVIR may have a serious allergic reaction (hypersensitivity reaction) that can cause death. 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 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 sulfate, lamivudine, and zidovudine) or any other abacavir-containing medicine (ZIAGEN and EPZICOM) 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.
2. Blood problems. 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 patients with advanced human immunodeficiency virus (HIV) disease or AIDS. Your doctor should be checking your blood cell counts regularly while you are taking TRIZIVIR. This is especially important if you have advanced HIV or AIDS. This is to make sure that any blood cell problems are found quickly.
3. Lactic Acidosis (buildup of acid in the blood). Some human immunodeficiency virus (HIV) medicines, including TRIZIVIR, can cause a rare but serious condition called lactic acidosis. Lactic acidosis is a serious medical emergency that can cause death and must be treated in the hospital.
Call your healthcare provider right away if you get any of the following signs or symptoms of lactic acidosis:
- you feel very weak or tired
- you have unusual (not normal) muscle pain
- you have trouble breathing
- you have stomach pain with nausea and vomiting
- you feel cold, especially in your arms and legs
- you feel dizzy or light-headed
- you have a fast or irregular heartbeat
4. Serious liver problems. Some people who have taken medicines like TRIZIVIR have developed serious liver problems called hepatotoxicity, with liver enlargement (hepatomegaly) and fat in the liver (steatosis). Hepatomegaly with steatosis is a serious medical emergency that can cause death.
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)
- your urine turns dark
- your bowel movements (stools) turn light in color
- you don't feel like eating food for several days or longer
- you feel sick to your stomach (nausea)
- you have lower stomach area (abdominal) pain
You may be more likely to get lactic acidosis or serious liver problems if you are female, very overweight, or have been taking nucleoside analogue medicines for a long time.
5. Use with interferon and ribavirin-based regimens. Worsening of liver disease (sometimes resulting in death) has occurred in patients infected with both HIV and hepatitis C virus who are taking anti-HIV medicines and are also being treated for hepatitis C with interferon with or without ribavirin. If you are taking TRIZIVIR as well as interferon with or without ribavirin and you experience side effects, be sure to tell your healthcare provider.
6. If you have HIV and hepatitis B virus infection, your hepatitis B virus infection may get worse if you stop taking TRIZIVIR.
- Take TRIZIVIR exactly as prescribed.
- Do not run out of TRIZIVIR.
- Do not stop TRIZIVIR without talking to your healthcare provider.
Your healthcare provider should monitor your health and do regular blood tests to check your liver if you stop taking TRIZIVIR.
7. Muscle weakness (myopathy). RETROVIR, one of the medicines in TRIZIVIR, can cause muscle weakness. This can be a serious problem.
What is TRIZIVIR?
TRIZIVIR is a prescription medicine used to treat HIV infection. TRIZIVIR contains 3 medicines: abacavir (ZIAGEN), lamivudine or 3TC (EPIVIR®), and zidovudine, AZT, or ZDV (RETROVIR). All 3 of these medicines are called nucleoside analogue reverse transcriptase inhibitors (NRTIs). When used together, they help lower the amount of HIV in your blood.
- TRIZIVIR does not cure HIV infection or AIDS.
- It is not known if TRIZIVIR will help you live longer or have fewer of the medical problems that people get with HIV or AIDS.
- It is very important that you see your healthcare provider regularly while you are taking TRIZIVIR.
Who should not take TRIZIVIR?
Do not take TRIZIVIR if you:
- are allergic to abacavir or any of the ingredients in TRIZIVIR. See the end of this Medication Guide for a complete list of ingredients in TRIZIVIR.
- have certain liver problems.
- are an adolescent who weighs less than 90 pounds.
What should I tell my healthcare provider before taking TRIZIVIR?
Before you take TRIZIVIR, tell your healthcare provider if you:
- have been tested and know whether or not you have a particular gene variation called HLA-B*5701.
- have hepatitis B virus infection or have other liver problems.
- have kidney problems.
- have low blood cell counts (bone marrow problem). Ask your doctor if you are not sure.
- have heart problems, smoke, or have diseases that increase your risk of heart disease such as high blood pressure, high cholesterol, or diabetes.
- are pregnant or plan to become pregnant. It is not known if TRIZIVIR
will harm your unborn baby. Talk to your healthcare provider if you are pregnant
or plan to become pregnant.
Pregnancy Registry. If you take TRIZIVIR while you are pregnant, talk to your healthcare provider about how you can take part in the Pregnancy Registry for TRIZIVIR. The purpose of the pregnancy registry is to collect information about the health of you and your baby.
- are breastfeeding or plan to breastfeed. Do not breastfeed. Lamivudine and zidovudine are excreted in human breast milk. We do not know if abacavir can be passed to your baby in your breast milk and whether it could harm your baby. Also, mothers with HIV-1 should not breastfeed because HIV-1 can be passed to the baby in the breast milk.
Tell your healthcare provider about all the medicines you take, including prescription and nonprescription medicines, vitamins, and herbal supplements.
Especially tell your healthcare provider if you take:
- medicines used to treat hepatitis viruses such as interferon or ribavirin
- BACTRIM®, SEPTRA® (trimethoprim [TMP/sulfamethoxazole SMX])
- CYTOVENE®, DHPG (ganciclovir)
- ADRIAMYCIN® (doxorubicin)
- COPEGUS®, REBETOL®, VIRAZOLE® (ribavirin)
- any bone marrow suppressive medicines or cytotoxic medicines. Ask your doctor if you are not sure.
- ATRIPLA® (efavirenz/emtricitabine/tenofovir disoproxil fumarate)
- COMBIVIR® (lamivudine and zidovudine)
- COMPLERA™ (emtricitabine/rilpivirine/tenofovir disoproxil fumarate)
- EMTRIVA® (emtricitabine)
- EPIVIR or EPIVIR-HBV® (lamivudine)

- RETROVIR (zidovudine)
- TRUVADA® (emtricitabine/tenofovir disoproxil fumarate)
- ZERIT® (stavudine)
