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


Group 2


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 abacavircontaining medicine (EPZICOM, TRIUMEQ, or ZIAGEN) again.

If you have an allergic reaction, dispose of any unused TRIZIVIR. Ask your pharmacist how to properly dispose of medicines.
If you take TRIZIVIR or any other abacavir‑containing medicine again after you have had an allergic reaction, within hours you may get lifethreatening 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, 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-1 (HIV-1) infection or Acquired Immune Deficiency Syndrome (AIDS). Your healthcare provider should check your blood cell counts regularly during treatment with TRIZIVIR.
Muscle pain or weakness can happen during treatment with TRIZIVIR. Zidovudine, one of the medicines in TRIZIVIR, can cause muscle pain or weakness when used for a long time.
Too much lactic acid in your blood (lactic acidosis). Lactic acidosis is a serious medical emergency that can lead to 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
Severe liver problems. In some cases, severe 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 or very overweight (obese).

Worsening of hepatitis B virus (HBV) infection. If you have HBV infection and take TRIZIVIR, 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.
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 function and monitor your HBV infection. It may be necessary to give you a medicine to treat HBV. Tell your healthcare provider about any new or unusual symptoms you may have after you stop taking TRIZIVIR.
Resistant HBV. If you have HIV-1 and HBV, the HBV can change (mutate) during your treatment with TRIZIVIR and become harder to treat (resistant).
Use with interferon and ribavirinbased 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 HIV-1 medicines and are also being treated for hepatitis C with interferon alfa with or without ribavirin. If you are taking TRIZIVIR and interferon alfa with or without ribavirin, tell your healthcare provider if you have any new symptoms.
