Warning

In some patients, the abacavir in this product has caused a serious (sometimes fatal) allergic reaction. Your doctor should order a blood test to measure your risk before you start this medication or take it again. If the blood test shows you are at greater risk, you should not take this medication and your doctor should discuss other treatment choices with you. Symptoms of an allergic reaction may include any of the following: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing, fever, extreme tiredness, nausea, vomiting, diarrhea, stomach pain, muscle aches, sore throat, mouth sores, or cough. Get medical help right away if you experience any of these symptoms. If you have stopped taking abacavir because of an allergic reaction, you must never take any form of abacavir again, or death could result. Tell all of your doctors and pharmacists if you have stopped taking abacavir due to an allergic reaction. Also, properly throw away any unused medications containing abacavir. Read the warning card provided with this medication for more details.

The zidovudine in this product can decrease bone marrow function, which may lead to low numbers of red and white blood cells. A low number of red blood cells can lead to anemia. A low number of white blood cells can decrease your body's ability to fight serious, life-threatening infections. These serious side effects occur more often in people with advanced HIV disease (AIDS). Get medical help right away if you develop any signs of anemia (such as unusual tiredness, fast breathing, pale skin, fast heartbeat) or signs of infection (such as sore throat that doesn't go away, fever, chills, cough). Your doctor will check your blood cell counts while you are taking this medication to decrease the risk of these side effects.

Zidovudine may also cause muscle problems. Get medical help right away if you develop signs of muscle problems (such as wasting or decrease in muscle size, weight loss, muscle weakness/pain/tenderness).

Rarely, abacavir/lamivudine/zidovudine has caused severe (sometimes fatal) liver problems and a certain metabolic problem (lactic acidosis). Get medical help right away if you develop any of the following symptoms: nausea, vomiting, stomach/abdominal pain, unusual tiredness, dark urine, yellowing eyes/skin, deep/rapid breathing, or drowsiness. These serious side effects may occur more often in women and obese patients.

If you have hepatitis B infection and HIV, you may have a serious worsening of hepatitis symptoms if you stop taking lamivudine. Talk with your doctor before stopping this medication. Your doctor will monitor liver tests for several months after you stop lamivudine. Get medical help right away if you develop symptoms of worsening liver problems.
