Precautions

Drug information provided by: IBM Micromedex

It is very important that your doctor check the progress of you or your child at regular visits to make sure that this medicine is working properly. Blood tests may be needed to check for unwanted effects.

Do not take any other medicine containing emtricitabine, lamivudine, or zidovudine (eg, Atripla®, Complera®, Emtriva®, Epivir®, Epzicom®, Retrovir®, Trizivir®, or Truvada®).

Do not take any other medicines without checking with your doctor first. To do so may increase the chance of side effects from lamivudine and zidovudine combination.

If you or your child have both HIV and hepatitis B virus (HBV) infections, liver disease can become worse when lamivudine and zidovudine treatment is stopped. Discuss any changes in your treatment and medicines with your doctor.

Zidovudine may cause some serious side effects, including blood or bone marrow problems. Symptoms of a blood or bone marrow problem include fever, chills, sore throat, pale skin, or unusual tiredness or weakness. These problems may require blood transfusion or temporarily stopping treatment with lamivudine and zidovudine combination. Check with your doctor if any new health problems or symptoms occur while you or your child are taking lamivudine and zidovudine combination.

Two rare but serious reactions to this medicine are lactic acidosis (too much acid in the blood) and liver toxicity. These are more common if you are female, very overweight (obese), or have been taking anti-HIV medicines for a long time. Call your doctor right away if you or your child have more than one of these symptoms: abdominal discomfort or cramping, dark urine, decreased appetite, diarrhea, general feeling of discomfort, light-colored stools, muscle cramping or pain, nausea, unusual tiredness or weakness, trouble breathing, vomiting, or yellow eyes or skin.

Tell your doctor if you or your child have severe muscle pain, tenderness, or weakness, especially if you take this medicine for a long time.

When you or your child start taking HIV medicines, your immune system may get stronger. If you have infections that are hidden in your body (eg, pneumonia or tuberculosis), you may notice new symptoms when your body tries to fight them. If this occurs, tell your doctor right away.

This medicine may cause a decrease or loss of body fat, especially in your face, arms, legs, or buttocks, when it is used for a long time. Talk to your doctor if you have concerns.

This medicine does not decrease the risk of transmitting the HIV infection to others through sexual contact or by contaminated blood. Make sure you understand and practice safe sex, even if your partner also has HIV. Avoid sharing needles with anyone.
