    Before taking Ziagen

    You should not use Ziagen if:

  • you have moderate or severe liver disease;
  • you have a gene variation called HLA-B*5701 allele (your doctor will test you for this); or
  • you have had an allergic reaction to any medicine that contains Ziagen (such as Ziagen, Epzicom, Triumeq, or Trizivir).
  • Many combination HIV medicines have Ziagen as an ingredient. Ziagen should not be taken together with any other medicine that contains this medicine.

    You may develop lactic acidosis, a dangerous build-up of lactic acid in your blood. This may be more likely if you have other medical conditions, if you've taken HIV medication for a long time, or if you are a woman. Ask your doctor about your risk.

    Tell your doctor if you have ever had:

  • heart disease, high blood pressure;
  • a risk factor for heart disease such as smoking, diabetes, or high cholesterol;
  • liver disease; or
  • if you have used any other HIV medication in the past.
  • Tell your doctor if you are pregnant, and use your medications properly to control your infection. HIV can be passed to your baby if the virus is not controlled during pregnancy. Your name may be listed on a registry to track any effects of antiviral medicine on the baby.

    Women with HIV or AIDS should not breastfeed a baby. Even if your baby is born without HIV, the virus may be passed to the baby in your breast milk.
