Specific Precautions and Warnings for Ziagen

Some warnings and precautions to be aware of prior to taking Ziagen include the following:
 
  • Ziagen often causes allergic reactions. These reactions can be extremely dangerous. You should stop taking Ziagen and contact your healthcare provider immediately if you develop symptoms from two or more of the following groups of symptoms:

 

    • Group 1 -- Fever
    • Group 2 -- Rash
    • Group 3 -- Nausea, vomiting, diarrhea, or abdominal pain (stomach pain)
    • Group 4 -- Extreme fatigue, a general ill feeling (malaise), or achiness
    • Group 5 -- Shortness of breath, coughing, or a sore throat
If you have ever had an allergic reaction to abacavir, you should never take Ziagen (or any other medication containing abacavir) again. Recent research has discovered that people with a certain gene (known as the HLA-B*5701 allele) are at a high risk for an allergic reaction to Ziagen. It is now recommended that everyone be tested for this gene before starting the medication. If you have the gene, you should not take Ziagen. If you do not have the gene, an allergic reaction is still possible (but is much less likely).
  • Rarely, Ziagen can cause lactic acidosis or hepatic steatosis. These conditions are caused by damage to the liver and can be very dangerous. You are at a higher risk for these conditions if you have liver disease.

 

 

  • Ziagen can cause bone marrow depression, which means that the medication can decrease the bone marrow's ability to produce blood cells. This can lead to a variety of problems, such as anemia, frequent infections, or bleeding. Your healthcare provider should check your blood counts frequently while you are taking Ziagen.
     
  • Ziagen can change the distribution of fat on your body. The medication may cause you to gain fat in areas that are not typical for you, such as in the abdomen or at the back of the neck (a "buffalo hump"), and it may cause you to lose weight in other areas.
     
  • Ziagen is not a cure for HIV or AIDS. If you have HIV or AIDS, you should always use safer sex practices, regardless of whether you are taking medications.
     
  • As with all HIV medications, it is important that you take Ziagen exactly as prescribed. Missing doses may increase the chance of the virus becoming resistant to HIV medications.

 

  • When you first start taking this medication and your immune system begins to recover, a group of problems known as immune reconstitution syndrome may occur. Your immune system may start aggressively reacting to any infections you may have and may cause extreme inflammation. There have even been cases of autoimmune disorders (such as Graves' disease, polymyositis, and Guillain-Barré syndrome) possibly caused by this problem. 

 

  • Ziagen can interact with a number of different medications (see Ziagen Drug Interactions for more information).
     
  • Ziagen is considered a pregnancy Category C medication. This means that it may not be safe for use during pregnancy, although the full risks are not known (see Ziagen and Pregnancy).
     
  • It is not known if Ziagen passes through breast milk. Therefore, if you are breastfeeding or plan to start breastfeeding, discuss this with your healthcare provider prior to taking the drug (see Ziagen and Breastfeeding). It is important to understand that the HIV virus can be transmitted through breast milk and that breastfeeding is usually not recommended in women with HIV or AIDS.
