6.Contents of the pack and additional information

Ziagen is used in the treatment of infection caused by the HIV (human immunodeficiency virus).

Ziagen contains abacavir as its active ingredient. Abacavir belongs to a group of antiretroviral medications calledinhibitors of reverse transcriptase analogs of nucleosides(NRTIs).

Ziagen does not completely cure HIV infection; it reduces the amount of virus in the body and keeps it at a low level. It also increases the number of CD4 cells in the blood. CD4 cellsare a type of white blood cell that plays an important role in helping your body fight infection.

Not everyone responds to Ziagen treatment in the same way. Your doctor will monitor the effectiveness of your treatment.

Do not take Ziagen

• if you areallergic(hypersensitive)to abacavir (or to any other medicine that contains abacavir — such asTriumeq,TrizivirorKivexa) or to any of the other components ofthis medicine(listed in section 6).

If you have interrupted treatment with Ziagen

If for any reason, you have stopped taking Ziagen — especially because you think it has side effects or due to another illness:

If your doctor advises you to resume treatment with Ziagen, you can ask him to take the first doses in a place where you have easy access to medical assistance if necessary.

During treatment for HIV, there may be an increase in weight and levels of glucose and lipids in the blood. This may be partly related to recovery of health and lifestyle, and in the case of lipids in the blood, sometimes to the HIV medications themselves. Your doctor will monitor these changes.

Like all medications, this medication can produce side effects, although not everyone will experience them.

When you are being treated for HIV, it can be difficult to distinguish whether a symptom is a side effect of Ziagen or of other medications you are taking, or is due to an effect of the disease caused by HIV.Therefore, it is very important that you inform your doctor about any change in your health.
