What is Combivir and what it is used
Combivir is used for the treatment of infection by human immunodeficiency virus (HIV) in adults and children.
Combivir contains two active substances which are used for the treatment of HIV infection: Zidovudine and Lamivudine. Both belong to the class of antiretroviral drugs called nucleoside analogue reverse transcriptase inhibitors (NRTIs).
Combivir does not cure HIV infection: it reduces the amount of virus in your body and keeps it at a low level. It also increases the number of CD4 cells in the blood. CD4 cells are a type of white blood cells that play an important role in keeping the immune system in order to be able to fight infections.
Not everyone responds to treatment with Combivir in the same manner. Your doctor will monitor the effectiveness of treatment.

2. What you should know before taking Combivir
Do not take Combivir:
if you are allergic to lamivudine or zidovudine or any of the other ingredients of this medicine (listed in Section 6);
